This is (y2-y1)/(x2-x1), y2 being 12, y1 being 7, x2 being -39 and x1 being 26. So if you plug in the points it would be: (12-7)/(-39-26). This solved equals: -5/65 which simplified equals: -1/13
Answer:
x = -4
Step-by-step explanation:
put the quardinates in the slope formula and set it to 1/2 and solve by cross multiplying
9-7/x+8 = 1/2
2/x+8 = 1/2
4 = x+8
x = -4
Jenna has 3 red balloons and 5 blue balloons.
The ratio of the number of red balloons to the number of blue balloons is
3:5
She adds 2 red balloons and removes 1 blue balloon.
The new ratio of the number of red balloons to the number of blue balloons is
