Answer:

4 y = -4 x + 8    or y = -x + 2

y - x = -2           or y = x - 2

using the standard form for a line   y = m x + b

We see that in one equation m = -1 and in the other m' = +1

this is the condition for perpendicular lines

Step-by-step explanation:

The number of dollars for one peso is 20 dollars.

Exchange rate is the rate at which one currency is exchanged for another currency.

In order to determine how many pesos can be exchanged for a dollar, the value of pesos would be divided by the amount of dollars exchanged.

Exchange rate = 5000 / 250 = 20 dollars

This means that 1 peso would be exchanged for 20 dollars.

Answer:

9.2

Step-by-step explanation:

We can use the Pythagorean Theorem, a^2 + b^2 = c^2 to solve this. Since a and b are the lengths of the two sides and c is the length of the hypotenuse, we modify the original formula to c = [tex]\sqrt{a^{2} +b^{2} }[/tex] to find the length of the diagonal. We would get c = [tex]\sqrt{7^{2} +6^{2} }[/tex] = 9.2.

Answer:

y = c+r-7t

Step-by-step explanation:

7t- y+7t=c+r -7t

y = c+r-7t

Answer:

Divide both sides by -10

-10n+2=40

subtract 2 from both sides so

40-2=38

The number of permutations of the 26 letters of the English alphabet that do not contain any of the strings fish, rat, or bird is 402619359782336797900800000

Let

[tex]\mathcal{E}=\{\text{All lowercase letters of the English Alphabet}\}\\\\B=\overline{\{b,i,r,d\}} \cup \{bird\}\\\\F=\overline{\{f,i,s,h\}} \cup \{fish\}\\\\R=\overline{\{r,a,t\}} \cup \{rat\}\\\\FR=\overline{\{f,i,s,h,r,a,t\}} \cup \{fish,rat\}[/tex]

Then

[tex]Perm(\mathcal{E})=\{\text{All orderings of all the elements of } \mathcal{E}\}\\\\Perm(B)=\{\text{All orderings of all the elements of } \mathcal{E} \text{ containing bird}\}\\\\Perm(F)=\{\text{All orderings of all the elements of } \mathcal{E} \text{ containing fish}\}\\\\Perm(R)=\{\text{All orderings of all the elements of } \mathcal{E} \text{ containing rat}\}\\\\Perm(FR)=\{\text{All orderings of all the elements of } \mathcal{E} \text{ containing both fish and rat}\}\\[/tex]

Note that since

[tex]F \cap R=\varnothing[/tex], [tex]Perm(F)\cap Perm(R)\ne \varnothing[/tex]

But since

[tex]B \cap R \ne \varnothing[/tex], [tex]Perm(B)\cap Perm(R)= \varnothing[/tex]

and

[tex]B \cap F \ne \varnothing[/tex] , [tex]Perm(B)\cap Perm(F)= \varnothing[/tex]

Since

[tex]|\mathcal{E} |=26 \text{, then, } |Perm(\mathcal{E})|=26! \\\\|B|=26-4+1=23 \text{, then, } |Perm(B)|=23!\\\\|F|=26-4+1=23 \text{, then, } |Perm(F)|=23!\\\\|R|=26-3+1=24 \text{, then, } |Perm(R)|=24!\\\\|FR|=26-7+2=21 \text{, then, } |Perm(FR)|=21!\\[/tex]

where [tex]|Perm(X)|=\text{number of possible permutations of the elements of X taking all at once}[/tex]

and

[tex]|Perm(F) \cup Perm(R)| = |Perm(F)| + |Perm(R)| - |Perm(FR)|\\= 23!+24!- 21! \text{ possibilities}[/tex]

What we are looking for is the number of permutations of the 26 letters of the alphabet that do  not contain the strings fish, rat or bird, or

C. It is a decimal, it is true of Gemma’s divisor.

The correct answer is: C. It is a decimal.

When Gemma moves the decimal point directly up to the quotient, she is essentially performing long division by powers of 10.

This is because when you divide a number by a power of 10, you are essentially shifting its decimal point to the left by the number of positions determined by the power of 10.

For example, if she is dividing by 100 [tex](10^2)[/tex], she is moving the decimal point two places to the left.

If she is dividing by 1000 [tex](10^3)[/tex], she is moving the decimal point three places to the left, and so on.

Moving the decimal point up to the quotient means that the divisor is a decimal number, and its value determines how many decimal places Gemma needs to move the decimal point in the dividend to get the quotient.

So, the correct answer is C. It is a decimal.

Answer:

Step-by-step explanation:

The equation would be y=12000(2)ˣ.

This equation is of the form y=a*bˣ, where a is the initial population and b is the rate that it increases by.  In this problem, a = 12000 and b=2, since it doubles each time.
