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:
6
Step-by-step explanation:
The x-axis of point A is 3, multiplied by the scale factor of 2 equals 6. Which means the x-axis of point A' would be 6.
The answer would be = <span>10.3333333

Answer:
50
Step-by-step explanation:
add 5 to -25 to get -2/5x by itself.
Because the polynomial has degree 2, we can assume that there are 2 solutions (roots), whether real or imaginary.
You can subtract 60 in order to put this in standard form
48x^2+44x-60 = 0
From there, just put a,b, and c into the quadratic formula and you're good to solve for your answers.
(-b+-sqrt(b^2-4ac))/2a
(-44+-sqrt(44^2-4(48)(-60)))/2(48)
Then solve.
There is probably a better way, but this should give you the two roots/solutions.
