Answer:

8) No solution

9) n > -5 <em>(View explanation for info on how to graph)</em>

Step-by-step explanation:

<em><u>Question 8</u></em>

<em><u /></em>

<u>24+6k < -6(-4-k)</u> - Solve and graph

1) Distribute -6 to -4 and -k:

24+6k < 24+6k

2) Subtract 6k from both sides:

24<24

^ We know the following is false, therefore there is no solution to question 8.

<em><u>Question 9</u></em>

<em><u /></em>

<u>-2n-40 < 5(6+n)+7n</u> - Solve and graph

1) Distribute 5 to 6 and n:

-2n-40 < 30+5n+7n

2) Combine alike terms:

-2n-40 < 30+12n

3) Add 2n to both sides:

-40 < 30+14n

4) Subtract 30 from both sides:

-70 < 14n

5) Divide both sides by 14:

n > -5

6) To graph, plot an OPEN CIRCLE (<em>don't fill in the circle)</em> at point -5 and then draw an arrow pointing to the right!

Let me know if you need any help with the others :)

What is the slope-intercept form of the equation of the line with the slope of -5/8 that passes through the point (-14,6)
inessss [21]

Step-by-step explanation:

y-y1 = m(x-x1) is the equation for a linear line in y=mx+b (slope intercept)

slope = m = -5/8

x1 = -14

y1 = 6

y-6 = -5/8 (x--14)

y-6 = -5/8 (x+14)

y-6 = -5/8x-70/8

y-48/8= -5/8x-70/8

y = -5/8x - 22/8

When x = 0, y = -22/8, which makes (0, -22/8) your y intercept
