D. No, because all the numbers are positive.

Does The Table Below Represent A Proportional Relationship? A. Yes, Because All The Ratios Of Y To X

Answers

Answer 1

The table represents a proportional relationship because all the ratios of y to x are equal to 3. (option B)

What is a proportional relationship?

Two variables exhibit a proportional relationship if the constant of proportionality remains constant for all the given values in the table.

The equation that is used to represent a proportional relationship is:

y = kx

Where:

k = constant of proportionality

Value of k when x is 1:

3 = k

Value of k when x is 2:

6 = 2k

k = 6 / 2

k = 3

Value of k when x is 3:

9 = 3k

k = 9 / 3

k = 3

Value of k when x is 4:

12 = 4k

k = 12 / 4

k = 3

Before a renovation, a movie theater had 112 seats. After the renovation, the theater has 168 seats. What is the approximate
percentage increase of the number of seats in the theater? If necessary, round to the nearest tenth of a percent
OA. 33.3%
ОВ.
50%
OC. 56%
OD. 20%

Answers

First off, you want to know the actual numerical increase there has been. That is 168-112, which is 56.

So find 56 in terms of percentage of 112. To do so, simply divide 56/112 to get 0.5. That is 50.0% in terms of percentage.

The answer is B.

What is the solution to the system of linear equations?

Answers

Answer:

C. (0, 2)

Step-by-step explanation:

The solution to the systems of linear equations is the coordinates of the point (x, y) where both lines of the equations intercept each other on the graph given.

Thus, the lines intercept at the point where when x = 0, y = 2.

Therefore, the solution = (0, 2).

find the value c that will make 9x^2 +30x+c a perfect square trinomial

Answers

Answer:

[tex] c = 25[/tex]

Step-by-step explanation:

Given :-

A quadratic equation is given to us.The equation is 9x² + 30x + c .

And we need to find out the value of c for which the given trinomial is a perfect square. On looking at the given expression all the terms are having positive signs before them .So we can rewrite it on the basis of ,

Identity :-

[tex]\implies (a+b)^2=a^2+b^2+2ab[/tex]

Let's try to set the equation on this Identity .

The firsr term is 9x² . We can write it as ,

[tex]\implies 9x^2=(3x)^2[/tex]

Hence the middle term here should contain 3 and 2 as their factors. Let's Break the middle term .

[tex]\implies 30x = 2.3x.5 [/tex]

Therefore in order to make the whole expression as perfect square 5² must be replaced by c . The expression would become ,

[tex]\implies 9x^2+30x + 5^2 \\\\\implies (3x)^2+2.3x.5 +5^2\\\\\implies (3x+5)^2[/tex]

Hence the value of c should be 25 .

C = 25 you just multiply step by step exactly how it shows it on the problem/how u wrote it

The perimeter of rectangle living room is 40 m the living room is 10 m wide what is the length of the living room

Answers

Answer:

Width of the room = 5 meters

Step-by-step explanation:

the rectangular living room is calculated as length * width

The area is given to be equal to 40 sq. meters (area = 40 sq. meters)

Let the width = x meters

Length = X+3 meters

Area = Length * Width

40 = X * (X+3)

40 = X^2 + 3X

We solve this quadratic equation

So x = 5 or x= -8

Width  cannot be negative, so we reject x =-8

So x = 5 is the answer

O f(x) = 2x + 2
O f(x) = -27x + 2
O f(x) = - 2x + 2

Answers

Answer:

All of the them excluding f(x)=-27x+2

The required function is [tex]f(x)=-2x^2+2[/tex]. Hence, option a is correct.

Important information:

The graph of a function passes through the points (0,2), (1,0) and (-1,0).Quadratic function:

The graph has two x-intercepts (1,0) and (-1,0). It means it is a quadratic function and [tex](x-1)[/tex] and [tex](x+1)[/tex] are two factors.

[tex]f(x)=a(x-1)(x+1)[/tex]

[tex]f(x)=a(x^2-1)[/tex]         ...(i)

The graph passes through the point (0,2). Substitute [tex]x=0,f(x)=2[/tex] in the above function.

[tex]2=a(0^2-1)[/tex]

[tex]2=-a[/tex]

[tex]-2=a[/tex]

Substitute [tex]a=-2[/tex] in (i).

[tex]f(x)=-2(x^2-1)[/tex]

[tex]f(x)=-2x^2+2[/tex]

Therefore, the correct option is a.

Answer: 8

Step-by-step explanation:

Arrange the data in ascending order, and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers.

Rearrange 9, 9, 2, 8, 11, 6, 4 in ascending order:

2, 4, 6, 8, 9, 9, 11

The number eight appears to be in the very middle, therefore it is the median.

Which expression is equivalent to log 12 x^ 4 sqrt x^ 3 -2 (x+1)^ 5 ?

Answers

The equivalent expression of log₁₂(x⁴√x³) - 2(x+1)⁵ is 11/2log₁₂(x) - 2(x+1)⁵

How to determine the equivalent expression

From the question, we have the following parameters that can be used in our computation:

log 12 x^ 4 sqrt x^ 3 -2 (x+1)^ 5 ?

Express properly

So, we have the following representation

log₁₂(x⁴√x³) - 2(x+1)⁵

Evaluate the exponent

log₁₂(√x¹¹) - 2(x+1)⁵

Apply the power rule of logarithm

This gives

11/2log₁₂(x) - 2(x+1)⁵

Hence, the equivalent expression is 11/2log₁₂(x) - 2(x+1)⁵

40 ft
16 ft
14 ft
10 ft

Answers

Answer:

Area = 780 ft²

Step-by-step explanation:

Area of the shaded region = area of rectangle A + area of rectangle B

Area of rectangle A = L*W

L = 40 ft

W = 16 ft

Area of rectangle A = 40*16 = 640 ft²

Area of rectangle B = L*W

L = 10 ft

W = 14 ft

Area of rectangle B = 10*14 = 140 ft²

Area of the shaded region = 640 + 140 = 780 ft²
