Your answer - 130
Answer:
Step-by-step explanation:
you have to have a quadratic equation, not sure what your question is,
First, we need to get all of the r's on the same side. To do this, we need to subtract "r" from both sides.
0.25r - 0.125 + 0.5r - r = 0.5 + r - r
0.25r - 0.125 +0.5r - r = 0.5
Now, we need to add like terms.
0.25r + 0.5r - r - 0.125 = 0.5
-0.25r - 0.125 = 0.5
Now, we need to get the "r" variable by itself.
-0.25r - 0.125 + 0.125 = 0.5 + 0.125
-0.25r = 0.625
Now, we divide both sides by -0.25
(-0.25r) / (-0.25) = 0.625 / (-0.25)
r = -2.5
Answer:
y-6 = -7x + 21
Step-by-step explanation:
Find the slope
(-8 - 6)/(5-3)
-14/2 = -7
Now find the formula
y-6=-7(x - 3)
y-6 = -7x + 21
Another way to write it is
y= -7x + 27
The answer is 6 as 6 x 6 x 6 = 216
