HELP PLSSSS I DONT UNDERSTAND WALLAH

Harlamova29_29 [7]

Answer:

7.2

Step-by-step explanation:

Distance between (4, 3) and (8, 9):

$d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

$d = \sqrt{(8 - 4)^2 + (9 - 3)^2}$

$d = \sqrt{(4)^2 + (6)^2}$

$d = \sqrt{16 + 36}$

$d = \sqrt{52} = 7.2$ (nearest tenth)

Curtis decided to go on a road trip to Canada. On the first day of his trip, he drove for 10 hours and traveled 640 miles. At wh

Elanso [62]

We can divide the amount he traveled (640) by the time he traveled (10):

640 / 10 = 64.

So Curtis drove 64 miles per hour.

Check:

64 miles per hour multiplied by 10 hours:

64 * 10 = 640

A bakery sells 7196 donuts in 2010. The bakery sells 9236 donuts in 2015. Write a linear model that represents the number y of d

-BARSIC- [3]

Answer:

$y=408x+7196$

Step-by-step explanation:

x is number of years after 2010

y is number of donuts

we are given

A bakery sells 7196 donuts in 2010

So, when x=0 , y=7196

Let's assume

$x_1=0,y_1=7196$

The bakery sells 9236 donuts in 2015

$x_2=5,y_1=9236$

now, we can find slope

$m=\frac{y_2-y_1}{x_2-x_1}$

we can plug values

$m=\frac{9236-7196}{5-0}$

$m=408$

now, we can use point slope form of line

$y-y_1=m(x-x_1)$

we can plug values

$y-7196=408(x-0)$

$y-7196=408(x-0)$

$y=408x+7196$
