Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
f(x) = -1x - 4
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em> [Function f(x)]: f(-3) = -1(-3) - 4
- Multiply: f(-3) = 3 - 4
- Subtract: f(-3) = -1
4 + 2x = 7
2x = 7 - 4 = 3
x = 3/2 = 1.5 inches
C, 180 i would guess without a picture. do you have a photo of the figure?
