Answer:

Yes, it is a function

Step-by-step explanation:

Every possible input x value is paired with a unique output y value.

Another approach is to graph the function then conduct the VLT (vertical line test) at which point you will realize that any vertical line will intersect the graph at one point only meaning it is a function.

Hope this helps.

Answer:

Jerry will earn the same as Victoria in 9 years.

Step-by-step explanation:

Giving the following information:

Jerry:

Net income= 45,000 + 2,500x

Victoria:

Net income= 54,000 + 1,500x

x= number of years

Now, we need to equal both formulas and isolate x:

45,000 + 2,500x = 54,000 + 1,500x

1,000x = 9,000

x= 9

Jerry will earn the same as Victoria in 9 years.

Prove:

Jerry= 45,000 + 2,500*9= $67,500

Victoria= 54,000 + 1,500*9= $67,500

11-20 please! I’m so confuzzled!

iren [92.7K]

I can help with 17-20:)
Slope = m = y2 - y1/ x2 -x1
So, you have already found the y1 and y2 and x1 and x2.
So, plug the numbers into the equation:
3 - 1/(-5) - (-2)
4 - (-3)/(-1) - 1
(-5) - 5/2 - 4
2 - (-1)/(-1) - 1
Then solve.
(Btw, the formula looks like this:
$\frac{y2 - y1}{x2 - x1}$
Hope this helps!!!
