Write an equation in point-slope form of the line that passes through the point (

Scorpion4ik [409]

Answer:

Look below.

Step-by-step explanation:

Point slope fromula: y-y1=m(x-x1)

First we have to plug in our points and slope into the formula.

3 will be plugged into x1 while -1 will be plugged into y1.

Since m represents slope we will plug in -2 into m.

Answer: y+1=-2(x-3)

The length of a rectangle is 8cm more than 3 times it’s width. The perimeter of the rectangle is 64cm

FinnZ [79.3K]

Answer:

<em>The length is 26 cm, and the width is 6 cm.</em>

Step-by-step explanation:

The width is unknown. Let w = width.

The length is 8 cm more than 3 times the width.

length = 3w + 8

The perimeter is 64 cm.

P = length + length + width + width

3w + 8 + 3w + 8 + w + w = 64

8w + 16 = 64

8w = 48

w = 6

The width is 6 cm.

length = 3w + 8 = 3(6) + 8 = 18 + 8 = 26

The length is 26 cm

D=vit + at<br> solve for vi

gavmur [86]

Answer:

$\large\boxed{vi=\dfrac{d-at}{t}}$

Step-by-step explanation:

$d=vit+at\qquad\text{subtract}\ at\ \text{from both sides}\\\\d-at=vit+at-at\\\\d-at=vit\qquad\text{divide obth sides by}\ t\\\\\dfrac{d-at}{t}=\dfrac{vit}{t}\\\\\dfrac{d-at}{t}=vi$
