please help determine if these are functions and explain why or why not
Answer:The first is a function but the second isn’t.
Step-by-step explanation: The numbers in the first circle (domain) should only point to one number in the second circle (range). Meaning the domain should only have one arrow for it to be a function. Therefore the first problem is a function, but the second problem is not. For
example, in the first problem, the 0 is only pointing to one number, the 2. However, in the second problem the 6 is pointing to two different numbers, the 3 and the 5. -Let me know if this helps you or if you want me to explain it more. Hope this helps! :)
PLS HELPPPP equation of the line that is parallel to the line y − 3x = 4 and passes through the point (0, −3)
Answer:
y = 3x - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
y - 3x = 4 ( add 3x to both sides )
y = 3x + 4 ← in slope- intercept form
with slope m = 3
Parallel lines have equal slopes, thus
y = 3x + c
The line crosses the y- axis at (0, - 3 ) ⇒ c = - 3
y = 3x - 3 ← equation in slope- intercept form

Can anyone helps me with this question. Look at the numbers ; 2,8,7,6,8,3,8. Find the
Mean
Median
Mode
Range
Answer:
1. Mean:
6
2. Median:
7
3. mode:
8
range:
6
Explanation:
Mean:
To find the mean you must add all the digits and divide them by the number of numbers there.for eg: 1,4,6,5,4
The number of numbers there is 5 so I added these numbers and divide them by 5.
Median:
To find the median you must arrange all the numbers in order and find the middle number eg: 1,2,3,4,5
The middle number is 3 as u can see there
Mode:
In the mode, you find the number that appears the most.
for eg: 1,3,3,4,5
The number appearing here the most is the 3
Range:
you minus the highest number from the lowest number
eg: 1,2,3,4,5
5-1 is 4 so the answer for the range is 4
James knows that when he walks, he takes about 120
120
steps per minute and that each step is 2.75
2.75
feet long. Which calculation is most reasonable for James to use to find out his walking speed in miles per hour?
Answer:
speed of James is: 3.75 miles/hour.
Step-by-step explanation:
We need to find the speed of James in miles per hour(mi/hr)
we know that 1 mile=5280 feet
James takes 120 steps in 1 minute so he will cover 120×60 steps in 1 hour.
i.e. he takes 7200 steps in 1 hour.
also each step of James=2.75 feet
total distance covered by James in 1 hour=2.75×7200 feet=19800 feet
[tex]19800feet=\frac{19800}{5280} miles=3.65miles[/tex]
hence speed of James= (distance covered by james in 1 hour)/1 hour
speed of James=3.75 miles/hour.

In order to evaluate energy demand for heating services, the number of heating degree days are calculated. The number of heating degree days can be calculated by the formula H = 65 - T, where 65 is degrees Fahrenheit, and T is the average of the high and low temperatures for the day. If the high temperature for a day was 51°F and the low temperature for the same day was 45°F, what is the number of heating degree days? A. 14 B. 113 C. 17 D. 48
Answer:
The number of heating degree days is 17 (option c).
Step-by-step explanation:
You know that the formula H = 65 - T, where 65 is degrees Fahrenheit, and T is the average of the high and low temperatures for the day.
You know that the high temperature for a day was 51°F and the low temperature for the same day was 45°F.
The mean, also called the average or arithmetic mean, is a measure of central position. In general, the average is calculated by adding all the figures or values presented and dividing them by the total number of values. So, in this case, the average of the high and low temperatures for the day is:
[tex]\frac{51 F + 45 F}{2}= 48 F[/tex]
The number of heating degree days can be calculated by:
H= 65°F - 48°F
H= 17 °F
The number of heating degree days is 17 (option c).

y = 1/2x - 2 Dave said his table
is correct. Bonnie said her
table is correct. Who is
correct? Explain your answer.
ILL PUT YOU AS BRAINLIEST
Answer:
Both tables are correct.
Step-by-step explanation:
The equation given is y = [tex]\frac{1}{2}[/tex] x - 2. When you replace x with each value given from Dave's table, the y values will be those given.
-4 = [tex]\frac{1}{2}[/tex] (-4) - 2
-3 = [tex]\frac{1}{2}[/tex] (-2) - 2
-2 = [tex]\frac{1}{2}[/tex] (0) - 2
-1 = [tex]\frac{1}{2}[/tex] (2) - 2
When you use the values given in Bonnie's table, the equations are also all true.
0 = [tex]\frac{1}{2}[/tex] (4) - 2
2 = [tex]\frac{1}{2}[/tex] (8) - 2
4 = [tex]\frac{1}{2}[/tex] (12) - 2
6 = [tex]\frac{1}{2}[/tex] (16) - 2

write a quadratic function f whose only zero is 7
well, we know is a quadratic, namely of degree 2, so it has two solutions and namely two factors, and whose only zero is 7, well, we can do that by giving that only zero a multiplicity of 2, so we get two of the same zero.
[tex]\begin{cases} x=7\implies &x-7=0\\ x=7\implies &x-7=0 \end{cases}\qquad \implies \qquad \begin{array}{llll} \stackrel{\textit{multiplicity of 2}}{(x-7)(x-7)}=\stackrel{0}{y} \\\\\\ x^2-14x+49=y \end{array}[/tex]
The quadratic function would be x² + 14x + 49 f whose only zero is 7.
What is a quadratic equation?The quadratic equation is defined as a function containing the highest power of a variable is two.
The standard quadratic function is given by ax² + b x + c = 0.
We know that is a quadratic of degree 2, so it has two solutions and two components, and its only zero is 7,
⇒ x = 7 and x = 7
⇒ x - 7 and x - 7
Thus, we can accomplish that by multiplying that singular zero by two, so we obtain two of the same zero.
⇒ (x - 7)(x - 7)
⇒ (x - 7)²
⇒ x² + 7²+ 2 × 7 × x
⇒ x² + 49 + 14x
⇒ x² + 14x + 49
Therefore, the quadratic function would be x² + 14x + 49.

