Answer:
Steve got 32 points
Step-by-step explanation:
Take the total score and multiply by the percentage received
40 * 80%
Change to decimal form
40 * .80
32
Steve got 32 points
5/12 is greater be side you have four more pieces compared to 1/12
- Reflection about the y-axis has rule (x,y)→(-x,y);
- Reflection about the x-axis has rule: (x,y)→(x,-y).
Consider rectangle ABCD and select, for example point A(-5,1).The set of reflections about the y-axis, x-axis, y-axis, x-axis will act on A in following way:
- about y-axis A(-5,1)→A'(5,1);
- about x-axis A'(5,1)→A''(5,-1);
- about y-axis A''(5,-1)→A'''(-5,-1);
- about x-axis A'''(-5,-1)→A(-5,1).
This reflections act on all rectangle vertices in the same way, then
the set of reflections that carry rectangle ABCD onto itself is
y-axis, x-axis, y-axis, x-axis
Answer:
A. No solution
Step-by-step explanation:
Pretty obvious! Subtract the second equation from the first and you will get...:
...a false equation! Thus, there is no solution for this system of equations.
