Which lines is a parallel to the line y=1/2x+5 and passes through the point (-2,1)?
Archy [21]

Answer:

The answer is: y = 1/2x + 2

Step-by-step explanation:

Given equation: y = 1/2x + 5

Given point: (-2, 1)

The slope of the given line is 1/2. Parallel lines have the same slope.

Use the point slope form and solve for y:

y - y1 = m(x - x1)

y - 1 = 1/2(x - (-2))

y - 1 = 1/2(x + 2)

y - 1 = 1/2x + 1/2 * 2

y - 1 = 1/2x + 1

y = 1/2x + 2

Proof:

f(-2) = 1/2(-2) + 2

= -1 + 2

= 1, giving point (-2, 1)

Hope this helps!! Have an Awesome Day!! :-)

Asphere has a diameter of 10 in. What is the volume of the sphere?
Pavel [41]

Answer:\frac{500}{3}π in^{3}

Step-by-step explanation: diameter=10 in

radius=\frac{diameter}{2}=\frac{10}{2}=5 in

volume=\frac{4}{3}r^{3}

=\frac{4}{3}    X 5^{3}  x π =\frac{500}{3}π in^{3}

Are the ratios3:6 and 6:3 equivalent? Why or why not?
uranmaximum [27]

Answer:

No, they are not equivelent.

Step-by-step explanation:

If we solve both of them :

3:6 = 3/6

3/6 = 1/2

1/2 = 1:2

6:3 = 6/3

6/3 = 2/1 (just 2!)

2/1 = 2:1

So, they aren't the same because they aren't the same fraction and they don't simplify to the same answer :)

Let me know if you need more of an explanation!
