If the endpoint is (-2,-6) and the midpoint is (8,-1) then what is the other endpoint

(25,-26)

Step-by-step explanation:

difference between the two points in x and y coordinates are

x = 10 - (-5) =15, y = -9 - 8 = -17,

so to get to the other endpoint you need to add another

x = 15 and y = -17 to the midpoint, (10,-9).

10+15 = 25 for x and -9 - 17 is -26 for y.

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!
