For the plotted points

12

Step-by-step explanation:

Use the Shoelace Theorem.

Area = ( 1/2 ) * { ( -4 * 8 ) + ( -8 * 2 ) + ( -8 * 8 ) - ( -8 * 8 ) - ( -8 * 8 ) - ( -4 *2 ) }

        = ( 1/2 ) * 24

        = 12

according to newton’s cannonball model, what happens if the cannonball's velocity is enough to overpower the pull of earth’s gravitystep-by-step explanation:

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!
