Answer:
B or D
Step-by-step explanation:
your x point with be really close to 0 but not quite zero while your y would be 3
Answer:
(-3, -6)
Step-by-step explanation:
y=2x
-3x-15=y
Use Substitution Method
-3x-15=2x
+3x +3x
-15=5x
/5 /5
-3=x
y=2x
y=2(-3)
y=-6
Answer:
4.95 and 2.25
Step-by-step explanation:
x+y=7.2
x-y=2.7
Add equations
x+y + x-y= (2x-y+y)=2x
7.2+2.7=9.9
Therefore 2x=9.9 x=9.9/2=4.95
x=4.95
x+y=7.2
4.95+y=7.2
y=7.2-4.95=2.25
y=2.25
Answer:
V = 4.187r³
Step-by-step explanation:
Volume of a sphere is expressed using the formula;
V = 4/3πr³
r is the radius
Substitute π = 3.14 into the formula
V = 4/3 * 3.14r³
V = 4.187r³
Hence the volume of a sphere in terms of the radius is V = 4.187r³
