Answer:
y = 4/3x -4
Step-by-step explanation:
4x -3y =12
move the variable to the right
-3y = 12 -4x
Change the signs
3y= -12 +4x
Divide both sides
y = -4 + 4/3x
Answer: y = 4/3x -4
Hope that helps!
The inverse of the given function is expressed as y = ±√x + 38
<h3>Inverse of an equation</h3>
Given the equation below expressed as:
y = x² - 36
Replace y with x
x = y² - 38
Add 38 to both sides of the equation
x + 38 = y² - 38 + 38
y² = x + 38
Take the square root of both sides
√y² = ±√x + 38
y = ±√x + 38
Hence the inverse of the given function is expressed as y = ±√x + 38

Answer:
x = 50
Step-by-step explanation:
-3(52)=-3(x)+-3(2)
Divide both sides by -3
52 = x + 2
x = 50
Answer:
64 textbooks
Step-by-step explanation:
the first two teachers had 21 students each that's 21+21=42
the other teacher had 22 students so apparently all the textbooks handed to the students are,21+21+22=64
\/(5x) = x\/5
[\/(5x]² = [x\/5]²
5x = 5x²
5x²-5x = 0
5x(x-1) = 0
5x = 0 --> x = 0
x-1 = 0 --> x = 1
