It’s A!! hope that helped
Hello!
You put -1 in for x
F(-1) = (-1)^5 + (-1 + 3)^2
F(-1) = -1 + (2)^2
F(-1) = -1 + 4
F(-1) = 3
The answer is 3
Hope this helps!
Answer:
- h(x) = -2x^2 -x +3
- Reservoir A releases the same amount of water as Reservoir B over 1 week
Step-by-step explanation:
<u>Given</u>:
f(x) = x^2 -7x +5
g(x) = 3x^2 -6x +2
h(x) = f(x) -g(x)
<u>Find</u>:
h(x)
h(1)
<u>Solution</u>:
The expression for h(x) is found by evaluating its definition:
h(x) = (x^2 -7x +5) -(3x^2 -6x +2)
h(x) = x^2(1 -3) +x(-7 -(-6)) +(5 -2)
h(x) = -2x^2 -x +3
Then h(1) is found by substituting 1 for x:
h(1) = -2(1^2) -(1) +3 = -2 -1 +3
h(1) = 0 . . . . difference in release amounts after 1 week is 0
The true statements are ...
- h(x) = -2x^2 -x +3
- Reservoir A releases the same amount of water as Reservoir B over 1 week
Answer:
Step-by-step explanation:
n is a variable and multiplied by 6, so it is attached to 6. (6 is known as the coefficient.) Then it is divided by 4. (4 is known as the constant because there is no variable attached to it.)

Hi there!
The correct answers for the question are:
For 45 mph, the trip time is: 9.78
For 55 mph, the trip time is: 8.36
For 65 mph, the trip time is: 7.38
Step-by-step explanation:
The values given to you represent the variable "S" so therefore you just plug in the values into the equation and you get "t"
