Answer:
2(3x+y=4)
1(x+2y=-2)
6x+2y=8
<u>(-) x+2y=-2</u>
<u>5x=10</u>
5
x=2
x+2y=-1
2+2y=-1
<u>-</u><u>2</u><u> -</u><u>2</u>
<u>2y=-</u><u>3</u>
2
y=-3/2
Step-by-step explanation:
- multiply the first equation by 2 to make y equal to each other.
- subtract to eliminate y
- divide by 5 to get x
- take one of the equations
- replace x by 2 to solve for y
Answer: 24 km/h
Step-by-step explanation:
She traveled 18 km in 45 minutes, this could be simplified to .4 km/min or 24 km/h
Answer:
Price per carton * number of cartons
Step-by-step explanation:
dont have time to write it all here
The typical form of the slope intercept equation would be:
Y = mX + B
Where b is the y intercept, thus in thus case the y intercept would be 65 = (0,65).
Answer:
C
Step-by-step explanation:
f(x) = Price
2.00 = Price of one ride
x = number of times ridden
f(x) = 2x
