Of Mr. Hallman puts 3 filters on, what percentage of sunlight will pass through to the lens? How much would pass through 5 filters

f(x) = y

f(-3) = -5

step-by-step explanation:

the answer is b.

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
