Answer:
option E is the only right answer.
Step-by-step explanation:
parallel means that the lines do not intersect.
Answer:
x = 1
y = -2
Step-by-step explanation:
5x - 2y = 9 -----------(I)
2x + 7y = -12 --------------(II)
Multiply (I) by 7 35x - 14y = 63
Multiply (II) by 2 <u>4x + 14y = - 24</u><u> </u> {Now add and thus y will be eliminated}
39x = 39
x = 39/39
x = 1
Plugin x = 1 in equation(I)
5*1 - 2y = 9
5 -2y = 9
-2y = 9 -5
-2y = 4
y = 4/-2
y = -2

15:12 is the equivalent ratio of 5:4
An equation typically has a slope. Since there is no equation given, I am assuming that 1/7 is the slope:)
1/7 simplified into decimal form is is 0.1428!
