So 4•185.95= 743.8
And 10•148.56= 1485.6
Now 1485.6•743.8= 2229.4
Answer is D.$2229.40
X^4-81 =
(x^2-9)(x^2+9) =
(x+3)(x-3)(x^2+9)
There are two real roots (at x=3,-3).
Answer:
All you have to do is insert the first value where the x is, and the second value where the y is.
y = 3x + 5
11 = 3(2) + 5
11 = 6 + 5
11 = 11
So, this is right.
Now, let's check (3,13)
y = 3x + 5
13 = 3(3) + 5
13 = 9 + 5
13 = 14
This is NOT true. So, your answer is: Only (2,11)
Hope this helps!
Answer: Slope is the measure of the steepness of a line. It can be calculated with the equation rise/run or change in y/change in x.

Step-by-step explanation:
The equation of a circle with center (a,b) and radius r, is
From the question, the center of the circle is located at (-6,2) and the radius is
We substitute the center and radius to get:
Simplify to obtain:
