Look at this function: x y −12 −8 −8 −6 −4 −4 0 −2 Mina said that the function is linear. Jenna said that the function is nonlinear. Which of the following explains who is correct?
Mina, because for every 2-unit increase in x, there is an increase in y by 4
Mina, because for every 4-unit increase in x, there is an increase in y by 2
Jenna, because the point (0, −2) does not lie on the straight line that contains the other points
Jenna, because the point (−12, −8) does not lie on the straight line that contains the other points
C. Because (0,-2) has a y that is 4 greater but the x is 4 greater and everything else is x+4 y+2
The graph is nonlinear, the correct option is, "Jenna, because the point (0, −2) does not lie on the straight line that contains the other points".
What is linear and nonlinear function?A linear function gives a graph that is a straight line. On the contrary, a nonlinear function gives a graph that is not a line.
Given are coordinates, (x, y) = (−12, −8), (−8, −6), (−4, −4) and (0, −2)
The graph of these coordinates is not linear, because (0,-2) has a y that is 4 greater and the x is also 4 greater and other points are (x+4, y+2)
Hence, the correct option is "Jenna, because the point (0, −2) does not lie on the straight line that contains the other points".

Jason and Adam are using a kit to build their own electronics board for a computer project. They use a scale drawing included in the instructions to help build the board. Jason will use the scale factor to find the board's actual length and width, then multiply those dimensions to find the board's area. Adam says he knows another way. Answer the questions to show how Adam could find the area of the scale drawing, and then use this strategy to find the area of the electronics board. 1. What is the area of the board shown on the scale drawing? Explain how you found the area. Write your answer in the space below. 2. How can Adam use the scale factor to find the area of the actual electronics board? Remember, he uses a different method than Jason. Write your answer in the space below. 3. What is the area of the actual electronics board? Write your answer in the space below.
Answer:
1. Area is 1800 cm. I found this out by multiplying 36 and 50 together.
2. He can figure out that the scale factor 5:1 means that 1 cm in the drawing is 0.2 cm in reality, so he would take 36 and 50 and multiply them both by 0.2 cm then add them to get 17.2, which is the actual area of the rectangle.
3. Actual area is 17.2

a collection of coins consist of nickels, dimes, and quarters. there are 3 fewer quarters than nickels and six more dimes than quarters. how many of each kind of coin is in the collection if the total value of the collection is $4.35?
Using a system of equations, there are 9, 12 and 15 quarters, nickels and dimes respectively.
Creating a system of equations thus :
n + d + q = 36 - - - (1)n = q + 3 - - - (2).d = q + 6 - - - (3)Substitute for n and q
(q+3) + (q+6) + q = 36
3q + 9 = 36
3q = 36 - 9
q = 27 ÷ 3
q = 9 quarters
n = 9 + 3 = 12 nickels
d = 9 + 6 = 15 dimes
Hence, there are 9, 12 and 15 quarters, nickels and dimes respectively.
