If r(x) = 3x - 1 and s(x) = 2x + 1, which expression is equivalent to (r/s)(6)?

zavuch27 [327]

Answer:

17/13

Step-by-step explanation:

r(6) = 3(6) - 1 = 17 and s(6) = 2(6) + 1 = 13.

Then (r/s)(6) = 17/13.

Find the slope of each set of points.

Elza [17]

Answer:

1. (4, 3) and (-3, 4) has Slope = -1/7

2.(-2, 0) and (8, -4) has Slope = -2/5

Step-by-step explanation:

If two such points (a,b) and (c,d) are given, then the slope S is given as:

$S = (\frac{d-b}{c-a} )$

Now here, the given set of points are:

1. (4, 3) and (-3, 4)

Here, the slope S = $(\frac{4-3}{-3-4}) = (\frac{1}{-7}) = -(\frac{1}{7})$

⇒ S = -1/7

1. (-2, 0) and (8, -4)

Here, the slope S = $(\frac{-4-0}{8-(-2)}) = (\frac{-4}{10}) = -(\frac{2}{5})$

⇒ S = -2/5
