Given the line below.

Grace [21]

Answer:

$y+2=(x+2)$

Step-by-step explanation:

The picture of the question in the attached figure

step 1

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have

(-2,-2) and (2,2)

substitute the values

$m=\frac{2+2}{2+2}=1$

step 2

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=1\\(x1,y1)=(-2,-2)$

substitute

$y-(-2)=(1)(x-(-2))$

$y+2=(x+2)$

PLS HELP The width of Ben's rectangular family

marin [14]

Answer:

19 feet

Step-by-step explanation:

The perimeter is calculated by multiplying the sum of length and width by 2

width is 3 less than length so if we call the width x the length would be x + 3

2×(x + x + 3) = 4x + 6 and

4x + 6 = 70 subtract 6 from both sides

4x = 64 divide both sides by 4

x = 16

The length is x + 3 so the answer is 19 feet

A bicyclist heads east at 10km/h. After she has traveled 24.2 kilometers, another cyclist sets out in the same direction going 3

Alona [7]

We know that the first cyclist has traveled 24.2 km at a speed of 10 km/h. Lets use the equation $time= \frac{distance}{speed}$ to find the time of the first cyclist:
$t= \frac{24.2}{10}$
$t=2.42$
So, we know that she has traveled for 2.42 hours.

We also know that after she has traveled for 2.42 hours another cyclist sets out in the same direction, so if $t$ represents the time of our first cyclist, the time of our second cyclist will be $t-2.42$ .

Now we are going to use the equation $distance=(speed)(time)$ to relate the speeds and times of the two cyclist:
For the first one:
$distance=10t$ equation (1)
For the second one:
$distance=30(t-2.42)$ equation (2)

Replace (1) in (2)
$10t=30(t-2.42)$
The only thing left now is solve for $t$ :
$10t=30t-72.6$
$-20t=-72.6$
$t= \frac{-72.6}{-20}$
$t=3.63$

We can conclude that the second cyclist will catch up the first cyclist after 3.63 hours.
