Identify the asymptotes, domain, and range
f(x)=-1/x+4

Just do number 2 at the least, if you want to do more ill give brainliest

Answers

Answer 1
Domain is -1 and the range is 4.
Answer 2

1.

[tex]f(x)=\dfrac1{x-1}=\dfrac1{x-1}+0[/tex]

x-1 = 0  for  x = 1

so:

Vertical asymptote: x = 1

Domain:  Dom f = R\{1}  {or: Dom f = (-∞, 1)∪(1, ∞)}

Horizontal asymptote:  y = 0

Range:    Ran f=R\{0}  {or: Ran f = (-∞, 0)∪(0, ∞)}

2.

[tex]f(x)=\dfrac{-1}{x}+4=\dfrac{-1}{x-0}+4[/tex]

x-0 = 0  for  x = 0

so:

Vertical asymptote: x = 0

Domain:  Dom f = R\{0}  {or: Dom f = (-∞, 0)∪(0, ∞)}

Horizontal asymptote:  y = 4

Range:    Ran f=R\{4}  {or: Ran f = (-∞, 4)∪(4, ∞)}

3.

[tex]f(x)=\dfrac{1}{x+3}-3[/tex]

x+3 = 0  for  x = -3

so:

Vertical asymptote: x = -3

Domain:  Dom f = R\{-3}  {or: Dom f = (-∞, -3)∪(-3, ∞)}

Horizontal asymptote:  y = -3

Range:    Ran f=R\{-3}  {or: Ran f = (-∞, -3)∪(-3, ∞)}

4.

[tex]f(x)=\dfrac{-1}{x+5}-6[/tex]

x+5 = 0  for  x = -5

so:

Vertical asymptote: x = -5

Domain:  Dom f = R\{-5}  {or: Dom f = (-∞, -5)∪(-5, ∞)}

Horizontal asymptote:  y = -6

Range:    Ran f=R\{-6}  {or: Ran f = (-∞, -6)∪(-6, ∞)}

4.

[tex]f(x)=\dfrac{-1}{x+1}+3[/tex]

x+1 = 0  for  x = -1

so:

Vertical asymptote: x = -1

Domain:  Dom f = R\{-1}  {or: Dom f = (-∞, -1)∪(-1, ∞)}

Horizontal asymptote:  y = -6

Range:    Ran f=R\{3}  {or: Ran f = (-∞, 3)∪(3, ∞)}

5.

[tex]f(x)=\dfrac{1}{x+4}-2[/tex]

x+4 = 0  for  x = -4

so:

Vertical asymptote: x = -4

Domain:  Dom f = R\{-4}  {or: Dom f = (-∞, -4)∪(-4, ∞)}

Horizontal asymptote:  y = -2

Range:    Ran f=R\{-2}  {or: Ran f = (-∞, -2)∪(-2, ∞)}

The scale of a model train is 1 1 inch to 13.5 13.5 feet. One of the cars of the model train is 5 5 inches long. What is the length, in feet, of the actual train car?

Answers

Answer:

74.25feet

Step-by-step explanation:

Given the scale of a model train expressed as;

1in = 13.5feet

We are to express length of 5.5in in feet

5.5in = x

Divide both expressions

1/5.5 = 13.5/x

Cross multiply

1×x = 5.5× 13.5

x = 74.25feet

Hence the actual length of the car in feet is 74.25feet

Parson City Middle School has 1,340 students. About 38% of the students are in the seventh grade. About how many seventh-graders attend Parson City Middle School?

Answers

Answer: About 509 seventh-graders attend Parson City Middle School.

Step-by-step explanation:

Total students in the school = 1,340

About 38% of the students are in the seventh grade.

Number of students in the seventh grade = 38% of (Total students in the school)

= 0.38 x (1340)     [38%= 0.38]

= 509.2 ≈ 509

Hence, About 509 seventh-graders attend Parson City Middle School.

A salesperson at a jeweraly store that earns 7% commission each week last week Jared sold $680 worth of jewelry how much did he make in commission how much did the jewelry store make from his sales

Answers

Given :

A salesperson at a jewelry store that earns 7% commission each week last week Jared sold $680 worth of jewelry.

To Find :

How much did he make in commission.

Solution :

Let, commission he make is C.

So, C is 7% of $680 .

[tex]C = \dfrac{680\times 7}{100}\\\\C = \$ 47.6[/tex]

Therefore, salesperson will make $47.6 commission.

7x + 5 = 3(2x + 3) + x - 4​

Answers

Answer:

Infinite Many Solutions

0 = 0

Step-by-step explanation:

7x + 5 = 3(2x + 3) + x - 4​ (Given)

7x + 5 = 6x + 9 + x - 4 (Distributive Property Of Equality)

7x + 5 = 7x + 5 (Combine Like Terms)

0 = 0 (Subtraction Property Of Equality)

As you see it's the same thing in both sides and if you solve it gives 0 = 0 because it would cancel each other out and since 0 is equal to 0 it's infinite many solutions.

Answer:

The answer is 68 and 52

Step-by-step explanation:

x + y = 120

3(x - y ) = 48

We have 3x + 3y = 360

and 3x - 3y = 48

Adding we have the following:

6x = 408

x = 68

y = 120-48 = 52
