Mathematics
1 answer:
malfutka [58]4 years ago
7 0

Answer:

Step-by-step explanation:

To solve this problem, we need to multiple x and -2 by x^{2} + 2x + 4 and add the results together:

x(x^{2} + 2x + 4)

x^{3} + 2x^{2} + 4x

-2(x^{2} + 2x + 4)

-2x^{2} - 4x - 8

Adding the two together give the following:

(x^{3} + 2x^{2} + 4x) + (-2x^{2} - 4x - 8)

x^{3} - 8

What is the probability of rolling a “4” on a fair 6-sided die and flipping a heads on a fair coin?
Sauron [17]

Answer:

Die: 16. 2/3%

Coin: 50%

Step-by-step explanation:

Well rolling a 4 on a 6 sided die is 1/6.

To make that a percent we first make it a decimal.

1 ÷ 6 = .16666 repeating

To make this a percent we move the decimal place 2 times to the right.

16.2/3%

The chance of flipping a heads on a fair sided coin is 50% because there are two sides with a 50/50 chance of being either.

<em>Thus,</em>

<em>for rolling a 4 on a 6 sided die there is a 16.2/3% chance and a 50% for flipping a heads on a 2 sided coin.</em>

<em />

<em>Hope this helps :)</em>

Can someone pls help
Dominik [7]

Point-slope form:   y - y₁ = m(x - x₁)

m is the slope, (x₁ , y₁) is your point

So your point-slope equation is:

m = -4          (x₁ , y₁) = (4 , -9)

y - y₁ = m(x - x₁)

y + 9 = -4(x - 4)
