slope intercept is basically solve for y y=mx+b m=slope b=yintercept -3x-10y=7 add 3x to both sides -10y=3x+7 divide both sides by -10

The power of a power

The power of a power is related with the multiplication of the exponents. For example:

$(2^4)^5=2^{4x5}=2^{20}$

In this case

$(7^{\frac{1}{2}})^2=7^{\frac{1}{2}\cdot2}$

Then, the exponentes 1/2 and 2 are multiplied.

Since

$\frac{1}{2}\cdot2=1$

Then,

$\begin{gathered} (7^{\frac{1}{2}})^2=7^{\frac{1}{2}\cdot2} \\ =7^1=7 \end{gathered}$

Then, the answer is 7.

Answer- A. 7

The numbers 5, 6, 7, and 8 are randomly arranged to create a four-digit number. What is the probability that the number formed i

myrzilka [38]

Using the arrangements and the probability concept, it is found that there is a 0.75 = 75% probability that the number formed is not divisible by 4.

A probability is the number of desired outcomes divided by the number of total outcomes.

The number of possible arrangements of n elements is given by $A_n = n!$

In this problem, there are 4 elements, hence $n = 4, T = A_4 = 4! = 24$ .

A number is a multiple of 4 if the number composed by it's last 2 digits are multiples of 4.

Hence, the possible options for the last 2 digits are: 56, 68, 76.

For each of them, there are $A_2 = 2! = 2$ options for the first 2 digits, hence, there will be 2 x 3 = 6 multiples of 4.

The other 18 numbers formed are not divisible by 4, hence:

$p = \frac{18}{24} = 0.75$

0.75 = 75% probability that the number formed is not divisible by 4.

you have been given an engine repair job that has a job time of 7 hours how many minutes should you allow for your job?

Soloha48 [4]

Answer:

$Job\ Time = 420\ minutes$

Step-by-step explanation:

Given

$Job\ Time = 7\ hours$

Required

Determine the job time in minutes

To do this, we simply convert the time to minutes.

$1\ hour = 60\ minutes$

$7\ hours = 7 * 60\ minutes$

So, we have:

$Job\ Time = 7 * 60\ minutes$

$Job\ Time = 420\ minutes$

Hence, the job time in minutes is 420 minutes

Which expression can be used to find the difference of the polynomials?

nadya68 [22]

Answer:

D is correct. ( 4m - 5 ) + ( -6m + 7 - 2n )

Step-by-step explanation:

We are given a difference of two polynomial

(4m-5) - (6m-7+2n)

We need to choose correct choice which is equivalent to given expression.

Here we have minus sign between two parentheses.

First we distribute minus sign over (6m-7+2n) using distributive property.

Minus sign will distribute with each term inside (6m-7+2n).

When it will distribute it changes the sign of each term inside the parentheses.

$6m\rightarrow -6m$

$-7\rightarrow +7$

$+2n\rightarrow -2n$

After distribution we get

( 4m - 5 ) + ( -6m + 7 - 2n )

Thus, D is correct option which is similar to given expression.
