Aaron solved an inequality and then graphed the solution as shown below.
1 answer:
The inequality solved by Aaron is (a) |x + 2| < 3
<h3>How to determine the inequality?</h3>The attached graph represents the missing piece in the question.
From the graph, we can see that:
The value of x starts from -5 and ends at 1
Calculate the mean of these values
Mean = (1 - 5)/2 = -2
Calculate half the difference of these values
Difference = (1 + 5)/2 = 3
The inequality is then represented as:
|x - Mean| < Difference
This gives
|x + 2| < 3
Hence, the inequality solved by Aaron is (a) |x + 2| < 3

Answer:
Jenny save 4 times for the month
Step-by-step explanation:
Given Jenny has saved over the last 12 months.
She saved either or
a month.
Let the number of months to save be x
Let the number of months to save be y
Total period is 12 month.
Jenny has saved $3,800 over the last 12 months.
Dividing both side from 50 we get,
Now Multiplying equation 1 by 5 we get,
Now Subtracting Equation 3 by equation 2 we get,
Substituting the value of y in equation 1 we get,
∴ Jenny save 4 Months of and 8 Months of
in a 12 month duration
