Answer:

f^{-1}(x)=4x+20

Step-by-step explanation:

<u>Given</u>

<u />f(x)=\frac{x}{4}-5\\ \\y=\frac{x}{4}-5

<u>Swap x and y and solve for y</u>

<u />y=\frac{x}{4}-5\\ \\x=\frac{y}{4}-5\\ \\x+5=\frac{y}{4}\\ \\4(x+5)=y\\\\y=4x+20

<u>Final answer</u>

<u />f^{-1}(x)=4x+20

Keep in mind that we need to swap the variables because a function and its inverse are symmetrical about the line y=x. See the graph below.

1 5 (25−5a)=4−a solve for a
Vitek1552 [10]

Answer:

5.01 is your answer.

Step-by-step explanation:

What you do is you have to get a by itself.

<em>15 (25 - 5a) = 4 - a</em>

<em>375 - 75a = 4 -a</em>

<em>-74a + 375 = 4</em>

<em>-74a = -371</em>

<em>a = 5.01 rounded to the nearest hundreth</em>

5.01 is your answer.
