8. Suppose v varies directly as g, and v = 36 when g = 4. Find v when g = 11. v = 9. Suppose a varies directly as b, and a = 7 when b = 2. Find b when a = 21. b =

10. Suppose y varies directly as x, and y = 9 when x = 3/2. Find y when x = 1. y =

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

answer: i guess 5 units?

step-by-step explanation:

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
