Answer:
77 inches
Step-by-step explanation:
W= width
L=Length
4+w=L
4+w+4+w+w+w
4w+8=36
4w+8-8=36-8
4w=28
4w/4=28/4
w=7
4+7=11
L=11
w=7
11 x 7=77
<u>Final answer</u>
77 inches
Answer:
To find an inverse, you need to replace f(x) with y. Then switch the x and y's in your equation and solve for y. This will find f^-1(x).
Step-by-step explanation:
19x+12y=17
step 1: move the thing that you're looking for to the left side and all the rest to the right side:
(19x +12y)-19x = 17 -19x
12y = 17 -19x
step 2: to find y, you need to get rid of 12. to do so you need to devide everything by that number:
(12y)/12 = 17/12 -19/12 x
y= 17/12 -19/12 x
step 3: simplify of possible. ( in this exercise it isnt)
step 4: rearange the equation if necessary
y= 17/12 + -19/12x
y= -19/12x + 17/12
