Step-by-step explanation:

3+x=x²+3x

Simply the equations.

= x+3=x²+3x

Subtract x²+3x from both sides.

x+3−(x²+3x)=x2+3x−(x²+3x)

−x2−2x+3=0

Factor left side of equation.

(−x+1)(x+3)=0

−x+1=0 or x+3=0

Answer:

ticket for movie A = 35
ticket for movie B = 12

Step-by-step explanation:

Let A= is ticket  for movie A
Let A= is ticket  for movie B

We have A + B  = 47 (1)
4A + 5B = 200  (2)

From (1) multiply 5 in both side 5A + 5B = 47(5)= 235
                                                     4A + 5B =           200

So A = 35
   B= 47-35 = 12

Answer:

(2, -6, 1)

Step-by-step explanation:

Multiplying the first equation by 2 yields 4x+2y-2z = -6.

Adding this to the second equation, we get 9x=18, and thus x=2.

From the third equation, we know z=1.

From the first equation, it follows that y = -6.

This question is incomplete, the complete question is;

In order to determine an interval for the mean of a population with unknown standard deviation, a sample of 58 items is selected. The mean of the sample is determined to be 36. The associated number of degrees of freedom for reading the t value is :

a. 35.

b. 57.

c. 36.

d. 58.

Answer: Option b. 57 is the correct answer.

Step-by-step explanation:

Given that;

sample size n = 58

sample mean x" = 36

degrees of freedom for reading the t value is = ?

we know that;

Degree of freedom df = n - 1

where n is the sample size

so we substitute

Degree of freedom df = 58 - 1

Degree of freedom df = 57

Therefore Option b. 57 is the correct answer.

Answer:

30/75  2/5

Step-by-step explanation:

there are 30 shaded squares, and a total of 75 squares. Therefore the fraction is 30/75.   This can be simplified to 2/5 if both sides are divided by fifteen.

To make a percentage, simply divide 2 by 5 which equals 0.4 = 40%

Answer:

Step-by-step explanation:

Sides of the triangle are

a = 330 ft

b = 180 ft

c = 420 ft

From cosine rule we have

[tex]\angle A=\cos^{-1}(\dfrac{b^2+c^2-a^2}{2bc})\\ =\cos^{-1}(\dfrac{180^2+420^2-330^2}{2\times180\times 420})\\ =48.65^{\circ}[/tex]

[tex]\angle B=\cos^{-1}(\dfrac{a^2+c^2-b^2}{2ac})\\ =\cos^{-1}(\dfrac{330^2+420^2-180^2}{2\times 330\times 420})\\ =24.17^{\circ}[/tex]

[tex]\angle C=\cos^{-1}(\dfrac{a^2+b^2-c^2}{2ab})\\ =\cos^{-1}(\dfrac{330^2+180^2-420^2}{2\times 330\times 180})\\ =107.19^{\circ}[/tex]

The smallest angle in the triangle is [tex]\angle B=24.17^{\circ}[/tex].

Answer:

Step-by-step explanation :The input-output table is able to “depict the relationship between different sectors of the national economy, and the structural connection of production and final demand in a consistent manner” (KSH, 2005, p. 5). A basic requirement of the table is symmetry, which means that sectoral output and use have to be equal.

The coordinates of Z will be  Z(8,6) and Z(4,2)

The formula for the area of triangle is given as :

               A = 1/2 * b * h

where , b = base

            h = height

We have been a ΔXYZ with coordinates of

    X(-2,2) and Y(8,2)

Also the given area is 20 sq. units

We need to find the coordinates of Z from the given question.

First we will find the length of XY which is

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

     = √(8+2)² + (2-2)²

     = √100

     = 10 units

Let z= (0,6)

distance of YZ = √(0-8)² + (6-2)²

                        = √64+ 16

                        = √80

Area = 1/2 * 10* 4√5 = 20√5 ≠ 20

Let Z = (8,6)

distance of YZ = √(8-8)² + (6-2)²

                        = √16

                        = 4

Area = 1/2 * 10* 4 = 20

let Z = (4,2)

distance of YZ = √(4-8)² + (2-2)²

                        = √16

                        = 4

Area = 1/2 * 10* 4= 20

Let Z = (7,-2)

distance of YZ = √(7-8)² + (-2-2)²

                        = √1 + 16

                        = √17

Area = 1/2 * 10* √17 = 5√17 ≠ 20

Hence the coordinates of Z will be Z(8,6) and Z(4,2) as putting these value we get area equal to 20 square units.

Answer:

(39,000 + 3t = 216000.)  t = 59000

Step-by-step explanation:

(How to find t) First, subtract 39000 from 216000. Divide that by 3. Your answer is 59000.

The reasonable range of the given function is given by {130, 260, 390, 520, .......}.

A range can be defined as the set of all real numbers that connects with the elements of a domain. This ultimately implies that, a range simply refers to the set of all possible output numerical values, which are shown on the y-axis of a graph.

In order to determine the reasonable range of the given function, we would create an input and output table to model the relationship between the range and domain as follows:

x         130x         y___

1          130(1)       130

2         130(2)      260

3         130(3)      390

4         130(4)      520

Therefore, the reasonable range of the given function is given by {130, 260, 390, 520, .......}.
