(-3x+3y=-9)-(-3x+y=7)
-3x+3x+3y-y=-9-7
2y=-16
y=-8, making -3x+3y=-9 become:
-3x+3(-8)=-9
-3x-24=-9
-3x=15
x=-5
So the solution to this system of equations is the point (-5, -8)
Answer:
Step-by-step explanation:
Because we know x stays constant, draw a point on (0,5). then draw a line extending up and down from (0,5) indefinitely because no matter what y is, x always stays the same--5.
Answer:
8
Step-by-step explanation:
a² = 10² - 6²
a² = 100 - 36
a² = 64
a = √64
a = <u>8</u>
So, the value of a is 8
