Evaluate f(x) = 5x – 8 when 8 when I = -3.0, and 4.​

f(3)=3

Step-by-step explanation:

Plugin 3 for x, and simplify

f(x) =5(x)−12

f(3) =5(3)−12

=15−12

f(3)=3

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
