Answer:
2x - 12
Step-by-step explanation:
Answer:
(6, -2)
Step-by-step explanation:
The midpoint of the segment RS is point M (5, 3). Therefore, the average of the x coordinates of R and S is 5, and the average of the y coordinates of R and S is 3. The x coordinate of R is 4. For 4 and the x coordinate of S to have an average of 5, the x coordinate of S must be 6. Therefore, our point is of the form (6, y). For 8 and the y coordinate of S to have an average of 3, the y coordinate of S must be -2. Therefore, our answer is (6, -2)
Answer:
x=-3, y=-7. (-3, -7).
Step-by-step explanation:
x-5y=32
2x-9y=57
---------------
x=5y+32
2(5y+32)-9y=57
10y+64-9y=57
10y-9y=57-64
y=-7
x-5(-7)=32
x+35=32
x=32-35
x=-3
