7% interest rate. He borrowed 4500 for two years. The total amount he had to pay additional in interest was 630. 4500x7% is $315. But since it was 2 years you would do 315x2 which equals 630 which was the amount he ended up paying additional for the two years.
Answer:
The system is composed of these two inequalities combined
y <= -x+4
y >= (1/3)x
-----------------------------------------------------------------------
Explanation:
The solid line has the boundary equation y = -x+4
This line goes through (0,4) and (4,0). Using the slope formula, we find that m = -1. Plugging m = -1 and (x,y) = (0,4) into y = mx+b leads to y = -x+4
The shading is below the solid line so we change the equal sign to a "less than or equal to" sign, which leads us to y <= -x+4
That takes care of the first inequality. We must use "or equal to" as part of the inequality to ensure the boundary is solid
------------
The second inequality is y > (1/3)x as the boundary line is y = (1/3)x. This line goes through (0,0) and (3,1). The slope is 1/3 and y intercept is 0
The boundary is a dashed line. This means we don't have "or equal to" as part of the inequality
