Answer: (-2, 1), (-4, -3)
Step-by-step explanation:
y = x² + 8x + 13
y = 2x+5
x² + 8x + 13 = 2x+5
x² + 6x + 13 = 5
x² + 6x + 8 = 0
x² + 2x + 4x + 8 = 0
(x+2)(x+4)=0
<u>x=-2 or x=-4</u>
y=2(-2)+5
y=-4+5
<u>y=1</u>
y=2(-4)+5
y=-8+5
<u>y=-3</u>
The answer to this question is 100
Answer:
yes
Step-by-step explanation:

-7 is correct because a negative plus a negative is always a negative
Answer:the independent variable is x, the number of hours of work.
The dependent variable is y, the total charge for x hours of work.
Step-by-step explanation:
A change in the value of the independent variable causes a corresponding change in the value of in dependent variable. Thus, the dependent variable is is output while the independent variable is the input
For each visit, he charges $25 plus $20 per hour of work. The linear expression that represents the total amount of money that Ethan earns per visit is y = 25 + 20x.
Since the total amount charged, y depends on the number of hours of work, x, it means that the dependent variable is y and the independent variable is x
