Answer:
step 1. y - y1 = m(x - x1). This is the standard line equation given a point and a slope.
step 2. parallel lines have the same slope so the slope is -4.
step 3. y - (-5) = -4(x - (-4)).
step 4. y + 5 = -4x - 16.
step 5. y = -4x - 21.
Answer:
The cost must be $32 since that is the only cost possible for the 1st deal
Step-by-step explanation:
Let C represent the total cost of each deal
Let T be the number of trips down the water slide
C = 32 for the 1st deal since the cost is the same regardless of how much she rides
C = 18 + T for the 2nd deal
To find when the two costs are equal set them equal to each other and solve for T
32 = 18 + T
T = 14 trips
The cost must be $32 since that is the only cost possible for the 1st deal

Answer:
I think that will be 2.7
Step-by-step explanation:
i did 5x^3 x 3/10x^-5
-5x -5x
and then you get 3/5x^-2(i got -2 because I did 3+-5)
x= 2.7
