Point m (3, -2) is the midpoint of ab if the coordinates of a are (-1, 4) then find the coordinates of point b a.( 0,0)
b. (1,1)
c. (7,-8)
d. (2,2)

B(7,-8)

Step-by-step explanation:

Coordinates of m (3,-2)

Coordinates of A (-1,4)

We need to find the coordinates of point B if m is the midpoint of AB. Let the midpoints be (x,y).

Mid-point formula is :

So,

So, the coordinates of B is (7,-8).

is there answer choices?

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
