0.5x + 1/5y -3.5x - 4/5 y
0.5x - 3.5x + 1/5 y - 4/5 y. Regroup f/ variable
-3.0x - 3/5 y
Answer: the answer is 4 decimal places and the second one is 10 to the power of 4 (10*4)
Step-by-step explanation:
Answer:
Slope=
and Y intercept=-3
Step-by-step explanation:
-2x + 6y = -18
Simplifying the equation,
6y = 2x - 18
A general line can be written as,
y=mx + c
, m= Slope of the line
c=y intercept of the line
Y intercept is basically the point where the line intersects, the y axis or the line x=0.
Therefore, from the above data m=
and Y intercept= -3.
So to start this question you find the prices of the two types of cups and create a basic formula for them. For the mug it would have a base price of $2.95 and a refill price of $0.50. For the disposable cup it would cost $0.85 a piece.
So for the mug you would take the base price of 2.95 and add it by x amount of refills to find the break even point of the two. So the formula would look like 2.95+0.50x. The other would be 0.85x. Now its just a matter of guess and check to see how many refills it would take for the mug to be cheaper. i hope this helped!
