To find the inverse of a function switch the place of y (aka f(x) ) with x. Then solve for y.
Original equation:
y = 4x + 5
Switched:
x = 4y + 5
Solve for y by isolating it:
x - 5 = 4y + 5 - 5
x - 5 = 4y
(x - 5)/4 = 4y/4

<em>Answer:</em>
<em>x = 3</em>
<em>Step-by-step explanation:</em>
<em>5(x - 2) – x – 5 = -3</em>
<em>5x - 10 - x - 5 = - 3</em>
<em>5x - x = 10 + 5 - 3</em>
<em>4x = 12</em>
<em>x = 12 : 4</em>
<em>x = 3</em>
Answer:
The number of sunny days this year = 0.75x
where, x is the sunny days in last years.
Step-by-step explanation:
Given - This year there was 25% fewer sunny days than last year.
To find - What is the number of sunny days this year?
Proof -
Let us assume that,
The total number of sunny days last year = x
Given that,
This year there was 25% fewer sunny days than last year.
i.e this year total sunny days = 100 - 25 = 75 %
So,
we get
If there were x sunny days last year,
Then,
This year Total sunny days = 0.75x
