172.2 it correct because u have use you brain and u will get the answer u have to try first and put your mind to it when u do that then u will be able to do anything
keeping in mind that 21 months is more than a year, since there are 12 months in a year, then 21 months is really 21/12 years.


so, clearly, you can see who's greater.
Answer:
see explanation
Step-by-step explanation:
Parallel lines have equal slopes
The product of the slopes of perpendicular lines = - 1
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
All the equations given are in slope- intercept form
y = 2x + 1 → with m = 2
y =
x - 4 → with m = 
y = x + 1 → with m = 1
y = -
x - 3 → with m = - 
y = 10 + x → y = x + 10 → with m = 1
Thus
y = x + 1 and y = 10 + x are Parallel since both have m = 1
y = 2x + 1 and y = -
x - 3 are Perpendicular since 2 × -
= - 1

Answer: Second graph</h3>
Why? Because we draw a dashed line through x = -1/2 = -0.5 on the horizontal number line (aka x axis). Then we shade to the right of this dashed line. The shaded region represents all points that make the inequality true. For example, the point (0,0) is in the shaded region. It has an x coordinate of x = 0 which is larger than -1/2
Side note: the dashed line says "points on this boundary do not count as solutions". So any point with an x coordinate of -1/2 does not count.
Where did PQ come from? if i know what the whole thing is then i can answer.
