Answer:

(x-1)^2 + y^2 = 25

Step-by-step explanation:

center C ( ( xA + xB)/2 , (yA+yB)/2 ) = ( 1 , 0)

AB = 10

radius = AB / 2 = 5

equation formula: (x - xC)^2 + (y-yC)^2 = radius^2

Hence:

(x-1)^2 + y^2 = 25

The trail is 3424 miles long . It begins in city A and ends in B. Manfred has hiked 3/8 of that. How many miles has he hiked
Alchen [17]
All we need to do is to find out how much is 3/8 of 3424. We can do it in at least two ways:

1. Divide 3424 by 8 and then multiply the result by 3
2. Just multiply 3424 by 3/8

So:

3424 / 8 = 428
428 * 3 = 1284

or:

3424 * 3/8 =
= 428 * 3/1 =
= 428 * 3 =
= 1284

Answer: Manfred hiked 1284 miles.

If a doesn't equal 0 and the sum of x and 1/a is 0, what does x equal?
Ad libitum [116K]

Answer:

-1/a

Step-by-step explanation:

If a doesn't equal 0 and the sum of x and 1/a is 0, what does x equal?

the sum of x and 1/a is expressed as;

x + 1/a

Equating this to zero

x + 1/a = 0

Find x:

Substract 1/a from bith sides

x + 1/a - 1/a = 0- 1/a

x = -1/a

Hence the value of x is -1/a
