Given the equation y= -3x+2.5, when y is 8.5, what value of x makes the equation true?
PLEASE EXPLAIN HOW YOU GOT YOUR ANSWER AS WELL !! ( im not very smart :c )
Answer:
x= -2
Step-by-step explanation:
First, write your equation with 8.5 substituted for y: 8.5= -3x +2.5
Next, subtract 2.5 from both sides to simplify the equation: 6= -3x
After that, divide both sides by -3 to get x by itself: -2 = x
So, when y=8.5, x=-2.
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

Calculate the slope of the line with points (3, 2) and (6, 4). Write your answer as a decimal rounded to 2 decimal places.
Answer:
0.67
Step-by-step explanation:
m is the slope
The formula is m=[tex]\frac{y_{2}-y_1}{x_2-x_1}[/tex]
m= [tex]\frac{4-2}{6-3}[/tex]
m= [tex]\frac{2}{3}[/tex]
2÷3=0.66666...≈0.67

Dave and Bonnie each made a
table of values for the equation
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

At a concert, tickets cost either $40 or $60. 700 tickets were sold at a cost of $33600. Find how many $40 tickets were sold.
Answer:
420
Step-by-step explanation:
Let x = number of $40 tickets.
Let y = number of $60 tickets.
x + y = 700
40x + 60y = 33600
-40x - 40y = -28000
20y = 5600
y = 280
x + y = 700
x + 280 = 700
x = 420
Answer: 420 $40 tickets were sold

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

Correct Question
A dentist is making identical dental care bags for patients using 56 tubes of toothpaste, 112 packets of floss, and 84 toothbrushes. What is the greatest number of identical dental care bags the dentist can make with the least amount of items leftover? Describe the contents of each bag.
Answer:
What is the greatest number of identical dental care bags the dentist can make with the least amount of items leftover?
28 identical dental care bags
Describe the contents of each bag.
2 tubes of toothpaste, 4 packets of floss and 3 toothbrushes.
Step-by-step explanation:
We solve for this using greatest common factor method
Step 1
Find the factors of 56, 84 and 112
The factors of 56 are: 1, 2, 4, 7, 8, 14, 28, 56
The factors of 84 are: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84
The factors of 112 are: 1, 2, 4, 7, 8, 14, 16, 28, 56, 112
The greatest common factor amongst them is = 28
Hence, the greatest number of identical dental care bags the dentist can make with the least amount of items leftover is 28 bags.
Describe the contents of each bag.
Each bag should contain 2 tubes of toothpaste, 4 packets of floss and 3 toothbrushes.
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.
0 20% 40% 60% 80% 100%
0 10 20 30 40 50
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.

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.

Lauren's net pay after deductions will be equal to $623.52
What will be the net pay of Lauren?The net pay of the Lauren will be calculated as
The gross pay is = $ 765
The Federal tax = $68
Social security tax on gross pay 6.2%= [tex]SST=765\times 0.062=47.43[/tex]
Medicare tax on gross pay 1.45%= [tex]765\times 0.0145=11.09[/tex]
State tax on federal tax holdings 22% =[tex]68\times 0.22=14.96[/tex]
Now the net pay will be
[tex]=765-68-47.43-11.09-14.96=623.52[/tex]
Thus Lauren's net pay after deductions will be equal to $623.52

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).
