Answer:

-14

Step-by-step explanation:

$f(x) = -4x – 7 \\ plug \: x = - 1 \\ f( - 1) = - 4( - 1) - 7 = 4 - 7 = - 3 \\g(x) = x² + 7x – 2 \\g(f( - 1)) = {( - 3)}^{2} + 7( - 3) - 2 \\ = 9 - 21 - 2 \\= - 14$

Quick algebra 1 questions for 50 points!

Semenov [28]

The answer to this question is:

D. The y intercept is 52, and if Jordan does not use any gigabytes of data then his charge is $52

It’s in the y = mx + b form

The 52 is in the b area, which stands for the y intercept while the number with a variable is the rate.

How do I do this while I show all my work?

One way to determine the slope of a line is from two points on a line.

We can use the ones already indicated on the graph, (0,4) and (3,5).

The slope is change in y divided by change in x,

$m= \dfrac{5 - 4}{3 - 0} = \dfrac 1 3$
