Answer:

7x^2+5x

Step-by-step explanation:

Given

Polynomial 1: 9x^2+8x

Polynomial 2: 2x^2+3x

We have to find subtraction of both

So,

9x^2+8x - (2x^2+3x)

First of all the brackets will be eliminated by multilying the minus sign

9x^2+8x-2x^2-3x

The terms with same power of variable will be written together

9x^2-2x^2+8x-3x

=7x^2+5x ..

Answer:

"the original amount of the loan"

Step-by-step explanation:

x value would be the time in months and y value would be the loan amount that is left.

The y-intercept is basically the point where x is 0. So, we can say the y-intercept would be when time is 0.

That's basically when the loan started and the y-value represents the full loan amount., which is $22,000.

The correct answer is third option -- "the original amount of the loan".

Answer:

The correct option is C.

Step-by-step explanation:

It is given that a scatter plot is made to model the amount of money left to pay on a car loan.

From the given table we can conclude that the number or months represented by variable x and the amount of money owed is represented by variable y.

At y-intercept the value of x is 0. It means the y-intercept represents the amount of money owed when the number of months is 0.

In other words, the y-intercept of the model represents the original amount of loan.

Therefore the correct option is C.

Answer:

(f - g)(x) = (3x + 1) - (x2 - 6) = 3x + 1 - x2 + 6 = -x2 + 3x + 7

i hope this helps.

For this case we have the following functions:

[tex]f (x) = 3x + 1\\g (x) = x ^ 2-6[/tex]

We must find[tex](f-g) (x).[/tex]

By definition we have to:

[tex](f-g) (x) = f (x) -g (x)[/tex]

So:

[tex](f-g) (x) = 3x + 1- (x ^ 2-6)\\(f-g) (x) = 3x + 1-x ^ 2 + 6\\(f-g) (x) = - x ^ 2 + 3x + 6 + 1\\(f-g) (x) = - x ^ 2 + 3x + 7[/tex]

Answer:

[tex](f-g) (x) = - x ^ 2 + 3x + 7[/tex]

Answer:

C. 3

Step-by-step explanation:

Given expression is:

[tex]({3^{\frac{1}{7}})^7[/tex]

We know that the rules of exponents are used to solve these kind of questions.

When there is exponent on exponent like in this question 1/7 has an exponent of 7 , the exponents are multiplied.

So,

[tex]=3^{(7*\frac{1}{7} )}[/tex]

The 7's will be cancelled out and remaining power will be 1

[tex]=3^1\\=3[/tex]

Hence, option C is correct ..

Answer:

The correct answer is option C

3

Step-by-step explanation:

Points to remember

Identities

(xᵃ)ᵇ = xᵃᵇ

(x¹/ᵃ)ᵇ = xᵃ/ᵇ

To find the correct answer

It is given that, (3¹/⁷)⁷

By using above identities we can write,

(3¹/⁷)⁷ = 3⁽¹/⁷ *⁷⁾

= 3¹

 = 3

Therefore the simplified form of  (3¹/⁷)⁷ = 3

The correct answer is option C

(3¹/⁷)⁷ = 3

Answer:

x=21

Step-by-step explanation:

x-7=14

add  7 to both sides

x=21

The expression x - 7 for x = 14 is equal to 7.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

To evaluate x - 7 for x = 14,

We substitute 14 for x and simplify:

x - 7 = 14 - 7 = 7

Therefore,

The expression x - 7 for x = 14 is equal to 7.

Answer:

The probability of drawing three queens is 1/425

Step-by-step explanation:

* lets talk about the deck cards

- The deck cards has 52 cards

- It has four symbols (heart , diamond , clubs , spades)

- Each symbol has 16 cards (from 1 to 10 and king , queen , princess)

* Lets solve the problem

- We will drawing three cards

- The cards are not replaced

- That means the total of the card will reduce by 1 after each drawing

- The cards will drawing are queens

- The first card drawn will be a queen

∵ The first card drawn is queen

∴ The number of cards for the second drawn is 52 - 1 = 51

∵ There are 4 queens in the deck cards we took one for the first choice

∴ The number of queen for the second choice is 4 - 1 = 3

∴ The probability of second choice is 3/51

- Now there are 2 queens and 50 cards after the second choice

∴ The number of the queen is 3 - 1 = 2

∴ The number of the deck cards is 51 - 1 = 50

∴ The probability of third choice is 2/50

- The probability of the three cards is the product of the two fractions

∴ The probability of drawing three queens = 3/51 × 2/50 = 6/2550

- Simplify the fraction

* The probability of drawing three queens = 1/425

Answer:

The third option, or 9, is the answer.

