Answer:
3/4
Step-by-step explanation:
We can find the slope using the slope formula
m = (y2-y1)/(x2-x1)
= (5-2)/(7-3)
=3/4

Answer:
Excluded values are any given number(s) that can make an expression's denominator zero.
First you set the denominator equal to zero, like so:
(x-1)(x+7) = 0
Now you can see if you make each (x-1) and (x+7) equal to zero:
<u>x-1=0 x=1</u>
<u>x+7= x=-7</u>
Excluded values:
From my understanding 1 and -7 would be the excluded values.
Answer:
4f^2 - r^2 + 3r
Step-by-step explanation:
(4f^2 + 6r + 3) - (r^2 + 3r + 3)
Distribute
4f^2 + 6r + 3 - r^2 - 3r - 3
subtract +3 from -3
4f^2 + 6r - r^2 - 3r
combine like terms
4f^2 + 3r - r^2
rearrange terms
4f^2 - r^2 + 3r
