Answer:
x^2+3x-18
Step-by-step explanation: hoped I helped
Answer:
Free points?!?
Step-by-step explanation:
Just matter of combining like terms
6x - 7 - 11x + x =
(6x + x - 11x) - 7 =
(7x - 11x) - 7 =
- 4x - 7 <===
Once we find what x and y is, that's where they intercept and we can write that as an ordered pair as (x,y)
Now we need to find what y is. So let's put x into the original first equation
3x+4y=16
3(4)+4y=16
12+4y=16 ---Subtract 12 from both sides
4y=4 ---Divide both sides by 4
y=1
Alright, so our ordered pair is (4,1)
Answer:

Step-by-step explanation:
Point-slope is:


<h2>
Our goal: </h2>
We have to complete the point-slope equation of the line through (1,3) (5,1).
--------------------------------------------------------
We have a incomplete equation of the line.

We need to find the <u>slope</u> of the line, and the <u>value</u> of
.
--------------------------------------------------------
<h3>Finding 'x1':</h3>
It seems that the value of 3 was used to be
. This means that the point
was used for the equation. This means that
would have to be 1.
<h3>Finding Slope:</h3>
Slope is rise over run.

We are given the points (1,3) and (5,1).

The slope is one-half.
--------------------------------------------------------
We now have enough information to complete the point-slope equation.

Our final equation is:
