Answer:
What is this?
Step-by-step explanation:
If Melanie get's 4.10$, then Jacob get's 20.50$.
We can divide to get the unit rate:
20.50 ÷ 4.10 = 5
This means that if Jacob gets 5$, then Melanie will get 1$.
So in this case, Melanie get's 1$.
Answer:
x=2
y=7
Step-by-step explanation:
Since we know that the object is a rectangle, we know that the opposite sides are equal to each other. Thus:
9 = y+2
and
2y = 7x
Using algebra we can solve the first equation:
9 = y+2
9-2 = y
7 = y
Now we can use substitution:
2y = 7x
2(7)=7x
14=7x
x=2
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
