Answer:

(A)C,D,A,B

Step-by-step explanation:

f(x) = x^2- 2x\\g(x) = x^3-1

a) f(-2)

f(-2) = (-2)^2- 2(-2)\\=4-(-4)\\=4+4\\=8$ (C)

b) g(-2)

g(-2) = (-2)^3-1\\\=-8-1\\=-9 $(D)

c) f(-1)+g(3)

f(-1) = (-1)^2- 2(-1)=1+2=3\\g(3) = (3)^3-1=27-1=26\\f(-1) + g(3)=3+26\\=29$ (A)

d) f(5) : g(2)

f(5) = (5)^2- 2(5)=25-10=15\\g(2) = (2)^3-1=8-1=7\\f(5) :g(2)=15/7$ (B)

What is the soulution of -(-5-6x) = 4(5x+3)?
Fynjy0 [20]
You have to distribute the parentheses first. Since there is a negative sign in front of the parentheses, it counts as a negative 1. After you distribute you should get: -5+6x=20x+12, but that is not your final answer. After you add like terms: 17x=-17. Divide 17 on both sides: x=-1. X=-1 is your final answer.

What is the probability that the card drawn is a diamond and a jack​
SpyIntel [72]

Answer:

1/26=4/104

Step-by-step explanation:

The probability of pulling a diamond if completely shuffled properly, is a 1/4. Because there are 4 suits. This is only if, there are no jokers.

And the probability of pulling a jack, is a 4/51. Because there are 4 jacks out of the 51 cards, but you already pulled out a diamond card, so you take 1 out.

Multiply them together, and you will get 4/104 = 1/26

There is a 1/26 chance of pulling out a diamond card, then a jack.
