y=-2x+8
y=x-1
Solve y=-2x+8 for y
Substitute -2x+8 for y in y =x-1
y=x-1
-2x+8=x-1
Add -x to both sides
-2x+8+-x=x-1+-x
-3x+8=1
Add -8 to both sides
-3x+8+-8=1+-8
-3x=-9
Divide both sides by -3
-3x/-3=-9/-3
x=3
Substitute 3 for x in y =-2x+8
y=-2x+8
y=(-2)(3)+8
Simplify both sides of the equation
y=2
Answer : y=2 and x=3
(3,2)

Answer: -6(n - 3) = 18, n = 0
Step-by-step explanation:
The equation "The difference between a number and three is multiplied by negative six. The result is eighteen." can be expressed as -6(n - 3) = 18. To find n, you solve algebraically to get n = 0.
I hope this helps!
Answer: 2*2=4
Step-by-step explanation:
The reason that it is equal to four is because the exponent is two and you multiply the base(2) by itself the amount of times that there is a exponent. So for this problem you would multiply 2 by itself 2 times. (2*2=4)
this means
from x<-2 only graph y=3 but not -2
from -2<=x<2 only graph -x/2+2 but not 2
from x>=2 only graph 2x-3 including 2
the closest graph is the first but its has a mistake, on the middle graph the circle should not be shaded in

b>-2
Final answer:
b<4 or b>-2 </span></span>
