<h3>What is the slope-intercept form of a line?</h3>

The slope-intercept form of a line is y = mx +c where m is the slope of the line and c is the y-intercept.

The given equations are y = x +10 and y = x+5.

The equations are in the slope-intercept form of y = mx +b.

Therefore, the slopes of both lines are 1.

Two lines are parallel if they have the same slope.

Therefore, the graphs of the given equations are parallel.

7/8 = ?/48<br> A.13<br> B. 1<br> C. 42<br> D. 6
Ugo [173]

Hi Brainiac


7/8 =?/48

Let's replace the unknown place by x

7/8 = x/48

Cross multiply

(7)(48)= (X)(8)

336 = 8x

Flip it

8x = 336

Divide both sides by 8

8x/8 = 336/8

x= 42

The answer is C



Now if you wanna see if the answer is good just replace 42 in blank space

7/8 = 42/48

Now didivde 7 by 8 and divide 42 by 48

7/8= 0.875

42/48= 0.875


The answer C is correct


I hope that's help:)


If you have questions please let me know :)

What is the area of the white border?
Lina20 [59]

Answer:

A_{white} = 119\ cm^2

Step-by-step explanation:

<u>Step 1:  Determine the area of the black area</u>

A = l * w

A = 8\ cm * 2\ cm

A = 16\ cm^2

<u>Step 2:  Determine the area of the entire white and black area</u>

A = l * w

A = 9\ cm * 15\ cm

A = 135\ cm^2

<u>Step 3:  Determine the difference to just get the white area</u>

A_{white} = 135\ cm^2 - 16\ cm^2

A_{white} = 119\ cm^2

Answer: A_{white} = 119\ cm^2
