Consider this expression.
(x + 9)(x - 2) - 9x - 6
What is equivalent?

Answers

Answer 1

Answer:

We can find an expression equivalent to the one given by expanding the expression given,

[tex](x + 9)(x - 2) - 9x - 6\\x^2-2x+9x-18-9x-6\\x^2-2x-24[/tex]

So [tex]x^2-2x-24[/tex] is a possible expression.

Answer 2

The required expression equivalent to (x + 9)(x - 2) - 9x - 6 is  (x + 4)(x - 6).

Given that,
(x + 9)(x - 2) - 9x - 6, an equivalent expression is to be determined.

What are functions?

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

= (x + 9)(x - 2) - 9x - 6
= x² + 9x -2x -18 - 9x - 6
= x² - 2x - 24
= x² -6x + 4x - 24
= x (x - 6) + 4 (x - 6)
= (x + 4)(x - 6)

Thus, the required expression equivalent to (x + 9)(x - 2) - 9x - 6 is  (x + 4)(x - 6).

Tyra buys 14 gallons of gas for $35. How could she figure out how much 1 gallon of gas cost

Answers

Answer:

The cost of 1 gallon is $2.5

Step-by-step explanation:

Given

Cost of 14 gallons = $35

Required

Determine the cost of 1 gallon

From the given parameters, we have:

[tex]14\ gallons = \$35[/tex]

Divide both sides by 14

[tex]\frac{14\ gallons}{14} = \frac{\$35}{14}[/tex]

[tex]1\ gallon = \frac{\$35}{14}[/tex]

[tex]1\ gallon = \$2.5[/tex]

Hence,

Step-by-step explanation:

To solve this, first, take 22 minutes and divide it by 60 minutes, which is the number of minutes in an hour. Then, add two to the value, and multiply it by six square meters per hour, which is the rate that David can paint the wall. From there, you get 14.2 square meters which he painted in 2 hours and 22 minutes. Divide 14.2 square meters by the length of 11 meters to get 1.290 meters. Since they asked you to round to the nearest meter, you get 1 meter.

Answer:

He can buy up to 20 tickets (ie 20 tickets or less)

The equation is 10+3.25x+5 = 80

========================================================

Explanation:

10 = admission cost

3.25 = cost per ticket

x = number of tickets

3.25x = cost from buying x number of tickets

5 = cost of nachos & coke

10+3.25x+5 = total cost of admission, tickets, and food/drink

10+3.25x+5 = 80 since this is the amount he has in his pocket

---------------

Let's solve for x

10+3.25x+5 = 80

3.25x+15 = 80

3.25x = 80-15 .... subtract 15 from both sides

3.25x = 65

x = 65/3.25 ........ divide both sides by 3.25

x = 20

If the triangles are similar, that means their side to side ratios will be the same.

hugo received $100 for his bithday. He then saved $20 per week until he had a total of $460 to buy a printer. Use the equation to show how many weeks it took him to save the money.

Answers

Answer:

18 weeks

Step-by-step explanation:

So, Hugo received $100 for his birthday.

He saved $20 per week. Let x denote the weeks that passed. Therefore:

[tex]y=100+20x[/tex]

This equation represents the total money y Hugo has after x weeks.

The printer cost $460. Thus, set y to $460:

[tex]460=100+20x[/tex]

Solve for x.

Subtract 100 from both sides:

[tex]360=20x[/tex]

Divide both sides by 20:

[tex]x=18[/tex]

Therefore, it took Hugo 18 weeks to save up $460.

What is the domain of this relation?
What is the range of this relation?

Answers

Answer:

Domain ( -4,0, 5) Range ( -7, -3, 2, 6)

Step-by-step explanation:

The domain and range of the given relation {(4, -7), (0, 6), (5,-3), (5, 2)}

is:

Domain = { 4, 0, 5, 5 }

Range = { -7, 6, -3, 2 }

Given,

{(4, -7), (0, 6), (5,-3), (5, 2)}

We need to find what is the domain and range of this relation.

What are the domain and range of a function?

A function has an input and an output.

Example: f(x) = x + 4

Now,

x = 1, 2, 3

f(1) = 1 + 4 = 5

f(2) = 2 + 4 = 6

f(3) = 3 + 4 = 7

Here,
Domain = 1, 2, 3

Range = f(1), f(2), f(3) = 5, 6, 7

We can also write it as { (1,5), (2,6), (3,7)}

Find the relation.

(4, -7)

Here,

domain = 4 and range = -7

(0, 6)

domain = 0 and range = 6

(5,-3)

domain = 5 and range = -3

(5, 2)

domain = 5 and range = 2

Find the domain and range of {(4, -7), (0, 6), (5,-3), (5, 2)}.

Domain = { 4, 0, 5, 5 }

Range = { -7, 6, -3, 2 }

Thus the domain and range of the given relation {(4, -7), (0, 6), (5,-3), (5, 2)}

is:

Domain = { 4, 0, 5, 5 }

Range = { -7, 6, -3, 2 }

Step-by-step explanation:

1. Change f(x) to y

y = 2x – 5

2. Switch x and y.

x = 2y – 5

3. Solve for y by adding 5 to each side and then dividing each

side by 2.

x+5=2y

4. Change y back to f^-1(x)... in other words the inverse

f^-1(x)=(x+5)/2

= 1/2x+5/2

Step-by-step explanation:

y=f-1(x)=1/2(x+5)

explanation: write y equals 2x - 5 and now interchange X and Y it becomes x equals 2y - 5

now solve for y equals F -1 (x) equals 1/2(x + 5)

g(x)= (x + 5) / (2)

is the inverse function of F (x)= 2x - 5
