40=80%
divide both sides by 4 and you have:
10=20%
There are 5 20s in 100 so you multiply both sides by 5 so it is:
50=100%

Hope this helps :)

Consider this function. f(x) = -3x +3 Which graph represents the inverse of function f?
lesya692 [45]

The inverse of the given function is y = 3-x/3. The graph is attached below.

<h3>Inverse of a function</h3>

Functions are written in terms of variables. Given the linear function

f(x) = -3x + 3

Find the inverse

y = -3x + 3

Replace the variables

x = -3y + 3

Make y the subject of formula

3y = -x + 3

y = 3-x/3

Plot the graph of the resulting function

Luda [366]

Answer:

The length of XY is 11.

Step-by-step explanation:

since the triangles are congruent to one another,

(4x-7)=(2x-3)

move the like terms to the other side

4x-2x=-3+7

2x=4

x=4

then subsitute x into the equation

2(4)+3

= 11
