r - 4/5r = 1/5r + 1
Subtract 1/5r from each side: r - 4/5r - 1/5r = 1
Combine all the 'r' terms on the left side:
r - 5/5r = 1
r - r = 1
0 = 1
There is no value of 'r' that can make ' 0 = 1 ' a true statement.
So the equation has <em>no solution</em>.

Answer:
The vertex is the point (-1,2)
Step-by-step explanation:
we have
Convert into vertex form
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Complete the square. Remember to balance the equation by adding the same constants to each side.
Rewrite as perfect squares
----> equation in vertex form
The vertex is the point (-1,2)
Answer:
Step-by-step explanation:
32(53) - 30(40) = 1696 - 1200 = 496 <==
D: y=12.5x+15
Using the formula to find the slope given two points:
M= 140-40/10-2= 12.5
we can eliminate the other 3 choices without even finding the Y intercept.
