Answer:
(-2, 4)
Step-by-step explanation:
In the first equation substitute -2x for y, obtaining: 5x - 9(-2x) = -46
Then 5x + 18x = -46, or 23x = -46, resulting in x = -2
Since y = -2x, y = -2(-2) = 4
The solution is (-2, 4)
The car was towed for 48 miles.
Step-by-step explanation:
Given,
Amount charges by Acme towing = $30
Per mile charges = $3
Total charged = $174
Let, x be the number of miles.
Towing charges + Per mile charges*number of miles = Total charged
30+3x=174
Subtracting 30 from both sides
Dividing both sides by 3
The car was towed for 48 miles.

Step-by-step explanation:
Looking at the table, we can readily say that the correct
answer to this question is:
<span>
“With
increasing elapsed time, the amount of dissolved chlorine increases.”</span>
<span>
The
amount dissolved always increases with time unless it has already reached the
maximum limit. </span>
Answer:
The end behavior is As X Increases Y decreases and As X decreases Y increases.
Step-by-step explanation:
Since this is to the x power. This graph is going to be an exponential function. Meaning that It will look like a messed up L shaped. As you see in the graph, when the graph goes to the negative side of the X axis, the Y axis going up. As the X axis is above zero the Y axis is decreasing
