I've been stuck on this for a while. a line that passes through the origin has slope m. show how you can use this information, an arbitrary point (x, y) other than the origin, and the slope formula to derive and equation of the line. then rewrite that equation by solving it for y.

i found two solutions,   n = 2 • ± √3 = ± 3.4641

step-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!
