A. Let x = cheese and
y = chocolate
2x + y = 25
x + y = 20
B. Subtract the second equation from the first.
2x + y = 25
-(x + y = 20)
-—————
x = 5
Plug 5 back in to the second equation and solve for y.
x + y = 20
5 + y = 20
Subtract 5 from both sides.
y = 15
5 cheese and 15 chocolate
Used elimination method because coefficients on the y values were both 1 so it was easy to subtract the equations and eliminate the y variable.
Answer:38
Step-by-step explanation:
triangle=3*1=3
decagon=10*1=10

Answer: A M (2,-3) and N ( 4,1)
Step-by-step explanation:
(-2, 3) after a 180 degrees rotation the coordinates will be in the fourth quadrant (2,-3) and the y coordinate is always negative in the fourth quadrant.
(-4,1) after a 180 degrees rotation the coordinates will be in the first quadrant (4,1) and all the coordinates will be positive.
Answer:
15) Slope (m) = -7/5
16) Slope (m) = 0
17) Slope (m) = 1/0 (It's an undefined slope, in other words it's just a vertical line)
