Answer: 78.5 units^2
Step-by-step explanation:
The area of the circle is equal to pi*radius^2.
The diameter is double the radius, which means the radius is 10/2 = 5.
Therefore, the area is pi*5^2 = 25pi.
We use 3.14 for pi and we get 25*3.14 = 78.5 units^2
4|x - 1| - 7 = -3 |add 7 to both sides
4|x - 1| = 4 |divide both sides by 4
|x - 1| = 1 ⇔ x - 1 = 1 or x - 1 = -1 |add 1 to both sides
x = 2 or x = 0
Answer: B.
Answer: 8
Step-by-step explanation:
let x = the number
(x + 2)*10 = 8x + 36
10x + 20 = 8x + 36
2x = 16
x = 8
Below are the choices:
<span>-1/2
0
-1
non
</span>
The exclusions are placed on the variable x for the fraction 4x^2-1/4x+2 is -1/2. Below is the solution,
<span>4x+2 = 0 so 4x=-2 so x=-2/4 wich is -1/2</span>
You can say that the slope is negative. A line on a graph that goes from the upper left corner to the bottom right is a negative slope.
