Explanation:
The expression is given below as

Concept:
We will apply the bsolute rule below

By applying the concept, we will have

Hence,
The final answer is
Answer:
We can conclude that someone used more tiles then the other because both equations are not equal.
Step-by-step explanation:
If you try to solve it both equations will not be shown as equal.
I believe the answer is D.
No, it is not a proportional relationship because the graph does not go through the origin.
Answer:
-5/3
Step-by-step explanation:
Parallel lines are lines which have the exact same slope but different y-intercepts. We can find the slope by converting to slope-intercept form, y=mx+b from standard form.
We convert by using inverse operations to isolate y.
5x+3y=7
5x-5x+3y=7-5x
0x+3y=-5x+7
3y=-5x+7
.
The slope is -5/3. SInce parallel lines have the same slope, the slope for a parallel line will be -5/3.
