Let f(x)=7x-13. Find f^-1(x).

Ok but allow my humble self to use instead of .

We have,

If you wanna know what the inverse is swap the values of x and y,

And now solve for y,

.

Hope this helps.

The inverse function is (x+13)/7

Step-by-step explanation:

y = 7x-13

Exchange x and y

x = 7y -13

Solve for y

Add 13 to each side

x+13 = 7y-13+13

x+13 = 7y

Divide each side by 7

(x+13)/7 = 7y/7

(x+13)/7 = y

The inverse function is (x+13)/7

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
