Answer:
the volume of a sphere is
Answer:
B) x=8
Step-by-step explanation:
To solve, we must find x like so:
We know that angle AOC = 130, so adding AOB and BOC will equal 130, then we solve for x.
Answer:

Step-by-step explanation:
Answer:
Slope is 5
Step-by-step explanation:
(1, 2) and (3, 12)
m= (y2-y1)/(x2-x1)
m= (12-2)/(3-1)
m= 10/2
m= 5
Answer:
x=2 and y=-1. The steps--
Step-by-step explanation:
<em>FIRST STEP: </em>SUBSTITUTE -4y with the definition in y=2x-5. This makes the first equation -3x-4(2x-5)=-2
<em>SECOND STEP: </em>DISTRIBUTE -4 throughout the parenthesis, making the equation -3x-8x+20=-2.
<em>LAST STEP: </em>SOLVE by combining like terms, -3x-8x, to make -11x, and subtracting 20 from each side, to make -11x=-22. Then divide both sides by -11, making x=2. From there, you solve that y=2(2)-5, solving that y=4-5, y=-1.
Therefore, x=2 and y=-1
