The function h(x) is given below. h(x) = {(3, -5), (5, -7), (6,-9), (10, -12), (12, -16)}
Which of the following gives h-'(x)?
O {(3,5), (5,7), (6, 9), (10, 12), (12, 16)}
O {(-5,3), (-7, 5), (-9, 6), (-12, 10), (-16, 12)}
{(3,-5), (5, -7), (6,-9), (10,-12), (12,-16)}
{(1, 3), (7,5), (9,6), (12, 10), (16, 12)}

32/80  

91/140

the last one 54 doesn't go into 45. 54/100 ?

step-by-step explanation:

they would have to work 32 hours.

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
