Answer:

D

Step-by-step explanation:

There's no solution because they are not touching each other. If they intersected at one point there would b one solution and if one is exactly on top of another there's infinity solutions which looks like only one line.

*1 A car is driving away from a crosswalk. The distance d (in feet) of the car from the crosswalk t
antoniya [11.8K]

Answer:

The change in the car's distance is 8 feet

Step-by-step explanation:

* Lets explain how to solve the problem

- A car is driving away from a crosswalk

- The distance d (in feet) of the car from the crosswalk t  seconds

  since the car started moving is given by the formula d = t² + 3.5

- The time increasing from 1 second to 3 seconds

- We need to now the change of the car's distance from the crosswalk

∵ The equation of the distance is d = t² + 3.5

∵ The time is 1 second

∴ d = (1)² + 3.5

∴ d = 1 + 3.5 = 4.5 feet

∵ The time is 3 seconds

∴ d = (3)² + 3.5

∴ d = 9 + 3.5 = 12.5 feet

∵ The change of the distance = d of 3 sec - d of 1 sec

∵ d of 3 sec = 12.5 feet

∵ d of 1 sec = 4.5 feet

∴ The change of the distance = 12.5 - 4.5 = 8 feet

∴ The change in the car's distance is 8 feet

Determine the slope Of a line perpendicular to the line with equation 6x-4y=30
trasher [3.6K]
First, simplify the equation into y=mx+b form. This would be y=3x/2-15/2. And for the slope of a line perpendicular to the original line, there is a trick. Their slopes should multiply to -1. For 3/2 to multiply to -1, you need -2/3.

A section of a railway has a slope of approximately 0.37. In this section, a vertical change of one unit corresponds to a horizo
Sedaia [141]
Slope \frac{dy}{dx}=0.37

We are given dy=1
So \frac{1}{dx}=0.37
⇒dx=\frac{1}{0.37}≈2.70
