Answer 2

The last three I didn't understand as well @sarahhmariee

Answer 3

@BunnyBree

Answer 4

1. x + 15 = 8
-15 -15
x = -7 Number one is correct. (:

2. 15 – z = 6
-15 -15
-z = -9
z = 9 <-- This is the correct answer.

3. 6x = –42
6x/6 = –42/6
x = -7 You're correct! :D

I think four and five may be missing some information.

Answer 5

ohh sorry

Question 5.5. What is the slope of a line parallel to the line whose equation is 5x + 3y = 15?
A: -5/3
B: -3/5
C: 3/5
D: 5/3

Answer 8

This is the missing information @BunnyBree :)

Answer 25

Okay, sorry! Was interrupted by other questions. xD
Alright, so we need to use the slope formula for four. m = y2 - y1/x2 - x1
Plugging the points in and solving, we get -5/4. You were close with number four. :D

Question 5: Parallel lines have the same slope. 5x + 3y = 15 is in standard form however, and it's easier to convert it to slope intercept form to find the slope.
5x + 3y = 15
- 5x -5x
3y = -5x + 15
3y/3 = -5x/3 + 15/3
y = -5/3x + 5
Slope is -5/3x. So, the answer is A.

Answer 26

There is nothing to solve on #5

Answer 27

@iLorita , lets do #10 ok?

Answer 28

I put the questions for 4 and 5 @JordanTheGirl @sleepyjess

Answer 29

I got that answer but I thought I was wrong xD @BunnyBree

Answer 30

Ok @sleepyjess

Answer 31

Yes, but I don't see the answers for 4 and 5

Answer 32

Go back up see if you can see it.I cant.I wish I still had work like this.Now it is harder.

Answer 33

So, what 10 is basically saying is that \(\sf\dfrac{82.5+94.7+87.9+x}{4}=90\) and we need to solve for x

Answer 34

Question 4.4. What is the slope of the line that passes through the points (1, 3) and (5, –2)?
A: 5/4
B: -5/4
C: 4/5
D: - 4/5

@sleepyjess

Answer 35

so it would be 265.1x/4 right? @sleepyjess

Answer 36

My answer isn't I one of the choices @sleepyness
