The number of stamps that kaye and alberto had were in the ratio 5 : 3, respectively. after kaye gave alberto 10 of her stamps,

Gala2k [10]

K:A
5:3 (before)
15:9

since the total number of stamps didn't change, the total ratio should be the same.

7:5(after)
14:10

so this means 1 unit is 10stamps.

14-10=4
4 X 10= 40

Kaye have 40 more stamps than Alberto.

Select the point that is a solution to the system of inequalities

ExtremeBDS [4]

<h3>Answer: B. (-1, 0)</h3>

This point is below both the red diagonal line and the blue parabola. We know that the set of solution points is below both due to the "less than" parts of each inequality sign.

In contrast, a point like (2,2) is above the parabola which is why it is not a solution. It does not make the inequality $y \le x^2-3x$ true. So this is why we can rule choice A out.

Choice C is not a solution because (4,1) does not make $y \le -x+3$ true. This point is not below the red diagonal line. We can cross choice C off the list.
