What is f(-3) if f(x) = |2x - 1| - 5?

f(x)=|2x+1|+5

f(-3) = |2*-3 + 1|+5

       = |-6 + 1|+5

       = |-5|+5  = 5 + 5 = 10

f(-3) = 10

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
