Answer:

y = 17x +128

Step-by-step explanation:

P1(-8,-8)

P2(-7,9)

Slope,

m = (y2-y1)/(x2-x1) = (9-(-8))/(-8-(-7)) = 17/(-1) = 17

The point-slope equation is

y-y1 = m(x+x1)

y-(-8) = 17(x-(-8))

y+8 = 17x + 136

y = 17x +128

4. I need help with question in the attached picture!

Arisa [49]

ANSWER

D. 13

EXPLANATION

We have

$f(x) = \frac{2x + 1}{x - 4}$

To find

${f}^{ - 1} (3)$

means we want to find an x-value whose image is 3.

$\frac{2x + 1}{x - 4} = 3$

We cross multiply,

$2x + 1 = 3(x - 4)$

Expand:

$2x + 1 = 3x - 12$

Combine like terms,

$3x - 2x = 12 + 1$

$x = 13$

$\therefore{f}^{ - 1} (3)= 13$