Step-by-step explanation:

The length of the apothem can be found using the pythagorean theorem. Since the length of each side of the hexagon is 10, the base of the triangle is 5, since 10/2=5. Plugging these two values into the pythagorean equation leaves 25+b^2=100.

B^2 = 75, so the length of the apothem is sqrt(75)

this is approximately 8.66, so the answer is 9.

The length of the apothem is 9 inch.

The apothem of a regular polygon is a line segment from the center to the midpoint of one of its sides.

Using the pythagoras theorem.

As, the length of each side of the hexagon is 10.

so, the base of the triangle is 10/2=5.

Now using two values we get

25+b²=100.

B² = 75

Hence, so the length of the apothem is √75 = 8.66 = 9 (approx)

Answer:

Number of cakes decorated = 1.4 in a minute

Step-by-step explanation:

A baker decorates 42 cupcakes in 30 minutes. If she decorates cupcakes at the constant rate then we have to find the number of cakes the baker can decorate in 1 minute.

We should always use the unitary method to calculate the outcome.

∵ A baker can decorate in 30 minutes = 42 cakes

∴ baker can decorate in 1 minute = [tex]\frac{42}{30}=1.4[/tex] cupcakes.

Therefore, 1.4 cakes per minute will be the answer.

Final answer:

To solve the proportion 0.75:n = 5:8, set the two ratios equal to each other and solve for n.

Explanation:

To solve the proportion 0.75:n = 5:8, we can set the two ratios equal to each other:

0.75/n = 5/8

Next, we can cross-multiply to solve for n:

0.75 * 8 = 5 * n

6 = 5n

Lastly, we can divide both sides of the equation by 5 to find the value of n:

n = 6/5

Therefore, n is equal to 1.2.

We can set up and solve a proportion to determine the actual distance between two cities using a scale of distance on a map. The setup would be 1/15 = 9.8/x and by solving this proportion we find the two cities are 147 miles apart.

The topic at hand involves understanding a proportion, an important part of mathematical concepts. More specifically, we are dealing with a proportion that involves distances on a map and the equivalent distances in real life.

For part a) of your question, the proportion can be expressed as '1 inch on the map is to 15 miles in real life as 9.8 inches on the map is to x miles in real life'. In mathematical terms, this can be written as:

1/15 = 9.8/x

For part b) of your question, we can determine the actual distance between Pittsburgh, Pennsylvania and State College, Pennsylvania by solving the proportion for x:

To do this, you can cross multiply (1 * x = 15 * 9.8), getting you x = 147 miles. This means Pittsburgh and State College are 147 miles apart in real life.

Answer:

x = -1.11111111111111(repeating)

Step-by-step explanation:

9x - 1 = -11

Add 1 to each side

9x - 1+1 = -11+1

9x = -10

Divide each side by 9

9x/9 = -10/9

x = -10/9

x = -1.11111111111111(repeating)

For this case we must find the inverse of the following function:

[tex]f (x) = 4x + 7[/tex]

For it:

Replace f (x) with y:

[tex]y = 4x + 7[/tex]

We exchange the variables:

[tex]x = 4y + 7[/tex]

We solve for y:

We subtract 7 on both sides of the equation:

[tex]x-7 = 4y[/tex]

We divide between 4 on both sides of the equation:

[tex]y = \frac {x} {4} - \frac {7} {4}[/tex]

Finally, we change y by[tex]f ^ {- 1} (x)[/tex]:

[tex]f ^ {- 1} (x) = \frac {x} {4} - \frac {7} {4}[/tex]

ANswer:

[tex]f ^ {- 1} (x) = \frac {x} {4} - \frac {7} {4}[/tex]

the inverse function f-1(x) is (x - 7) / 4, which matches option B: f-1(x) = (x / 4) - (7 / 4).

The student asks which of the provided options is the inverse of the function f(x) = 4x + 7. To find the inverse function, we usually swap x and y and then solve for y. The steps to find the inverse are:

Therefore, the inverse function f-1(x) is (x - 7) / 4, which matches option B: f-1(x) = (x / 4) - (7 / 4).
