Write an equation in slope-intercept form for the line that passes through (4, 7) and is perpendicular to the y-axis. Is the answer y=2x+3 ??

y = -1/2x + 9

Step-by-step explanation:

y - 7 = -1/2(x - 4)

y - 7 = -1/2x + 2

y = -1/2x + 2 + 7

y = -1/2x + 9

really really sorry if i'm

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
