Answer:
C. 5/7
Step-by-step explanation:
You mean -2x+5y=20 if it was that's how you do it
so if you're finding the x intercept the y will turn to 0 why because you're only looking for x their's no need for y
so it will be -2x+0=20
-2x=20 if it's multiplication then you change it to division
-2x/-2=20/-2
x=-10
Answer:

Step-by-step explanation:
We are given the function:

Let's find the inverse of g.
Call y=g(x):

We need to solve for x. Multiply both sides by x-2 to eliminate denominators:

Operate:

Collect the x's to the left side and the rest to the right side of the equation:

Factor the left side and operate on the right side:

Solve for x:

Interchange variables:

Call y as the inverse function:

Answer:
Step-by-step explanation:
As per definition of the function, every x- value (input) has exactly one corresponding y-value (output)
<u>We can see on the table:</u>
- x = 3.45 and y= 1.72
- x = 3.45 and y = 3.36
Two same input values with different outputs.
So this not a function
