h
(x) =
x + 2
eplace f(x) with y
swtich x and y
solve for y
replace y with f⁻¹(x)
f(x)=4x+8
y=4x+8
x=4y+8
x-8=4y
1/4x-2=y
y=1/4x-2
f⁻¹(x)=1/4x-2
none of the above
we are given
Since, we have to solve for r
so, firstly we will isolate r terms
so, we will move 12 on right side
we can add both sides by 12
now, we can divide both sides by 5
now, we can take sqrt both sides
and we get
so,
{±4}..........Answer
The elevator at the local mall has a weight limit of 1,800 pounds is
9w ≤ 1800.
Inequalities are mathematical formulas in which neither side is equal. Unlike equations, we compare two values in inequality. In between, the equal sign is substituted by a less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
The elevator at the local mall has a weight limit of 1,800 pounds.
Not more than 9 people allowed in the Elevator.
let the weight of one person be w.
Then, the inequality is
9w ≤ 1800
