Point c is the midpoint of ab. point a has coordinates (2,4)and point c has coordinates (5,0) what are the coordinates of point b?

The coordinates of point B is (8,-4)

Step-by-step explanation:

Midpoint of a line segment: It is the point on the line segment that divides the segment in two congruent segments.

Since it is given that C is the midpoint of Line segment AB.

Mid-point of a segment of end points and is, C= .

As, given the coordinates of A and C are (2,4) and (5,0)

then,  we have , ;  and

to find the coordinates of .

Simplify:

⇒

to solve for we have,

or

or = -4

so, the values of and

Therefore, the coordinates of point B is (8,-4)

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500

answer: its the third option.
