Write the equation of a line that is parallel to y = -5/4x+ + 7 and that passes through the point (-4,1).
k0ka [10]

Answer: y- 1 = -5/4(x+4)\\

Step-by-step explanation:

y = mx + b, where m is the slope, and in the equation, the slope is -5/4.

For two-line that are parallel, the slope is the same, -5/4.

y - y_{1}= m( x - x_{1})\\y- 1 = -5/4(x-(-4))\\y- 1 = -5/4(x+4)\\

miv72 [106K]

Answer:

150 seconds

Step-by-step explanation:

use the velocity equation of

V=\frac{delta(D)}{Delta(T)\\}

Where V is in feet per second, Delta D represents the change in displacement and delta t represents the change in time

all you need to do is rearrange the equation to find Delta(T)

as such...

Delta(t)*V=Delta(D)\\Delta (t)=\frac{Delta(D)}{V}\\Then\ insert\ your\ corresponding\ values\\\Delta(t)=\frac{270 ft}{1.8 feet/sec}  \\Delta (t)= 150sec
