X + y = 33
x - y = 9 Add the 2 equations together
---------------
2x = 42 Divide both sides by 2
x = 21
Use the original equation and plug 21 in for x, then solve.
x + y = 33
21 + y = 33
Subtract 21 from both sides
y = 12
One list had 21 items on it and the other list had 12 items on it.
Answer:
The scale factor of this dilation is 1/2
Step-by-step explanation:
Answer: slope is 9, y intercept is -3 or the coordinate (0,-3)
Step-by-step explanation:
y=Mx+b
M is the slope
B is the y intercept
160/3 is 53 1/3 as a fraction
33 1/3 because it if you times it by 3, you get 100
