A very good estimate of 48% of 60 is 30, since 48% is almost half of a number, and 30 is half of 60. When you 60 * 0.48, the real answer is 28.8.

Explanation:</h2><h3>Part A.</h3>
The boundary lines of both inequalities will be dashed, because neither includes the "or equal to" case.
The first inequality solution area is bounded by a line with slope +5 and y-intercept +5. The solution area is above the line (y is greater than ...). Since the line rises steeply, the solution area looks to be to the left of the line. (It is shaded red on the attached graph.)
The second inequality solution area is bounded by a line with slope -1/2 and y-intercept +1. The solution area for this inequality is also above the line.
The solution area is where the two solution spaces overlap, in the quadrant to the upper left of the point where the lines intersect.

<h3>Part B.</h3>
The graph shows the point (-2, 5) to be in the solution space.
We can show this point satisfies both inequalities.
- 5 > 5(-2)+5 ⇒ 5 > -5 . . . true
- 5 > (-1/2)(-2) +1 ⇒ 5 > 2 . . . true
I'm pretty sure this is correct if so hope it helped:)
Answer:
5
Step-by-step explanation:
slope: increase in y ÷ increase in x
slope: (45-15)÷(9-3)
slope: 30÷6
slope: 5
