Saying "a number" is the same as saying "x"

"Three more than a number" is the same as "three more than x"

If you have three more of something (say, marbles) than someone else, then you have their number of marbles plus three more.

Then, "Three more than x" is the same as "three plus x", or "3 + x"

Hope this helps! :)

Watch this carefully, before it's gone:

The expression for " three more than 'x' " is . . . . . <em>( x + 3 )</em>  .

Did you see it go by ?
Here it is again:

The expression for " three more than 'x' " is . . . . . <em>( x + 3 )</em>  .

Find the equation of the line passing through the points (5,21) and (-5,-29)
Assoli18 [71]

Answer:

Look below

Step-by-step explanation:

lets have -29 be y2 and -5 be x2

21 - (-)29

5 - (-)5

Subtracting a negative is just adding it so

21 + 29   50
5 + 5       10

50/10

this simplified, is 5/1 or 5

y=5x+b

now we need to find b, so we substitute  y and y

x = 5

y = 21

21=5*5=b

5*5 is 25

now we need to get to 21


25 -4 is 21

b = -4

y=5x-4
