Answer:
x = -3, y = 2
Step-by-step explanation:
x - y = -5
x = -5 + y
Let's put this into the other equation
(-5 + y) + y = -1
-5 + 2y = -1
2y = 4
y = 2
Now we can solve for x by plugging y into either equation
x + (2) = -1
x = -3
The problem ask to choose among the following functions in the given choices that has the greatest value and the best answer among the following function is letter D. a linear function that goes through point 2,0 and point 0,2. I hope you are satisfied with my answer

translate down by 4:
(5,3)
reflect over y (so invert x-coordinate):
(-5,3)

Answer:
x = 2
Step-by-step explanation:
log27(x + 7) - log27(x - 1) = ⅔
log27[(x + 7)/(x - 1)] = ⅔
(x + 7)/(x - 1) = 27^⅔
(x + 7)/(x - 1) = 9
x + 7 = 9(x - 1)
x + 7 = 9x - 9
8x = 16
x = 2
