Which statement best describes the graphs of the lines y=-x-3 and y=x+6
A) They are the same line.
B) They are parallel lines.
C) They intersect at exactly one point.
D) They intersect at exactly two points.

Step-by-step explanation:

C they intersect only once  and are also perpendicular lines

x^6

step-by-step explanation:

this is correct because:

x-6=0

0*x=0

so

x^6

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!
