Answer:
Minimum value of f(x) = -1.
Step-by-step explanation:
We convert it to vertex form:
x^2 - 6x + 8
= (x - 3)^2 - 9 + 8
= (x - 3)^2 - 1
The minimum value occurs when (x - 3)^2 = 0 because a square has a minimum value of zero ( it cannot be negative for real values of x).
So the function has a minimum value of -1.
I would think it would be b for task 3
$128
We have the rate “$176 for 11 hours of work”
Find the unit rate of dollars per hour by:
Divide 176 ÷ 11 = 16
UNIT RATE: $16 per hour
Now find how much dollars for 8 hours by:
Multiply 16 • 8 = 128
FINAL ANSWER:Mary would earn $128 for 8 hours of work

Answer:
x = 3
Step-by-step explanation:
First you want to divide both sides by 5 to get 2x-4 = 2.
Afterwards, you add 4 to both sides of the equation. 2x = 6
Divide both sides by 2. x = 3