Jane paid $40 for an item after she received a 20% discount. Jane's friend says this means that the original price of the item was $48.
Answer: she is wrong
Answer: her friend was wrong
Step-by-step explanation:
Jane’s friend found that 20% of 40 is 8. Then she added $8 to the sale price: 40 + 8 = 48. Then she determined that the original amount was $48.
b. Is her friend correct? Why or why not?
Jane’s friend was incorrect. Because Jane saved 20%, she paid 80% of the original amount, so that means that 40 is 80% of the original amount.

Select the correct answer in each of the following
Answer:
A, A and A
Step-by-step explanation:
Given
y = ax² + bx + c ( a ≠ 0 )
• If a > 0 then vertex is minimum
• If a < 0 then vertex is maximum
The graph here is a maximum, thus a < 0 → A
--------------------------------------------------------------------
The value of c is the y- intercept of the graph ( when x = 0 )
Since the y- intercept is below the x- axis then c < 0 → A
--------------------------------------------------------------------
The solutions to the equation are where the graph crosses the x- axis ( y = 0 )
Since the graph crosses the x- axis to the left of the y- axis, then
both solutions are negative → A
An angle measures 66° more than the measure of its complementary angle what is the measure of each angle
Answer:
The measures of the two angles are 12° and 78°
Step-by-step explanation:
Let us explain what is the complementary angles
Two angles are complementary if the sum of their measures is 90°
Example:
If m∠x + m∠y = 90°, then
∠x and ∠y are complementary angles
Let us solve the question
Assume that the measure of one of the complementary angle is x°
∵ The measure of its complementary is 66° more than it
∴ The measure of its complementary = x + 66
∵ The sum of the measures of the complementary angles is 90°
∴ x + 66 + x = 90
→ Add the like terms in the left side
∴ 2x + 66 = 90
→ Subtract 66 from both sides
∴ 2x + 66 - 66 = 90 - 66
∴ 2x = 24
→ Divide both sides by 2
∴ [tex]\frac{2x}{2}=\frac{24}{2}[/tex]
∴ x = 12°
→ Substitute the value of x in the second angle to find x
∵ The measure of the other angle = 12 + 66
∴ The measure of the other angle = 78°
∴ The measures of the two angles are 12° and 78°
Answer:
12 and 78
Step-by-step explanation:
Let us explain what is the complementary angles
Two angles are complementary if the sum of their measures is 90°
Example:
If m∠x + m∠y = 90°, then
∠x and ∠y are complementary angles
Let us solve the question
Assume that the measure of one of the complementary angle is x°
∵ The measure of its complementary is 66° more than it
∴ The measure of its complementary = x + 66
∵ The sum of the measures of the complementary angles is 90°
∴ x + 66 + x = 90
→ Add the like terms in the left side
∴ 2x + 66 = 90
→ Subtract 66 from both sides
∴ 2x + 66 - 66 = 90 - 66
∴ 2x = 24
→ Divide both sides by 2
∴
∴ x = 12°
→ Substitute the value of x in the second angle to find x
∵ The measure of the other angle = 12 + 66
∴ The measure of the other angle = 78°
∴ The measures of the two angles are 12° and 78°
A skydiver was directly above a ferris wheel when he jumped out of the plane. His friend was watching at the landing field and looking up at the airplane at an angle of 50°. The friend’s eyes were 5.5 feet above the ground when looking up, and he was standing 1050 ft from the ferris wheel. How high was the skydiver when he jumped?
Using the slope concept, it is found that the skydiver has at a height of 1257 ft when he jumped.
What is a slope?The slope is given by the vertical change divided by the horizontal change, and it's also the tangent of the angle of depression.
In this problem:
The vertical change is of x - 5.5, in which x is the skydiver's height.The horizontal change is of 1050 ft.The angle is of 50º.Hence:
[tex]\tan{50^\circ} = \frac{x - 5.5}{1050}[/tex]
[tex]x - 5.5 = 1.19175359259 \times 1050[/tex]
[tex]x = 1257[/tex]

A pack of cinnamon scented pencils sell for $4.00 what is the sales tax rate if the total cost of the pencils is $4.32
Answer:
8%
Step-by-step explanation:
To get the answer we can use proportion. We know that 4$ its 100% and 4.32 its 100% + taxes.
4$ ---------- 100%
4.32 -------- x
cross multiply now
4x=4.32*100%
4x=432% /:4
x=108%
We know that 4.32 its 100% + taxes=108% so to get taxes we have to subtract 108-100.
108%-100%=8% - its the answer.
Answer:
8%
Step-by-step explanation:
$4 represents the sale price
4.32 - 4 =$ .32 represents the sale tax
Tax rate is the percentage $ .32 out of $4.
4 is 100%
.32 is x%
Cross multiply to find x, and divide by 4
x= (.32·100) / 4
x = 8
The tax rate is 8%.
