Determine whether the relationship being represented is Linear, Exponential or Neither : LaTeX: f\left(x\right)=\frac{1}{3}x+2f ( x ) = 1 3 x + 2 Group of answer choices Linear Exponential Neither

Answers

Answer:

Linear

Step-by-step explanation:

Given

[tex]f\left(x\right)=\frac{1}{3}x+2[/tex]

Required

Determine the relationship

From the group of options, Linear answers the question.

This is so because, a linear equation is of the form: [tex]f(x) = ax + b[/tex]

By comparing [tex]f(x) = ax + b[/tex] with [tex]f\left(x\right)=\frac{1}{3}x+2[/tex], we have that:

[tex]a = \frac{1}{3}[/tex]

[tex]b = 2[/tex]

and

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

Hence, the equation is a linear equation

∠A is complementary to ∠B. The measure of ∠A is (8x+12)∘. The measure of ∠B is half the measure of ∠A.

Write an equation that can be used to determine the value of x. Then solve for x.

Answers

8x+12/2 is the answer

The equation that can be used to solve for x is 8x + 12 + 4x + 6 = 90.

The value of x is 6.

What is an expression?

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,

∠A and ∠B are complementary.

This means,

∠A + ∠B = 90

Now,

∠A = 8x + 12

∠B = (8x + 12)/2 = 4x + 6

Now,

8x + 12 + 4x + 6 = 90

12x + 18 = 90

12x = 90 - 18

12x = 72

x = 72/12

x = 6

Thus,

The value of x is 6.

A fruit jucie company includes 1.231 ounce of apple jucie in 6.65- ounces bottel of a mixied fruit jucie. How much of the bottel of mixied fruit jucie is NOT apple jucie? THANK YOU!

Answers

Answer: 81.49% of bottle of mixed fruit juice is NOT apple juice.

Step-by-step explanation:

Quantity of mixed fruit juice  = 6.65 ounces

Quantity of apple juice in it = 1.231 ounce

Quantity of mixed fruit juice is NOT apple juice = (6.65-1.231) ounces

= 5.419 ounces

Fraction of bottle is not apple juice = [tex]\dfrac{5.419}{6.65}\approx0.8149=81.49\%[/tex]

Hence, 81.49% of bottle of mixed fruit juice is NOT apple juice.

a suitcase measures 24 inches long and 18 inches high, what is the diagonal length of the suitcase?

Answers

Answer:

The diagonal is 30 inches

Step-by-step explanation:

Assuming a rectangular suitcase (with right angles), we can use the Pythagorean theorem to solve this

a² + b² = c²

so we plug our two values to find the diagonal (hypotenuse)

24² + 18² = c²

576 + 324 = c²

900 = c²

c = √900

c = 30

The diagonal is 30 inches

Answer:

the diagonal is 30 inches

Step-by-step explanation:

you assume a suitcase is a rectangular shape, and the diagonal length makes 2 right triangles; therefore you can use Pythagorean theorem

[tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex] ; where a = 24, b = 18 and c is the diagonal

[tex]24^{2}[/tex] + [tex]18^{2}[/tex] = [tex]c^{2}[/tex]

[tex]c^{2}[/tex] = 576 + 324

[tex]c^{2}[/tex] = 900

c = 30 inches

Use the distributive property to expand 0.05(50 + 40).

Answers

Answer:

4.5

Step-by-step explanation:

Here's what I found on google about distributive property:

To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

Now for the math-

distribute the numbers-  0.05(50)+0.05(40)

solve-  0.05*50= 2.5

0.05*40= 2

State the independent variable and the dependent variable in the linear relationship. Then find the rate of change for the situation. The cost of dinner is $42 for three people and $98 for seven people

Answers

Answer:

144

Step-by-step explanation:

The independent variable in the linear relationship is the number of people.

The dependent variable in the linear relationship is the cost of the dinner.

What is an expression?

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,

Cost of dinner for 3 people = $42

Cost of dinner for 7 people = $98

The cost of dinner for one person = $14

Now,

The linear function for this relationship.

f(x) = 14x

Where x is the number of people and f(x) is the cost of the dinner.

Now,

The number of people is the independent variable.

The cost of dinner is the dependent variable.

Thus,

Independent variable = Number of people/

Dependent variable = Cost of the dinner.
