Answer:
x=6,-4
Step-by-step explanation:
Ok so we know the 2 angles are congruent so you need to set them equal to each other. x^2+5x=7x+24. Then get the x's together so you subtract by 7x to get x^2-2x=24. You would then get 24 on the other side so subtract by 24 to get x^2-2x-24. You then would need to factor the equation out. The factored form would be (x-6)(x+4). Then set it equal to 0 to get 6 and -4.

Answer:
3rd option
Step-by-step explanation:
the denominator cannot be zero as this would make the expression undefined.
equating the denominator to zero and solving gives the values that x cannot be.
x² - 7x - 18 = 0 ← in standard form
(x - 9)(x + 2) = 0 ← in factored form
equate each factor to zero and solve for x
x - 9 = 0 ⇒ x = 9
x + 2 = 0 ⇒ x = - 2
then
x = - 2, x = 9 ← are the excluded values
F-1(x)=x/4 represents the inverse function because to find the inverse you have to interchange the variables & solve for y
