Hello I am not sure what it is but hopefully someone will help you
The solution(s) will be when the x and y coordinates are equal so we can say y=y or:
-x^2+x+1=-x+2
x^2-2x+1=0 now factor...
(x-1)^2=0
So the solution occurs when x=1, y(1)=-x+2=-1+2=1, so the solution is the point:
(1,1)
Answer: -3, -2/1 and negative
Step-by-step explanation:
y=mx+b
m is the slope and b is the y intercept
both of these are given
m=-2
b=-3
If you mark point (0,-3), your given y intercept, and use the given slope, -2, you can easily find your line, which declines going right.

Answer:
Step-by-step explanation:
If the square starts as n rows of n columns, adding another row of n columns will make a rectangle with dimensions n+1 rows by n columns.
__
The total number of tiles in the rectangle is said to be ...
n(n+1) = 2256
n^2 +n +1/4 = 2256 1/4 . . . complete the square
(n +1/2)^2 = (47 1/2)^2 . . . . rewrite as squares
n = 47
Answer:
6
Step-by-step explanation:
7x + 10 = 9x - 2
7x - 9x = -2 - 10
-2x = -12
-2x/-2 = -12/-2
x = 6
