Line k contains the points (4,1) and (2,-2). Graph a
line that is parallel and, in a different color, graph a line
that is perpendicular to Line n but goes through the
point (-2,2).

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!

25/14 or 1.

step-by-step explanation:

the dots mean that it has infinitely more numbers behind it

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1

a ≈ 172.05
