Answer:

(5, -1) and (10, 2)

Step-by-step explanation:

*For (5,y)

<em>When</em><em> </em><em>x</em><em> </em><em>is</em><em> </em><em>5</em><em>,</em><em> </em><em>y</em><em> </em><em>is</em><em> </em><em>?</em>

3x-5y=20

3×5-5y=20

15-5y=20

-5y=20-15

-5y=5

y= 5/-5

y= -1

<em>When</em><em> </em><em>x</em><em> </em><em>is</em><em> </em><em>5</em><em>,</em><em> </em><em>y</em><em> </em><em>is</em><em> </em><em>-1</em><em> </em>

<em>(</em><em>5</em><em>,</em><em>-1</em><em>)</em>

*For (x,2)

<em>When</em><em> </em><em>x</em><em> </em><em>is</em><em> </em><em>?</em><em>,</em><em> </em><em>y</em><em> </em><em>is</em><em> </em><em>2</em>

3x-5y=20

3x-5×2=20

3x-10=20

3x=20+10

3x=30

x=30/3

x=10

<em>When</em><em> </em><em>x</em><em> </em><em>is</em><em> </em><em>1</em><em>0</em><em>,</em><em> </em><em>y</em><em> </em><em>is</em><em> </em><em>2</em>

<em>(</em><em>1</em><em>0</em><em>,</em><em>2</em><em>)</em>

Given f(x) = the quantity of 5x plus 1, divided by 2, solve for f−1(8).
aliina [53]
Hey there!

Your equation will be f(x) = (5x + 1) / 2. Now, you'll need to find the inverse.

In the equation, replace f(x) with y, then switch x and y. Now, solve for y in the new equation. What equals y will be your inverse equation. 

f(x) = (5x + 1) / 2
x = (5y + 1) / 2
(x)*2 = (5y + 1 / 2)*2
2x = 5y + 1
–1           –1
(2x – 1) / 5 = (5y) / 5
(2x – 1) / 5 = y

Your inverse function is f–1(x) = (2x – 1) / 5. Now, just plug in 8 for x and solve for the answer. 

f–1(x) = (2x – 1) / 5
f–1(8) = (2(8) – 1) / 5
f–1(8) = (16 – 1) / 5
f–1(8) = 15 / 5
f–1(8) = 3

Your final answer will be 3. Hope this helped you out! :-)
