Answer:

7.2 units

Step-by-step explanation:

$d=\sqrt{(x_{2}-x_{1})^2 + (y_{2}- y_{1})^2 } \\d= \sqrt{(-4+8)^2 + (-5-1)^2} \\d= \sqrt{4^2 + (-6)^2} \\d=\sqrt{16+36} \\d=\sqrt{52} \\d=7.22$

Maya drove to the mountains last weekend. There was heavy traffic on the way there, and the trip took 12 hours. When Maya drove

Roman55 [17]

Answer:

480 miles.

Step-by-step explanation:

Let x represent the distance between Maria's house and mountains ans r represent Maria's rate for going trip.

We have been given that there was heavy traffic on the way there, and the trip took 12 hours.

$\text{Distance}=\text{Rate}\times \text{Time}$

$x=12r$

We are also told that hen Maya drove home, there was no traffic and the trip only took 8 hours. Maria's average rate was 20 miles per hour faster on the trip home.

So Maria's speed while returning back would be $r+20$ .

$x=8(r+20)$

Upon equating both distances, we will get:

$12r=8(r+20)$

$12r=8r+160$

$12r-8r=8r-8r+160$

$4r=160$

$r=\frac{160}{4}$

$r=40$

Upon substituting $r=40$ in equation $x=12r$ , we will get:

$x=12r\\\\x=12(40)\\\\x=480$

Therefore, Maya live 480 miles away from the mountains.

Each statement describes a transformation of the graph of y = x. Which statement correctly describes the graph of y = x + 7? A.

rosijanka [135]

<h3>Answer: choice A, graph is moved 7 units up</h3>

The plus 7 at the end will shift the graph 7 units up. Replace y with f(x).

Then we have g(x) = f(x) + 7. Adding 7 to y = f(x) will increase the y value by 7.
