the answer to your question would be D
Answer:
[-5,39]
Step-by-step explanation:
The vertex is at (-6,-5)
The interval is from -10 to 5 (inclusive of both endpoints...
Absolute function is open up because 4 is positive
I will plug in both endpoints now:
f(-10)=4|-10+6|-5 f(5)=4|5+6|-5
f(-10)=4(4)-5 f(5)=4(11)-5
f(-10)=11 f(5)=39
So the highest reached by f(5) which is 39 so our range will go up to 39 (inclusive)
11 is not the lowest reached, -5 is because our vertex was included within the domain
So the range is [-5,39]

Answer:
(3, - 1)
Step-by-step explanation:
5x - 4y = -11
2x + 3y = -9
Multiply the top equation by 2 and the bottom equation by - 5 to cancel out the x's.
10x - 8y = - 22
- 10x - 15y = 45
Cancel out x's.
-8y = - 22
- 15y = 45
Add like terms.
- 23y = 23
Can't have a negative variable to flip them.
-23 = 23y
Divide.
y = - 1
Input y into one of the equations and solve for x.
2x + 3(-1) = -9
Simplify.
2x -3 = -9
Cancel out -3 by adding 3.
2x = -6
Divide.
x - -3
