Answer:

24/49

Step-by-step explanation:

The options to get 2 of different color is picking blue then red or red then blue.

Starting with picking blue then red.

The chance to pull blue first is 3/7. Then since the marble is replaced the chance to pull red next is 4/7.

The chance to get those in that specific order is the product of the two fractions. (3/7) * (4/7) = 12 / 49

The second option of getting red then blue will be the same as above but 4/7 then 3/7 with the same result of 12/49.

To finish, add the two probabilities together 12/49 + 12/49 = 24/49.

F(x) and g(x) were inverse functions, then if f(a) = b, then g(b) = a

f(x) = (5x+1) / x g(x) = x / (5x+1)

f(1) = 6, but g(6) = 6/31 ≠ 1

So, f(x) and g(x) are NOT inverse functions.

What is the equation of a line that passes through the point(3,-8)and has a slope of 0?

hram777 [196]

Answer: y=-8

Step-by-step explanation:

If the slope is zero that means that the line does not go up (or have any rise) and therefore must be a horizontal line. Since it passes through the point (3,-8), the equation has to be y=-8.
