there is an equation for straight lines which goes

y-y,=m(x-x,)

where( x, , y, ) is any coordinate on the line and m is the gradient

so your answer is

y-7= -2(x-4)

does this make sense?

It would go -2 then the remaining number. I understand I just recently got done with this type of math, it’s a pain.

What number can go into 2470,121 and 45<br>

Usimov [2.4K]

Answer:

Step-by-step explanation:

All of these numbers can be divided by 2, 3, 5, 7, 11, 13...

There is no whole number if you want to divide each number.

121 only goes into 1, 11, and 121. No other numbers have 11

45/2 = 22.5

45/3 = 15

45/5 = 9

2470/2 = 1235

2470/3 = 823.33333...

2470/5 = 494

121/2 = 60.5

121/3 = 40.33333...

121/5 = 24.2

Fine the equation, in standard form, of the line passing through the points (3,-4) and (5,1)

Talja [164]

The point-slope form:

$y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (3, -4) and (5, 1). Substitute:

$m=\dfrac{1-(-4)}{5-3}=\dfrac{5}{2}\\\\y-(-4)=\dfrac{5}{2}(x-3)$

The standard form: $Ax+By=C$

$y+4=\dfrac{5}{2}(x-3)$ <em>multiply both sides by 2</em>

$2y+8=5(x+3)$ <em>use distributive property</em>

$2y+8=5x+15$ <em>subtract 2y from both sides</em>

$8=5x-2y+15$ <em>subtract 15 from both sides</em>

$-7=5x-2y$

<h3>Answer: 5x - 2y = -7</h3>

Ashley arranged the following list of numbers below: 5,2,7,8,2,5,3. Find the mean and median.

jok3333 [9.3K]

Mean is the average of all numbers

(5+2+7+8+2+5+3)/7

Mean is 4.57

Median is the middle score so we have to arrange all the numbers from lowest to highest

2, 2, 3, 5, 5, 7, 8

Median is 5

Brian works 40 hours a week. He spends 40% of his time helping customers, 13% doing paperwork, and the remainder performing othe

MissTica

40% helping customers + 13% doing paper work = 53% of his time.

This means 100% - 53% = 47% of his time he is doing other tasks.
