Answer:

$x-6=-2$

Step-by-step explanation:

Let $x$ , be "a number".

6 less, would be $x-6$ . "Is" means equals ( = )

You then can put that together to get your equation.

<em>Hope this helps!!!</em>

Fred flips a coin, spins the spinner, and rolls a standard number cube. Find the probability that the coin will show tails, the

Inessa05 [86]

Answer:

The probability that the coin will show tails, the spinner will land on yellow or green (out of yellow, green, blue), and the cube will show a three is $\frac{4}{3}$

Step-by-step explanation:

Given : Fred flips a coin, spins the spinner, and rolls a standard number cube.

To find : The probability that the coin will show tails, the spinner will land on yellow or green (out of yellow, green, blue), and the cube will show a three ?

Solution :

First we find probability one by one,

1) Flips a coin - Head, Tail

Total number of outcome = 2

Favorable outcome (getting a tail) = 1

Probability that the coin will show tails is $P(T)=\frac{1}{2}$

2) Spins the spinner - yellow, green, blue

Total number of outcome = 3

Favorable outcome (land on yellow or green) = 2

Probability that the spinner will land on yellow or green $P(S)=\frac{2}{3}$

3) Rolls a standard number cube - 1,2,3,4,5,6

Total number of outcome = 6

Favorable outcome (show a three) = 1

Probability that the cube will show a three $P(C)=\frac{1}{6}$

The probability that the coin will show tails, the spinner will land on yellow or green (out of yellow, green, blue), and the cube will show a three is

$P=P(T)+P(S)+P(C)$

$P=\frac{1}{2}+\frac{2}{3}+\frac{1}{6}$

$P=\frac{3+4+1}{6}$

$P=\frac{8}{6}$

$P=\frac{4}{3}$

Therefore, The probability that the coin will show tails, the spinner will land on yellow or green (out of yellow, green, blue), and the cube will show a three is $\frac{4}{3}$

How do you start this

lidiya [134]

You have two equations.
since the second is already isolated, sub in x-4 for every y in equation 1 so that
$x^{2} - 4 [(x-4)^{2}] =16
$
expand, collect like terms, factor to find x, then plug x value back into original equation to find y

HELP MEEE!! Please evaluating a compound. Inequality using a graph

Irina-Kira [14]

Answer:

$\frac{x}{2}$

Step-by-step explanation:

From the graph, we can conclude that,

$x$ is less than 2 and not including as there is a hollow circle at the mark 2.

Also, $x$ is greater than or equal to 7 including 7 as there is a solid circle at the mark 7

So, the compound inequality will be $x$

Now, the option that simplifies to the above inequality is the required answer.

Let us check the first option.

$\frac{x}{2}$

Therefore, option 1 simplifies to the above compound inequality.

So, the correct answer is option 1.

If f(x)=3^2 and g(x)=4x^3+1 , what is the degree of (f*g)(x)?

N76 [4]

I'm assuming you meant to say f(x) = 3x^2. If that assumption is correct, then the degree is found by multiplying the leading terms from both f(x) and g(x). The leading terms are 3x^2 and 4x^3

3x^2*4x^3 = (3*4)*(x^2*x^3) = 12x^(2+3) = 12x^5

The exponent of that result is 5, so the degree of (f*g)(x) is 5

Answer: 5
