m = (y2 - y1)/(x2 - x1)

m =(220 - 100)/(3 - 0)

m = 120/3

m = 40

Hope this helps!

Risa is sewing a ribbon around the sides of a square blanket.each side of the blanket is 72 inches long.how many inches of ribbo
Tanzania [10]
<span><span /><span>In this problem, we are looking for the total inches of ribbon that Risa needed in order to complete sewing all sides of the Blanket.

She needs 72 inches per sides of the blanket.
A blanket is consisting of 4 sides, therefore multiply 72 by 4.
=> 72 x 4
=> 288 inches
or simply add 4 72s
=> 72 + 72 + 72 + 72
=> 288 inches</span></span>

The point-slope form of the equation of the line that passes through (–9, –2) and (1, 3) is y – 3 = (x – 1). What is the slope-i
bulgar [2K]
(-9,-2) (1,3)
slope = (3 - (-2) / (1 - (-9) = 5/10 = 1/2

y - y1 = m(x - x1)
slope(m) = 1/2
(1,3)...x1 = 1 and y1 = 3
sub
y - 3 = 1/2(x - 1)
y - 3 = 1/2x - 1/2
y = 1/2x - 1/2 + 3
y = 1/2x - 1/2 + 6/2
y = 1/2x + 5/2 <=== slope intercept form

To frame two problems of linear equation in one variable of your choice and solve such that the result of the first problem shou
AVprozaik [17]

Answer:

x + y = 79 and

x - y = 25

(x,y) = (52,27)

Step-by-step explanation:

Let the variables be: x and y

The equations can be modelled as:

x + y = 79 and

x - y = 25

To solve for x and y, we have:

Make x the subject in x - y = 25

x = 25 + y

Substitute x = 25 + y in x + y = 79

25 + y + y = 79

25 + 2y = 79

Collect like terms

2y = 79 - 25

2y = 54

Divide both sides by 2

y = 27

Substitute y = 27 in x = 25 + y

x = 25 + 27

x = 52

So, we have:

(x,y) = (52,27)

In a certain year, the average e-mail user sent or received 114 e-mails each day. The number of e-mails received was 6 more then
Tems11 [23]

Answer:

78 emails

Step-by-step explanation:

Given

Represent sent emails with x and received with y.

So, we have:

x + y = 114 -- First statement

y = 6 + 2x -- Second statement

Required

Determine the number of emails received (y)

Make x the subject in x + y = 114

x = 114 - y

Substitute 114 - y for x in y = 6 + 2x

y = 6 + 2(114 - y)

Open bracket

y = 6 + 228 - 2y

Collect Like Terms

2y+y = 6 + 228

3y = 234

Divide by 3

y = 234/3

y = 78
