Answer:

A) $y+7=-3(x-4)$

Step-by-step explanation:

Hi there!

The given equations are written in point-slope form: $y-y_1=m(x-x_1)$ where m is the slope of the line and $(x_1,y_1)$ is a point that falls on the line

Notice how the line is travelling infinitely down as x increases. This means that the slope is negative.

Therefore, the equation of the line is either A or B.

Now, let's look at A:

$y+7=-3(x-4)$

This equation suggests that the point (4,-7) falls on the line, which it does.

Therefore, the equation of the graph is $y+7=-3(x-4)$ .

I hope this helps!

Solve the inequality and express your answer in interval notation x^2+8x-7<0

balandron [24]

Answer:

(-8.8, 0.8)

Step-by-step explanation:

x^2+8x-7<0
x^2 + 8x + 16 - 23 < 0
(x + 4)^2 < 23
|x + 4| < √23 ≈ 4.8

1 .

x + 4 < 4.8

x < 0.8

-(x + 4) < 4.8

x + 4 > - 4.8

x > - 8.8

Combination of the two intervals:

x = (-8.8, 0.8)
