Find the distance between (-3,-1) and (4, 2). (Round up to the nearest hundredths.)
yanalaym [24]

Answer:

The answer is

<h2>7.61 units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

<h3>d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  }  \\</h3>

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-3,-1) and (4, 2).

The distance is

d =  \sqrt{ ({ -  3 - 4})^{2}  +  ({ - 1 - 2})^{2} }  \\  =  \sqrt{ ({  - 7})^{2}  +  ({ -   3 })^{2} }  \\  =  \sqrt{49 + 9}  \\  =  \sqrt{58}  \\  = 7.615773

We have the final answer as

<h3>7.61 units to the nearest hundredth</h3>

Hope this helps you

A grocery store has small bags of apples for 5$ and large bags of apples for 8$. If you buy 6 bags of apples and spend 45$, how
pogonyaev

Answer:

He bought 1 small bag and 6 large bags.

Step-by-step explanation:

We can set up 2 equations with the given information.

5x+8y=45

x+y=6

We can rearrange the second equation to solve for x.

x=6-y

Now we substitute x for 6-y in the first equation

5(6-y)+8y=45

30-5y+8y=45

30+3y=45

y+10=15

y=5

x=1

He bought 1 small bag and 6 large bags.
