Divide x2 - 9x +14 by x-2
You get x - 7

Check your work by multiplying x-2 and x-7
Since you get x2 - 9x +14,

x-7 is the answer.

Well, we can set up these equations like this-
Deborah- 2+3w
Kai- 12+2w
w=number of weeks that pass
Now, we set them equal to each other:
2+3w=12+2w

Solve for w
2-12=2w-3w
-10 = -1w
w = 10
10 weeks. Hope this helped!

Write an equation of the line with a slope of -3 and y-intercept of 0
klemol [59]

Answer:

y=-3x

Step-by-step explanation:

Slope intercept form is written as y=mx+b, where:

m= slope

b= y-intercept

We know the slope and y intercept already, so simply plug them in:

y=-3x+0

We can remove the +0 because it is redundant, therefore the final answer is:

y=-3x

Hey there! :)

Answer:

y = x - 3.

Step-by-step explanation:

Given:

Slope = 1

Point on line: (8, 5)

Plug these into the formula y = mx + b, where:

m = slope

x = x coordinate of point

y = y coordinate of point

5 = 1(8) + b

5 = 8 + b

Subtract both sides by 8:

5 - 8 = 8 -8 + b

-3 = b

Rewrite the equation:

y = x - 3.
