Answer:
y = 6x + 104
Step-by-step explanation:
Given the equation in the form:
y = mx + b
m = slope ; b = intercept
Given the data:
5 days - $134 10 days - $164 15 days - $194 20 days - $224
To obtain the slope, Pick the points :
(5, 134) and (20, 224)
Slope = y2 - y1 / x2 - x1
Slope, m = (224 - 134) / (20 - 5) = 90 / 15 = 6
Plugging into the equation :
We have ;
y = 6x + b
Picking any point from the data and plugging in to solve for b:
(10, 164)
164 = 6(10) + b
164 = 60 + b
b = 164 - 60
b = 104
Equation finally becomes ;
y = 6x + 104
question “If y =5, what is the value of the following expression
7+2y²
Answer:
57
Step-by-step explanation:
Hey there!
To find the solution, plug in 5 for y. When you do this you get, 7+2(5)². Square the 5 to get 25. And then you att 7+2(25). 25 x 2 is 50. 50 +7 is 57.

Identify a set of parallel lines and a set of perpendicular lines in this image
Answer
It is the first answer.
Step-by-step explanation:
Parallel lines are lines that will never cross each other.
Perpendicular lines are lines that cross each other at 90 degree angles (represented by the box in the corner).
A set of parallel lines and a set of perpendicular lines in this image are; AB║CD, CD ⊥ EF and AB ⊥ EF
How are parallel straight lines related?Parallel lines have the same slope since the slope is like a measure of steepness and since parallel lines are of the same steepness, thus, are of the same slope.
Since Parallel lines are lines that will never cross each other.
We know that Perpendicular lines are lines that cross each other at 90 degree angles.
The parallel lines are AB and CD, the perpendicular are AB and EF because the first sets are side by side and the second sets cross each other at a certain point.
Therefore the set of parallel lines and a set of perpendicular lines in this image are; AB║CD, CD ⊥ EF and AB ⊥ EF

Hamburger Heaven is having a lunch special where customers buy one 3/4-pound cheeseburger and get one free. If they set aside 130 2/3 pounds of meat, how many 3/4-pound cheeseburgers can they make?
Answer:
174 cheeseburgers
Step-by-step explanation:
The computation of the number of 3 by 4 pound cheese burgers made is shown below:
3 by 4 would be written as 0.75 pound
And, 130 2 ÷ 3 = 130.66667 pounds
Now the number of 3 by 4 pound cheese burgers made is
= 130.66667 pounds ÷ 0.75 pound
= 174.22
= 174 cheeseburgers

To find:
The simplified form of the given expression.
Solution:
We have,
[tex]-3\sqrt{50a^2b^2}[/tex]
It can be written as
[tex]=-3\sqrt{2\times 25a^2b^2}[/tex]
[tex]=-3\sqrt{2\times 5^2a^2b^2}[/tex]
Using the properties of radical and logarithm, we get
[tex]=-3\sqrt{2\times (5ab)^2}[/tex] [tex][\because (mn)^x=m^xn^x][/tex]
[tex]=-3\sqrt{2}\times \sqrt{(5ab)^2}[/tex] [tex][\because \sqrt{mn}=\sqrt{m}\sqrt{n}][/tex]
[tex]=-3\sqrt{2}\times 5ab[/tex]
[tex]=-15\sqrt{2}ab[/tex]
Therefore the simplified form of the given expression is [tex]-15\sqrt{2}ab[/tex].

Andrew collects coins. He collected a total of 275 coins. If 84% of the coins he collected were foreign, how many other coins did he collect? Andrew collected coins that were not foreign
Answer:
44
Step-by-step explanation:
1. Find out how many coins were foreign
x. 84
------ = ---------
275. 100
2. Subtract 231 (Foreign coins) by 275 (Total coins)
3. The answer is 44
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
The number of foreign coins.
84% of 275 = 231
The number of foreign coins is 231.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Total number of coins = 275
Percentage of foreign coins = 84%
The number of foreign coins.
= 84% of 275
= 84/100 x 275
= 231
Thus,
The number of foreign coins is 231.

Step-by-step explanation:
90+2x+x=180
3x=90
x=30
Answer:
30
Step-by-step explanation:
First we can find the total angle that we are "adding" to. This total angle is 180 degrees. Now since there is a right angle, H,E,G, we can remove 90 from that total to get 90. Now for x. Since there is a total of 3 x's, we divide 90 by 3 to get 30.

which value of x makes the equation 1.25(4 x-10)=7.5 true?
A. 3.5
B. -1
C. -0.5
D. 4
Answer:
4
Step-by-step explanation:
1.25(4x-10)=7.5
First step is to divide the 1.25 on both sides
4x-10 = 6
next step is to get x by itself by adding 10 to both sides
4x = 16
continue getting x by itself by dividing both sides by 4
x = 4.
Write the equation of the line in slope intercept form that has a slope of -1/5 and contains (-5,-3)
Answer:
y = [tex]-\frac{1}{5}x[/tex] - 4
Step-by-step explanation:
As we know the point slope form of an equation is as follows -
y - y₁ = m ( x - x₁ )
As we have slope , m = [tex]-\frac{1}{5}[/tex]
And point (x₁ , y₁ ) = ( -5, -3)
⇒ y - ( -3) = [tex]-\frac{1}{5}[/tex] ( x - (-5) )
⇒ y + 3 = [tex]-\frac{1}{5}[/tex] ( x + 5 )
⇒ y + 3 = [tex]-\frac{1}{5}[/tex] x - 1
⇒ y = [tex]-\frac{1}{5}[/tex] x - 1 - 3
⇒ y = [tex]-\frac{1}{5}[/tex] x - 4
So, the equation becomes
y = [tex]-\frac{1}{5}x[/tex] - 4

What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
As, we know that The median (also called a midline or midsegment) is a line segment half-way between the two bases.
median = (a+ b ) / 2
So, 12.5 = (3x+1 + 15) / 2
12.5 = 3x + 16 / 2
25 = 3x + 16
3x = 9
x= 3
Hence, the value of x is 3.
