The answer would be 4
(Positive 4 btw)
Answer:
y = 0
x = -4
( x, y ) = ( -4 , 0 )
Step-by-step explanation:
y = 5x + 20
y = -2x - 8
Substitute
5x + 20 = -2x - 8
Add 8 on both sides
5x + 20 + 8 = -2x - 8 + 8
5x + 28 = -2x
Subtract 5x on both sides
5x - 5x + 28 = -2x - 5x
28 = -7x
Divide by -7 on both sides
28/-7 = -7x/-7
-4 = x
Now that you have x, you can substitute it in one of the equations that was given to find the value of y.
y = 5x + 20
y = 5(-4) + 20
y = -20 + 20
y = 0
Or....
y = -2x - 8
y = -2(-4) - 8
y = 8 - 8
y = 0
They will both be 0 no matter what
Point form = ( -4, 0 )
Hope this helped
Multiply 8 with pi since the equation for circumference is 2pi(r), or d(pi). The answer is 25.13
Answer:
In order: B, A, CB, AB, CD
Step-by-step explanation:
If you read closely, your answers lie within the question.
B is the center of the base.
A is the vertex of the cone.
CB is the radius of the base.
AB is the height from the vertex to the base.
CD is the diameter of the base.
