Answer:
- 8
Step-by-step explanation:
To evaluate f(8) substitute x = 8 into f(x)
f(8) = - 2(8) + 9 = - 16 + 9 = - 7
Similarly for g(- 1)
g(- 1) = (- 1)² - 2 = 1 - 2 = - 1
Then
f(8) + g(- 1) = - 7 + (- 1) = - 7 - 1 = - 8
Here you go, hope it helps!

Answer:
1. 1.28
2. 55
3. +
Step-by-step explanation:
1. 0.043 x 10 {3}
= 0.043 x (10 x 3)
= 0.043 x 30
= <u>1.28</u>
2. 5 + (9) (6) - 4
= 5 + 9 x 6 - 4
= 5 + 54 - 4
= 59 - 4
= <u>55</u>
