Answer:
(-2,-1) WHen rotating it 180 counterclockwise it will be (-x,-y)
Answer:
x = -2 and y = -3
Step-by-step explanation:
It is given that,
-8x + 3y =7 ----(1)
13x - 3y =-17 -----(2)
<u>To find the value of x and y</u>
eq(1) + eq(2) ⇒
-8x + 3y = 7 ----(1)
<u> 13x - 3y = -17 -----(2)</u>
5x + = -10
x = -10/5 = -2
Substitute value of x in eq (1)
-8x + 3y =7 ----(1)
-8 * -2 + 3y = 7
16 + 3y = 7
3y = 7 - 16 = -9
y = -9/3 = -3
Therefore x = -2 and y = -3
He was 21 in 1980,
There are twelve years in between them all so you subtract 36 from 78 and since he was double as old as Nancy, and Manual was the same age as her, you would divide 42 into two parts, Ric and the 10.5 year olds, and Ric would be 21 in 1980.
The answer for this one is 3/11.

For this case we must add the terms of the following expression:
It is noted that the terms are similar, so we can add:
We take common factor
We add the terms within the parenthesis:
finally we have:
