Answer:

Parallel

Step-by-step explanation:

Parallel lines:

The parallel lines have same slope.

y = 2x + 3

Compare with slope y-intercept form of the line: y = mx +b

m is slope and b is the y-intercept.

slope of this line = 2

y = 2x

Slope = 2

These lines have same slope. So, they are parallel.

Answer:

x=-1

Step-by-step explanation:

4x+7=2x+5

subtract 2x on both sides

4x-2x+7=5

4x-2x=2x

2x+7=5

subtract 7 on both sides

2x=-2

divide both sides by 2

x=-1

Answer:

$w = \frac{5}{8}, v = \frac{21}{2}$

Step-by-step explanation:

With given information, we have $\frac{TR}{TQ} = \frac{TS}{TP}$ , so $\frac{5}{13} = \frac{3w}{3w+3}$ , which gives us $w=\frac{5}{8}$ . Meanwhile, we have $\frac{TR}{TQ}=\frac{RS}{QP}$ , so $\frac{5}{13}=\frac{10}{2v+5}$ , which gives us $v = \frac{21}{2}$ .
