Answer:
y = (x^2 + 6) / 2
Step-by-step explanation:
Original function: 
To find the inverse of a function we have to switch the x and y values and solve for y again
x = sqrt (2y-6)
To get rid of a square root we square the square root so:
x^2 = 2y-6
Add 6
x^2 + 6 = 2y
Divide by 2
y = (x^2 + 6) / 2
Answer:
(x²+5)(x+2)
simple find the common factor between x³ and 2x² and the cf of 5x and 10
u will end up with these results then^
Just substitute in the number 3 for x then subtract 3 at both sides and youll have y=7
To find the x intercept set y = 0
x^2 + x - 2 =0
(x+2)(x-1) = 0
x = -2 , x = 1
The equation of the area of the rectangle is w(2w + 5) = 50. Then the correct option is C.
<h3>What is a rectangle?</h3>
It has four sides and is a polygon. The internal angle adds up to 360 degrees. The opposite sides of a rectangle are parallel and equal, and each angle is 90 degrees. Its diagonals are equally equal, intersecting in the middle.
A rectangle’s length is 5 inches more than twice its width. its area is 50 square inches.
Let the width of the rectangle be w, then the length of the rectangle will be (2w + 5).
Then the area of the rectangle is given as
Area = l × w
Then we have
w(2w + 5) = 50
