It has to be C- addition and subtraction signs.
Answer:
B : -2
Step-by-step explanation:
The value is 333
<h3>How to determine the function</h3>
From the information given, we have:
- x = - 8
- 1/3*h(x) = x^2-5x+7
Now, let's substitute the value of 'x' in the function:
1/3*h(x) = x^2-5x+7
1/ 3 × h(-8) = ( - 8)² - 5 ( -8) + 7
Make 'h ( -8)' the subject of formula
h ( -8) =
h ( -8) =
Take the sum of the numerator
h ( -8) =
Take the inverse of the denominator and multiply
h ( -8) = 111 × 3/ 1
h ( -8) = 333
We can see that through the substitute of the value of x as - 8, we get 333
Thus, the value is 333

20
This is because
2x+(6x+20)=180
8x+20=180
8x=160
8x/8=160/8
X=20
B) 11 over 8 Hope that is helpful
