Answer:
B
Step-by-step explanation:
-2x + y =3
use 5 number and put it in above equation to find y, I will use -2,-1,0,1,2
x y
-2 -1
-1 1
0 3
1 5
2 7
Then draw the graph, find another point in the graph which intersect the slope,
lets say i found (-3,-3)which is on the slope
to prove it, i put (-3,-3) in the equation -2x + y = 3
and i got
3 = 3
Thus it is correct.
162.15 is the answer because you have to multiply 0.15•141 then add 21.15 to the 141 :)
Answer:
Step-by-step explanation:
The formula of a surface area of a sphere:
R - radius
We have
Substitute and solve for R:
<em>divide both sides by π</em>
<em>divide both sides by 4</em>
The formula of a volume of a sphere:
Substitute:
