Answer:
10x+5
Step-by-step explanation:
You would add 3x and 7x
you would leave 5 alone because it has no x thus it can not be added to the 3x and 7x
Answer:

Step-by-step explanation:
Slope intercept form is
where <em>m </em>is the slope and <em>b </em>is the y-intercept.
Slope is
or
in this case = 
Substitute one of the coordinates for x and y. I am going to use (0, -4) so:

since m = 2 and b = -4, we can conclude that the equation would be

Answer:
corresponding sides are congruent, as well as alt. int and alt. exterior angles.
Step-by-step explanation:
Answer:
b=50
c=28
a=16
Step-by-step explanation:
Answer:
slople = -1
Step-by-step explanation:
(x₁ , y₁) = (-3, 4) & (x₂ , y₂) = (2 , -1)
![slope =\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\\\=\frac{-1-4}{2-[-3]}\\\\\\=\frac{-1-4}{2+3}\\\\\\=\frac{-5}{5}\\\\= -1](https://tex.z-dn.net/?f=slope%20%20%3D%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D%5C%5C%5C%5C%5C%5C%3D%5Cfrac%7B-1-4%7D%7B2-%5B-3%5D%7D%5C%5C%5C%5C%5C%5C%3D%5Cfrac%7B-1-4%7D%7B2%2B3%7D%5C%5C%5C%5C%5C%5C%3D%5Cfrac%7B-5%7D%7B5%7D%5C%5C%5C%5C%3D%20-1)
