Z = 70 because 5x5 is 25 so u have to do 14x5 which is 70
I believe that x=9. I used cross multiplication. First, I multiplied 6 by 15. Second, I divided this product of 90 by 10. The quotient is 9.
F(x) = x^2 is a parabola with vertex at the origin (0,0).
f(x) = x^2 - 5 is a parabola shifted down 5 units so it's vertex would be at (0, -5)
The correct answer is Letter B
First step common denominator. (12) -5x2- 6x2- = 10/12 then -1x3- 4x3- =3/12
10 - 3 = 7/12 So 7/12 is ur answer
