3. Which property is represented by 5+ (-8)=-8 + 5? (1 po.

What is an equation for the linear function whose graph contains the points (9, 7) and (4, −8) ?

aalyn [17]

Y=mx+b where m=slope which is change in y divided by change in x m=(-8-7)/(4-9)=-15/-5=3 so we have y=3x+b now we can use either point, I'll use (9,7), to solve for b or the y-intercept... 7=3(9)+b 7=27+b b=-20so our line is: y=3x-20

Calculate the surface area and show work :) please help me no links!!

eimsori [14]

Answer:

294 in.²

Step-by-step explanation:

I believe this figure is a rectangular prism.

------------------------------------------------------------------------------------

<u>Explain:</u>

To find the surface area of a rectangular prism, use this formula:

$SA=2lw+2lh+2wh$

or

$SA=2(lw+lh+wh)$

$l-length$

$w-width$

$h-height$

A phrase I use to help remember this formula is:

LISA WILSON LOST HER WITCH HAT TWICE (2)

------------------------------------------------------------------------------------

<u>Solve:</u>

The length of this rectangular prism is 9 in.

This width is 10 in.

The height is 3 in.

Now, I will plug the numbers into the first formula.

$SA=(2*9*10)+(2*9*3)+(2*10*3)=294 in.^2$

------------------------------------------------------------------------------------

<u>Conclude:</u>

I, therefore, believe the area of this rectangular prism is 294 in.²

Ayesha ordered a bed set on 4th August, 2020. It was delivered to her house 9 months 2 weeks 4 days later. When was the bed set

astraxan [27]

Answer: I think it’s 22 May 2021

Step-by-step explanation:-

First Step ) August 2020 + 9 Months = May 2021

Second Step ) 4 + 7*2 ( two weeks has 14 days ) or 4 + 7 + 7 = 18

Third Step ) 18 + 4 Days Later = 22

So final answer would be 22 May 2021.

Hope it helps, Good Day! And happy reading

( P.S ) The bed set took a lot of time to arrive xD

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

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
