Step-by-step explanation:

Empowerment is easy to know how to resolve one operation of this.

In empowerment there are 3 parts, base, exponent and power.

But in this case there is 1 additional, the sign, that is important to define the power.

In this case the 3 is the base, the exponent is 2, and the sign -

To resolve this operation you need to multiply the base by the times there are on the exponent, if there is a 2 like exponent, you multiply 2 times 3:

3x3 = 9

But because the sign, change the multiplication, if the sign is on base is:

-3x-3 = 9

The 2 operation give the same result because on negative rules, on multiplication, even negative numbers give always positive result and odd negative numbers give always negative result.

Then the power is 9

Answer:

49x-44 is it.

Step-by-step explanation:

Answer: It is not a function.

Step-by-step explanation:

A function is something that "eats" an input and transforms it into an output.

We write them as y = f(x)

Where x is the input, and y is the output.

Now, a function has an important rule, for each input x, the function can only "transform it" (or map it) into only one possible output.

This means that, for example, if we have, for x = x1.

And a single

f(x1) = y1

f(x1) = y2

where y1 and y2 are different values.

Then this is not a function, because it is mapping the value x1 into two different outputs.

In this case, we would have:

f(Z) = A.

So Z is the input, but we know that a ZIP code works for an entire city, and in a given city we have lots of different street addresses, then for a single value of the input, Z, we have a lot of possible values of the output.

This means taht the set (Z, A) can not represent a function.

Answer:

227.5

Step-by-step explanation:

Find the number that is increased by 30% to get to 325.  

100-30 = 70.

In other words, what number is 70% of 325.

325 x .70 = 227.5

The original price of the ring was 227.5.

Check your work, 227.5 = 70% of X

227.5  / .70  = 325

Answer:

The cost before the increase is £250.

Step-by-step explanation:

Given that after 30% increases, the cost of the ring is £325 so we can assume that 130% is £325. Now, we have to form an expression in term of x where x represents the original cost :

[tex] \frac{130}{100} \times x = 325[/tex]

Next, we have to solve it :

[tex]x = 325 \div \frac{130}{100} [/tex]

[tex]x = 325 \times \frac{100}{130} [/tex]

[tex]x = 250[/tex]

yes

The direction and strength of the association between the variables is weak negative correlation. Therefore, option A is the correct answer.

The given coordinates are (0, 8), (12, 0), (2, 5), (10, 1), (9, 3), (5, 2), (6, 2) and (4, 0).

Correlation is a key statistical measure that describes the degree of association between two variables. There are three basic types of correlation: positive correlation: the two variables change in the same direction. negative correlation: the two variables change in opposite directions.

The coordinate points (0, 8), (12, 0), (2, 5), (10, 1), (9, 3), (5, 2), (6, 2) and (4, 0) are plotted in the graph below and it shows weak negative correlation.

The direction and strength of the association between the variables is weak negative correlation. Therefore, option A is the correct answer.

Answer:

Fraction: 8 [tex]\frac{11}{20}[/tex]

Decimal: 8.55

Step-by-step explanation:

8 11/20 is the answer because:

1) Since 8 is the whole number, 8 wouldn't be part of the fraction

2) The numerator is the top number in the fraction, so 11 is at the top since 11 is the numerator

3) The denominator is the bottom number in the fraction, so 20 is at the top since 20 is the denominator

8.55 is the answer because:

1) Since 8 is the whole number, 8 would be in front of the decimal point

2) When you multiply the fractions, you have to multiply until you get a hundred. Therefore, 20*5 = 100 and 11*5 = 55

Answer:

[tex]y = 3(x +21)[/tex]

Step-by-step explanation:

Find the inverse this equation:

[tex]f(x) = (\frac{1}{3}x) - 7[/tex]

-Take the variable [tex]y[/tex] for [tex]f(x)[/tex], because both

[tex]y = (\frac{1}{3}x) - 7[/tex]

-Switch both variable [tex]x[/tex] and [tex]y[/tex] :

[tex]y = (\frac{1}{3}x) - 7[/tex]

[tex]x = (\frac{1}{3}y) - 7[/tex]

-Solve for [tex]y[/tex] :

[tex]x = (\frac{1}{3}y) - 7[/tex]

-Switch sides:

[tex]\frac{1}{3}y - 7 = x[/tex]

-Add both side of the equation by [tex]7[/tex] :

[tex]\frac{1}{3}y - 7 + 7 = x + 7[/tex]

[tex]\frac{1}{3}y = x + 7[/tex]

-Multiply both sides by [tex]3[/tex] :

[tex]\frac{\frac{1}{3}y}{\frac{1}{3} } = \frac{x + 7}{\frac{1}{3} }[/tex]

[tex]y = \frac{x + 7}{\frac{1}{3} }[/tex]

-Divide [tex]x + 7[/tex] by multiplying by [tex]\frac{1}{3}[/tex]

[tex]y = \frac{x + 7}{\frac{1}{3} }[/tex]

[tex]y = 3(x +21)[/tex]

Therefore, the answer is [tex]y = 3(x +21)[/tex].

Answer:

8 groups of 75, 10 groups of 60, 12 groups of 50.

Step-by-step explanation:

600/12=50

600/10=60

600/8=75

The possible groupings are:

50 groups with 12 jellybeans each.

40 groups with 15 jellybeans each.

30 groups with 20 jellybeans each.

24 groups with 25 jellybeans each.

12 groups with 50 jellybeans each.

10 groups with 60 jellybeans each.

8 groups with 75 jellybeans each.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Chloe wants to divide 600 jellybeans into equal groups. She wants each group to have more than 10 jellybeans, but less than 100.

This means,

we need to find three numbers between 10 and 100 that are a factor of  600.

We  can have,

12, 15, 20, 25, 50, 60, 75

We can have,

50 groups with 12 jellybeans each.

40 groups with 15 jellybeans each.

30 groups with 20 jellybeans each.

24 groups with 25 jellybeans each.

12 groups with 50 jellybeans each.

10 groups with 60 jellybeans each.

8 groups with 75 jellybeans each.

These are the possible grouping we can have,

We can choose any three groupings.

Thus,

The possible groupings are:

50 groups with 12 jellybeans each.

40 groups with 15 jellybeans each.

30 groups with 20 jellybeans each.

24 groups with 25 jellybeans each.

If a function has a counterpart with the numerator and denominator switched multiplied by -1, then it is perpendicular. Also, here's image proof.

Answer:

1) x=14

2) n=21/8=2.625

Step-by-step explanation:

1)

So we have the equation:

[tex]\frac{x}{16}-\frac{1}{2}=\frac{3}{8}[/tex]

First, let's remove all the fractions. Multiply both sides by the LCM of 16, 2, and 8, which is 16. So:

[tex]16(\frac{x}{16}-\frac{1}{2})=16(\frac{3}{8})[/tex]

Distribute:

[tex]16(\frac{x}{16})-16(\frac{1}{2})=16(\frac{3}{8})[/tex]

Simplify:

[tex]x-8=6[/tex]

Add 8 to both sides:

[tex]x=14[/tex]

So, the value of x is 14.

2)

We have:

[tex]\frac{3n}{7}-1=\frac{1}{8}[/tex]

Again, let's remove the fractions by multiplying both sides by the LCM of 7 and 8, which is 56. So:

[tex]56(\frac{3n}{7})-56(1)=56(\frac{1}{8})[/tex]

Simplify:

[tex]24n-56=7[/tex]

Add 56 to both sides:

[tex]24n=63[/tex]

Divide both sides by 24:

[tex]n=63/24[/tex]

Reduce:

[tex]n=21/8=2.625[/tex]

And we're done!
