Sketch a graph that has the following characteristics.

A. crosses the y-axis at (0,4)
B. increases in the interval -12 ≤x ≤-2
C. Constant in the interval -2 ≤ x ≤ 2
D. Decreases in the interval 2 ≤ x ≤12

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15

1/4 is the asnwer cuz 5/20 is the faction
