John had $5.00. His mom gave him $5.00 for washing dishes. John went to the store and bought a CD for $6.00. How much money does John have left? Nancy wants to sell 54 CD's to her 6 friends for $5.00 each. How much will Nancy receive from selling her CD's? If each friend buys the same amount of CD's, how many will each friend buy?

$4

Step-by-step explanation:

$5.00+$5.00=$10.00 (when his mom gave him money)

$10.00-$6.00= $4.00 (when he bought the CD)

John has $4.00 left.

Have a great day! :)

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough
