Answer:
y = √(4x - 8) - 3
Step-by-step explanation:
y = 1/4(x + 3)² + 2
To find the inverse, switch the places of the x and y.
x = 1/4(y + 3)² + 2
Solve for y.
x - 2 = (1/4(y + 3)² + 2) - 2
x - 2 = 1/4(y + 3)²
4(x - 2) = 4(1/4(y + 3)²)
4x - 8 = (y + 3)²
√(4x - 8) = √((y + 3)²)
√(4x - 8) = y + 3
√(4x - 8) - 3 = (y + 3) - 3
√(4x - 8) - 3 = y
y = √(4x - 8) - 3
Answer:
x ≤ - 5
Step-by-step explanation:
Given
- 2x - 1 ≥ 9 ( add 1 to both sides )
- 2x ≥ 10
Divide both sides by - 2, reversing the symbol as a result of dividing by a negative quantity.
x ≤ - 5
Answer:
x=26
Step-by-step explanation:
The sum of all angles in a triangle is equal to 180
x + 55 + (4x-5) = 180
Combine like terms
5x +50 = 180
Subtract 50 from each side
5x +50-50 = 180-50
5x = 130
Divide each side by 5
5x/5 =130/5
x =26
