Y = 0.5x + <span>3.5
this id the equation for a line when </span>Slope = 0.5, y-intercept = 3.5
So first we divide 140 by 7 because our ratio is a total of 7 dollars to get 20
So we multiply both sides of the ratio by 20 to get a ratio of 40:100
We can check our answer and it is right because 100+40=140
Answer:
All triangles have 180 degrees.
Step-by-step explanation:
(4y + 1)(y + 6)
I don't know what you mean by proper location
It shouldn't matter what order the factors are in.
For this case we have the following system of equations:

To solve, we clear "x" from the second equation:

We substitute "x" in the first equation:

We clear the value of the variable "y":

We look for the value of the variable "x":

Thus, the solution of the system is given by:

Answer:

Option D
