M(5, 7) is the midpoint of mc140-1.jpg. the coordinates of s are (6, 9). what are the coordinates of r? (4, 5) (7, 11) (5.5, 8) (10, 14)

(4,5)

Step-by-step explanation:

Given that M is the midpoint of the Line RS. Where the coordinates of M, R and S are

M(5,7)

R(X,Y)

S(6,9)

Here we have to find the valuer of X and Y

We will use the mid point formula which is given below.

Let put the coordinated of M and S and find coordinates of R

Hence our coordinates are

(4,5)

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
