Answer:
x + 3 / 2 = y
Step-by-step explanation:
to change a function to its inverse we need to do three basic things
1. change f(x) to y
so for the example i gave which is f(x) = 2x - 3; this will now be
y = 2x - 3
2. we need to switch the position of the x's and y's, that means x becomes y and y becomes x
x = 2y - 3
3. finally we make y the subject of the formula
x + 3/ 2 = y, this new expression for y is the inverse of the function and can be written as
f^-1(x) = x + 3/2
A). Is correct you can thank me later ;)
If you subtract 4 from both sides your left with 15, then divide by 3 to find x. your left with x=5
Step-by-step answer:
1/8" long piece is not very much. However, mathematically,
we divide the total length by the length of each piece to get the number of pieces. So
4 2/5 / (1/8)
= (5*4+2)/5 * (8/1) [convert to fraction, and division to multiplication
= (22/5) * (8/1)
= 176/5
= 35 pieces with 1/5" left over.
