Answer:
Both lines are not parallel
Step-by-step explanation:
Given as :
Two lines equation are as :
3y - 5x = 9 And y = - 
x - 12
First line is now written in eq y = mx + c
Or, 3y = 5x + 9
Or, y = x + 
So, Slop of this line ( m 1 ) =
slop of second line ( m 2) is 
∵ The slop of both lines are not equal , so the line are not parallel to each other .
Hence Both lines are not parallel Answer

Answer:
B.405 cm2
Step-by-step explanation:
12 times 15 is 315. The area of the rectangle is 315.
The area of the triangle is 90.
Add them and i got 405.
<span>In a system of linear equations we should first try to eliminate one variable. Like this:2a+2x=18........................(1)a+3x=17........................(2)Multiply equation (2) with 2:2a+6x=34....................(3)Subtract 1) and (3):-4x=-16x=4Substitute in 1) or 2) to get 'a' value:a=5Therefore the solution is x=4 and a=5...................(Answer)</span>
