Answer: so we have 5 positions, but we only care for the first two.

So, in the first position there are 5 options (because there are 5 swimmers).

In the second position whe will have 4 options (because there are already one swimmer in the first position).

So you have 5*4 = 20 ways for the prizes to be awarded.

It would be 20, because;
1 - 2 / 3 / 4 / 5
2 - 1 / 3 / 4 / 5
3 - 1 / 2 / 4 / 5
4 - 1 / 2 / 3 /5
5 - 1 / 2 / 3 / 4

= 4x5 = 20

Which point satisfies the system of equations y = 3x − 2 and y = -2x + 3?
Elodia [21]

Meet of lines: y = 3x − 2  and  y = -2x + 3?

y=3x-2 has slope 3 and y intercept -2 (which means thru (0,-2)) , so that's the blue line through point D.

y=-3x+3 has slope -2 and y intercept 3, so the red line through points A, C and  D.

The point D(1,1) is the intersection of the lines.  Let's check that algebraically:

3x-2=3(1)-2=1=y, good

-2x+3 = -2(1)+3=1=y, good

Answer: D
