Answer:
thank you
Step-by-step explanation:
Answer: Well since the ratio is 9:7 for red to blue well transfer that first by finding out the blue if there are 117 xc=9:7x13 would be 117 red and 7x13=91 blue so the new ratio is 117:91.
So now we add which I'm sure you can do,
117
+
91

Standard form looks like this: Ax + By = C.
y - (-1) = 3(x - 4)
y + 1 = 3x - 12
y = 3x - 12 - 1
y = 3x + 13
Move 13 to left side and y to right side.
-13 = 3x - y
Done!
(2 / x-1)> (7 / x + 1)
For this case we can solve the problem graphically.
The solution will be the shaded region.
Note: see attached image.
