Step-by-step explanation:

So, we can find the points to graph by looking at the table. The left column is where we find our x-values and the right column is where we find the y-values. We get the points (1, 3), (3, 9), (5, 15), and (6, 18). I added a picture showing where to plot these and hope it helps!!

What is the slope of the graph of 4 x + 8 y = 11?

Karolina [17]

Answer:

B -1/2

Step-by-step explanation:

4x+8y = 11

We need to get the equation in the slope intercept form

y = mx+b where m is the slope and b is the y intercept

Subtract 4x from each side

4x-4x+8y = -4x+11

8y = -4x+11

Divide by 8

8y/8 = -4x/8 +11/8

y = -1/2x +11/8

The slope is -1/2 and the y intercept is 11/8

F(x)=2x+1/x-1 then f^-1(1)

olasank [31]

Answer:

f⁻¹(x) = (x + 1) / (x - 2)
f⁻¹(1 ) = - 2

Step-by-step explanation:

<u>Given function:</u>

f(x) = (2x + 1) / (x - 1)

<u>Find its inverse, substitute x with y and f(x) with x, solve for y:</u>

x = (2y + 1) / (y - 1)
x(y - 1) = 2y + 1
xy - x = 2y + 1
xy - 2y = x + 1
y(x - 2) = x + 1
y = (x + 1) / (x - 2)

<u>Substitute y with f⁻¹(x):</u>

f⁻¹(x) = (x + 1) / (x - 2)

<u>Find f⁻¹(1 ):</u>

f⁻¹(1 ) = ( 1 + 1) / (1 - 2) = 2 / - 1 = - 2
