First, you can factor out the -. You then get
.
It becomes clear that this is a difference of squares. So, you can factor this to be
Plugging in the - into one of the two factors gives you
Therefore, the answer is A.
Answer:
the real answer is 112.3 revolutions.
Step-by-step explanation:
because I took this test and this is the answer not 705.6.
Answer:
(3, 1) and (6, -2)
Step-by-step explanation:
Just look at the interceptions
Answer:
y = -3x + 8
Step-by-step explanation:
The slope of a perpendicular line to the original equation is the opposite reciprocal of the slope of the original equation. This makes the opposite reciprocal -3, so the slope of the perpendicular line is -3.
Now that we have found the slope, we will put it into the formula for slope, y = mx + b. This results in getting y = -3x + b.
We know the values for x and y, (1,5) respectively. Plug these values into y = -3x + b.
5 = -3(1) + b
b = 8
This means that 8 is your y intercept and goes into place for b
Therefore, your resulting equation is y = -3x + 8
The radius of a circle is
always half of the diameter of the circle. In this case, the diameter is
, meaning that when we halve
, we will get our radius. Therefore, the radius of the circle is
. Hope this has helped you understand and have a great day!
