I need help on this on my bros

Use the inverse of the function y=x^2-18x to find the unknown value [tex]y = \sqrt{bx + c \: + d} [/tex]

Line gh passes through points (2, 5) and (6, 9). which equation represents line gh? y = x + 3 y = x – 3 y = 3x + 3 y = 3x – 3

What value of x is in the solution set of 4x - 12 s 16 + 8x? -10 -9 -8 -7
