Perimiter=sum of all sides

add 8 both sides
3x=27
divide both sides by 3
x=9 inches

x=9 in

HELP ASAP
Natalija [7]

Answer:

The equation of the function: y = mx + b

  • m = slope = (y₂ - y₁)/(x₂ - x₁) = [5 - (-3)]/(4 - 0) = (5 + 3)/4 = 8/4 = 2
  • b = y-intercept = -3

Therefore, the equation is <u>f(x) = 2x - 3</u>

When x = 0, f(x) = 2(0) - 3 = <u>-3</u>

When x increases by 1, f(x) increases by <u>2</u> (slope = the rate of change)
