The equations of three lines are given below. Line 1: 10x - 4y = 8
Line 2: y = -2/5 - 6
Line 3: 5y = -2x + 3

For each pair of lines, determine whether they are parallel, perpendicular, or neither.

Line 1 and Line 2: Parallel, Perpendicular, or Neither

Line 1 and Line 3: Parallel, Perpendicular, or Neither

Line 2 and Line 3: Parallel, Perpendicular, or Neither

the answer is 24

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!

maybe i can

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
