Answer:
y = 2x + 1 --> linear
y = -4x + 7 --> non-linear
Not a solution for a linear system.
Step-by-step explanation:
for (a), y = 2x+1, substitute the x and y values. keep in mind, that in a linear pair, (x, y). So, for the first equation you get:
7 = 2x3 + 1. This is correct, because 6 + 1 is 7. Therefore, (a) is linear.
for (b), we have to substitute our values again. You get:
7 = -4x3 + 7, which is
7 = -12+7, which is not true. So, (b) is not linear.
This means that for the linear pair (3, 7), it does not satisfy both equations, which means that it is not a solution for the linear system.

Answer:
Step-by-step explanation:
5) 6:18 = 1:3
6) 10:12 = 5:6
7) 12:28 = 6:14 = 3:7
8) 18:24 = 6:8 = 3:4
9) 16:20 = 8:10 = 4:5
10) 15:9 = 5:3
11) 5:30 = 1:6
12) 14:10 = 7:5
13) 6:16 = 3:8
14) 20:35 = 4:7

Answer:
MRCORRECT has answered the question
Step-by-step explanation:
Option (3) and (4) are correct .
w║n and n⊥m and w║n so w⊥m
Step-by-step explanation:
In the given figure, we have a set of lines which are parallel and perpendicular.
Parallel lines are lines in same plane which when extended do not meet and are always same distance apart from each other.
Perpendicular lines are two non-vertical lines in the same plane intersect at right angles.
From the figure given,
w║n and n⊥m as angle between a and n is right angle that is ∠mxn = 90° (given)
Since, w║n so w⊥m also both w and n shows same property as both are parallel lines.
Thus, option (3) and (4) are correct .
