Answer:
x=1, y=-1. (1, -1)
Step-by-step explanation:
2x-3y=5
x+2y=-1
---------------
2x-3y=5
-2(x+2y)=-2(-1)
-----------------------
2x-3y=5
-2x-4y=2
-------------
-7y=7
y=7/-7
y=-1
x+2(-1)=-1
x-2=-1
x=-1+2
x=1
6.59 written as a fraction would either be 659/100 or 6 59/100
B because when you reflect over the y axis, the y value stays the same but the x value changes to the opposite of what it was before (for example, the value of x was 8 but when you reflect over the y axis, it changes to -8)
Sum of infinite series of a GS is a1 / (1-r)
so here it is 65 / (1 - 1/6) = 65 / 5/6 = 65*6 / 5 = 78 answer
Answer: (5, 12)
Step-by-step explanation:
Just graph the linear equations and find where they intersect.
Algebraically, you can set them equal to each other
-3x-3=2x+2
-x-3=2
-x=5
x=5
Plug x=5 to any equation
y=2(5)+2
y=12
