Answer: 40 miles/hr

Step-by-step explanation:

The unit rate is the slope of the line.  The slope is the Rise/Run, so pick any two points and calculate.  I'll pick (2,80) and (4,160).

Rise is (160-80) = 80

Run is (4-2) = 2

Rise/Run, or slope, is 80/2 or 40 (miles/hour)

Answer:

C - 40

Step-by-step explanation:

The unit rate in a graph is how much a unit increases with time. The unit here is Distance (mi) and the time here is Time (h). So to find the unit rate, you divide the y-value with its corresponding x-value (given it is a straight line, which it is in this case).

So for example, let's take the unit 80mi, its corresponding x-value is 2, so 80/2 = 40. Let's do the same for 160mi, its corresponding x-value is 4, so 160/4 = 40 and so on. The value will be the same for all x-y values in the graph.

We bought 3 pairs of socks and 2 handkerchiefs for $ 1.45 and, yesterday, 2 pairs of stocking and 5 handkerchiefs for $ 1.75. De
alexgriva [62]
Equations for the numbers of pairs of socks (s) and handkerchiefs (h) can be written as
  3s +2h = 1.45
  2s +5h = 1.75

These can be solved by any of your favorite means to find
  s = 3.75/11 ≈ 0.341
  h = 2.35/11 ≈ .214

The price of a pair of socks and a handerchief is $0.34 +0.21 = $0.55.

Which of the following methods would be the easiest to use to solve x2 + 5x – 6 = 0?
EastWind [94]
For me personally, the easiest way to do this is by isolating the x² term, and finding the square root of both sides. The hardest way (well actually, the longest way) would be to use the quadratic formula. It just complicates things unnecessarily.
