3/4 of the circle is shaded because there is 4 parts and only 3 are shaded in
Answer:
Firstly
f(x)=3x-2=y then
Interchanging x and y we get
x=3y-2
x+2=3y
y=(x+2)/3
f-1(x)=(x+2)/3
f-1(13)=(13+2)/3
f-1(13)=5
Answer:
x = 40
Step-by-step explanation:
.80x + 30 = 1.20x + 14
<u>-.80x = -.80x </u>
30 = .4x + 14
<u> -14 = -14</u>
16 = .4x
16/.4 = .4/.4x
40 = x
Its eliminating. You will need to make the conditions on each side just as much alike as possible in the two equations for simple thought method
