Answer:
No mistake
Step-by-step explanation:
2x + y = 5
x - 2y = 10
y = 5 - 2x
x - 2(5 - 2x) = 10
x - 10 + 4x = 10
5x - 10 = 10
5x = 20
x = 4
2(4) + y = 5
y = -3
She made no mistake
You can check by plugging in x = 4 and y = -3 into the original equations . They fit exactly.
<h3>
Answer: C. x+y = 4</h3>
This is the line through points A and C, which is one of the diagonals. Reflecting any square over its diagonal will result in the same figure. We can say it's symmetrical about the diagonal line.
Put another way, reflecting point B over the line x+y = 4 will have it land on point D. Then point D will move to where B used to reside. In short, points B and D swap places. Points A and C will stay fixed in place.

Correct it is right u have to multipl
Answer:8.4
Step-by-step explanation:
Ten percent of 14 is 1.4 so add 1.4 4 times or multiple 1.4 by 4 and you get 5.6, then subtract 14 by 5.6 and you get 8.4
