The equations of three lines are given below. Line 1: y=-5/2x+8
Line 2: 4x-10y=−8
Line 3: 2y=−5x+5
For each pair of lines, determine whether they are parallel, perpendicular, or neither.
Line 1 and 2:
Line 1 and 3:
Line 2 and 3:

what are ur choices?

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!

im guessing (23,14). hope this : )
