Answer:
x=-5, y=-1
Step-by-step explanation:
Substitute x=-4+y into -2x-5y=15. So we have
-2(-4+y)-5y=15
8-2y-5y=15
-7y=7
y=-1
And x is -4+y so x= -4+(-1)= -5.
Answer:
Rotated 90° counterclockwise, then reflected across the y-axis
Step-by-step explanation:
Simple...
you have: 9u=10u-6
Isolate the variable-->>u
9u=10u-6
9u=10u-6
-10u -10u
-1u=-6
Now simply divide-->>
u=6
Thus, your answer.
