Use the graph to determine which statement describes f(x).

Answers

Answer:

The statements are not provided, so let's do a complete description of f(x)

In the graph, we can see two asymptotes at x = 1.

This means that the denominator is equal to 0 when x = 1, then we can write:

f(x) = A/(x - 1)

Where we can start thinking that A is a constant.

Now we also can see that when x = 2, f(2) is equal to 1, or:

f(2) = 1.

Then:

f(2) = 1   = A/(2 - 1) = A/1

Then we have  A = 1.

Then our function is:

f(x) = 1/(x - 1)

Dino has $1,000 in a savings account that was started for him when he was born. He has a part-time job where he earns $60 each week, and he puts $20 of that into his account each week. An equation could be used to model the amount in his account, y, after x weeks.

Which statements are true about a graph of the equation that will show his account balance during a year? Check all that apply.


A. The x-axis should be labeled from 0 to 12 months since you want to see the change over a year.
B. The x-axis should be labeled from 0 to 52 weekss since you want to see the change over a year.
C. The y-axis should be labeled from $0 to $1,000 since the money in the account will not go above $1,000.
D. The y-axis should be labeled from $0 to $1,300 since the money in the account will not go above $1,300.
E. The y-axis should be labeled from $750 to $1,000 since that is the approximate range of y-values for the year.

URGENT!!!!!! Find the value of q in the following system so that the solution to the system is——

Answers

Answer:  Q = 8

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

Explanation:

The left hand side of the first equation is x-3y

The left hand side of the second equation is 2x-6y = 2(x-3y). Note how it's simply double of the first expression x-3y

If we multiply both sides of the first equation by 2, we get

x-3y = 4

2(x-3y) = 2*4

2x-6y = 8

Meaning that 2x-6y = 8 is equivalent to x-3y = 4. Both produce the same line leading to infinitely many solutions. Each solution will lay along the line x-3y = 4.

We can say each solution is in the set {(x,y): x-3y = 4}

Which is the same as saying each solution is of the form (3y+4,y)

v=vo+at;find a if v = 20, vo = 30, t =5.​

Answers

Answer:

-2 = a

Step-by-step explanation:

v = vo + at

20 = 30 + a5

now get the numbers and the variable on different sides

30 + a5 - 30 = a5

20 - 30 = -10

-10 = a5

now im going to divide each side by 5

a5 / 5 = a

-10 / 5 = -2

-2 = a

Step-by-step explanation:

[tex]V = V _{0} + at \\ 20 = 30 + a \times 5 \\ 5a = 20 - 30 \\ 5a = - 10 \\ \\ a = - \frac{10}{5} \\ \\ a = - 2[/tex]

Look at the middle 7 in the decimal 0.777. How is its value related to the value of the 7 to its left? To the value of the 7 to its right?

Answers

Answer:

Value of middle 7 = [tex]\frac{1}{10}[/tex](value of 7 to the left of the middle 7)

Value of middle 7 = [tex]10[/tex](value of 7 to the right of the middle 7)

Step-by-step explanation:

7 in the middle of number [tex]0.777[/tex] is equal to [tex]\frac{7}{100}[/tex]

7 to the left of the middle 7 is equal to [tex]\frac{7}{10}[/tex]

So,

[tex]\frac{7}{100}=(\frac{1}{10}) \frac{7}{10}[/tex]

That is value of middle 7 = [tex]\frac{1}{10}[/tex](value of 7 to the left of the middle 7)

Also,

7 to the right of the middle 7 is equal to [tex]\frac{7}{1000}[/tex]

So,

[tex]\frac{7}{100}=(10) \frac{7}{1000}[/tex]

That is value of middle 7 = [tex]10[/tex](value of 7 to the right of the middle 7)

Answers

Answer:

Step-by-step explanation:

'll just help with proving whether she is correct.

First of all, a fraction divided by a fraction can be made into multiplication since the division of two fractions is kinda difficult

so remember keep, change, flip

keep the first fractions, change the division symbol into multiplication, then flip the fraction i.e. 1/2 becomes 2/1

so 5/2 divided by 1/4 becomes  

5/2 * 4/1

which then solved becomes

20/2 which is simplified to 10

The recommended storage temperature for a certain type of squash is 10°C to 13°C. Which inequality
represents the possible storage temperatures F (in degrees Fahrenheit) of the squash.

Answers

Answer:

The simultaneous inequation representing the recomended storage temperature is:

[tex]50\,^{\circ}F \leq T \leq 55.4\,^{\circ}F[/tex]

Step-by-step explanation:

In this case, the statement must be represented mathematically by a simultaneous inequation, in which temperature must be equal to or greater than 10 ºC, expressed in Fahreheit degrees, and equal or less than 13 ºC, expressed in Fahrenheit degrees.

Bounds can be converted into Fahrenheit degrees from Celsius degrees:

[tex]T_{F} = \frac{9}{5} \cdot T_{C}+32\,^{\circ}F[/tex] (Eq. 1)

Where:

[tex]T_{C}[/tex] - Temperature, measured in Celsius degrees.

[tex]T_{F}[/tex] - Temperature, measured in Fahrenheit degrees.

Lower bound ([tex]T_{C} = 10\,^{\circ}C[/tex])

[tex]T_{F} = \frac{9}{5}\cdot (10\,^{\circ}C) + 32\,^{\circ}F[/tex]

[tex]T_{F} = 50\,^{\circ}F[/tex]

Upper bound ([tex]T_{C} = 13\,^{\circ}C[/tex])

[tex]T_{F} = \frac{9}{5}\cdot (13\,^{\circ}C) + 32\,^{\circ}F[/tex]

[tex]T_{F} = 55.4\,^{\circ}F[/tex]

The simultaneous inequation representing the recomended storage temperature is:

[tex]50\,^{\circ}F \leq T \leq 55.4\,^{\circ}F[/tex]

Answers

Answer:

C. A loan finances the total purchase price of the car while a lease finances only the depreciated value and related fees

Step-by-step explanation:

He legit said it. (Just writing this for those who are blind)

One difference between obtaining a car with a lease or a loan is that: a loan finances the total purchase price of the car while a lease finances only the depreciated value and related fees.

What is the difference between a Loan and a Lease?

A loan is suitable for a property that you wish to possess at the maturity date, i.e. anything with long-term worth.

On the other hand, a lease is ideal for items that deteriorate gradually and will not retain their worth beyond the period.

The most significant contrast between a lease and a loan is the manner in which the finance costs are paid.

The interest on a loan is amortized throughout the period. i.e. your consumer pays more interest at the start and more principal in the end.

Although leasing is not free, the financing charges are predetermined all through the period and are not deducted from the borrowed amount.

From the information given:

One difference between obtaining a car with a lease or a loan is that: a loan finances the total purchase price of the car while a lease finances only the depreciated value and related fees.
