Answer:
Step-by-step explanation:
Answer:
30+(2x+7)+63=180(sum of angles of triangle )
30+2x+7+63=180
2x+100=180
2x=180-100
x=80/2
x=40

Step-by-step explanation:
<u>Step 1: Define</u>
g(x) = -x² + 10x - 3
g(9) is x = 9
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: g(9) = -(9)² + 10(9) - 3
- Exponents: g(9) = -(81) + 10(9) - 3
- Multiply: g(9) = -81 + 90 - 3
- Add: g(9) = 9 - 3
- Subtract: g(9) = 6
Answer:
x=5
Step-by-step explanation:
We want the x value when the output is 3
This occurs at -7 and at 5
We want the x value other than -7 so x=5
