Evaluate the expression when n= -2
5n+30

Answer:

sample answer:   If you make a table of values, you can see that 4 quarters equal 1 dollar and 8 quarters equal 2 dollars. If you graph the data, you will see a straight line. Therefore, this situation represents a linear function with a constant rate of change of 1/4

Step-by-step explanation:

The situation is a representation of the linear function.

Given that,

One dollar is divided into four quarters.

The total number of dollars is a function of the number of quarters.

Based on the information presented above, we can conclude that when the dollar represents y value and the quarter represents x value

As a result, the slope should be 1/4.

y = 1/4x should be the linear function.

Hence, As a result, we can conclude that the situation is a linear function.

What is right angled triangle?

A right-angled triangle is a triangle, which has one of its interior angles equal to 90 degree.

Now,

Given that;

⇒ m∠CBD = 90 degree  ….(i)    

We have to prove triangle ABC is right angled triangle.

We can see that the line extends down and perpendicular to the line segment BC at point B.

We can also see that ∠ABC and ∠CBD are supplementary angle.

Hence, We prove as;

         Statement                                                Reason

1) m∠CBD = 90 degree                                        ( Given )

2) ∠ABC and ∠CBD are supplementary.  ( Because ABD is a line and  

                                                                ∠ABC and ∠CBD are linear

                                                                pair)                                                

3). ∠ABC+∠CBD = 180 degree                ( Definition of supplementary)

4) ∠ABC+ 90 = 180 degree                      (  m∠CBD = 90 degree )

5) ∠ABC + 90 - 90 = 180° - 90°            ( subtraction property of equality)

∠ABC = 180° – 90°    (from (i))

∠ABC = 90 degree

6) ∠ABC is a right angle.                     ( Definition of right angle)

7) Δ ABC is a right triangle.                  ( Definition of right triangle)

Therefore, according to definition of right angled triangle,

The triangle ABC is a right angled triangle.

Answer:

$5.76 should be the answer as 14.4 divided by 2.50 gets the answer.

Step-by-step explanation:

The value of the expression when simplified is equal to √5. The correct option is D.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The given radical expression can be simplified as shown below,

5√20 - 3√45

Write the under root values in the factored form,

= 5√(4×5) - 3√(9×5)

Simply the function that can be simplified,

= 5(√4 × √5) - 3(√9 × √5)

= 5(2√5) - 3(3√5)

= 10√5 - 9√5

Take √5 as the common term from the two of the given terms,

= (10 - 9) √5

= 1 √5

= √5

Hence, the value of the expression when simplified is equal to √5.

Answer:

the two numbers are 31 and 32.

Step-by-step explanation:

x+(x+1)=63

2x+1=63

2x=62

x=31

The answers are 31 and 32

The sum of two consecutive numbers is 63. Consecutive numbers are numbers that are in a row (e.g. 1, 2, and 3 are consecutive integers). This means we can represent the two consecutive numbers with x and x+1. Plugging the numbers back into the equation, you get

x + x+1 = 63

Simpifying, you get

2x+1 = 63

Now, you just need to isolate x. To do this, you should subtract 1 from both sides, making the equation.

2x=62

Lastly, you need to divide both sides by 2, making making the equation

x=31

The two integers are x and x+1, and when you plug 31 into that, the numbers are 31 and 32.

It would take him 8 hours

Since every 50 miles takes 1 hour

━━━━━━━☆☆━━━━━━━

▹ Answer

8 Hours

▹ Step-by-Step Explanation

First, find the unit rate:

100 miles ÷ 2 hours = 50 mph

Now, we need to find the time it takes to drive 400 miles so we will divide:

400 miles ÷ 50 mph = 8 hours

If you are looking for total hours, you would add:

2 hours + 8 hours = 10 hours

If you are looking for how long it'll take to drive the 400 miles, it would just remain 8.

Answer:

[tex]\boxed {d = 13}[/tex]

Step-by-step explanation:

Use the Distance Formula to help you find the distance between the two following points:

[tex]d = \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}}[/tex]

(where [tex](x_{1}, y_{1})[/tex] represents the first point and [tex](x_{2}, y_{2})[/tex] represents the second point)

-Apply the two following onto the formula:

[tex](x_{1}, y_{1}) = (8, -7)[/tex]

[tex](x_{2}, y_{2}) = (-4, -2)[/tex]

[tex]d = \sqrt{(-4 - 8)^{2} + (-2 + 7)^{2}}[/tex]

-Solve for the distance:

[tex]d = \sqrt{(-4 - 8)^{2} + (-2 + 7)^{2}}[/tex]

[tex]d = \sqrt{(-12)^{2} + 5^{2}}[/tex]

[tex]d = \sqrt{144 + 25}[/tex]

[tex]d = \sqrt{169}[/tex]

[tex]\boxed {d = 13}[/tex]

Therefore, the distance is [tex]13[/tex].

Step-by-step explanation:

The end behavior of the graph f(x) using limits are

[tex]\lim_{x \to -\infty} f(x) = -\infty[/tex]

and

[tex]\lim_{x \to \infty} f(x) = -\infty[/tex]

Option B is the correct answer.

We have,

From the graph,

As the x-value increases, the function y-values goes to -∞.

As the x-value decreases, the function y-values goes to -∞.

Now,

f(x) is the y-value.

The end behavior of the graph f(x) using limits can be represented as,

[tex]\lim_{x \to -\infty} f(x) = -\infty[/tex]

and

[tex]\lim_{x \to \infty} f(x) = -\infty[/tex]

Thus,

The end behavior of the graph f(x) using limits are

[tex]\lim_{x \to -\infty} f(x) = -\infty[/tex]

Answer:

Step-by-step explanation:

Given the frequency vibrations for a certain guitar string modeled by the equation

F = 200√T where:

T is amount of tantrums in pounds

If the frequency of the vibrations is 600 vibrations per second, the amount of pounds in tantrums will be gotten by substituting F = 600 into the equation and calculating T as shown:

600 = 200√T

Divide both sides by 200

600/200 = 200√T /200

3 = √T

Square both sides

3² = (√T)²

9 = T

T = 9

Hence 9 pounds of tantrum was used to plug the string
