Answer:
The equation of the perpendicular line:
2x + 5y = ╼ 15
Answer:
Step-by-step explanation:
9+9y=18y
9y-9= y
9(y-1)=9y−9 simplifed
9(y+1)=9*1y
9y+1=10y
1+9y=10y
sorry if I got some wrong I tried my best.

Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = -x
f(-3) is x = -3
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(-3) = -(-3)
- Multiply: f(-3) = 3

It's still just easier to add first though.
