To solve this problem you must apply the proccedure shown below:
 1. You have the following quadratic equation given in the problem above:
  n²+4n-5; and you have one factor: <span> (n+5)
 2. Therefore, you must find a number whose sum with 5 be 4 and when their product be -5. Keeping this on mind, you have:
 (n+5)(n-1)
 3. To verify it, you can apply the distributive property:
 </span> (n+5)(n-1)=n²+4n-5
<span> The answer is: (n-1)</span>

picture included , please help, which of the following equations describe the line shown below (1,10) and (-3,2) *check all that
rosijanka [135]
Slope is\text{m}=\frac{y_1-y_2}{x_1-x_2}=\cfrac{10-2}{1-(-3)}
Then you use the equation
\text{y=mx+b}
Where b is the y-intercept. To find it, plug in x and y from one of the points. Say, point 1 (1,10):
10=m(1)+b
You know m (from above) and now you can solve for b.

Rearrange terms:
y-b=mx

And that will be the answer.

Make sense?
