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:

x=1 or x=−3

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%

the output would be y because it is by itself on the left side of the equation symbol.

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.

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.

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, .......}.

Step-by-step explanation:

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.

Step-by-step explanation:

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

Step-by-step explanation:

average rate of change in steel production over the eight days=-0.15 tons per day

Step-by-step explanation:

The production rate of a steel factory is declining due to old machinery. Over the last eight days production has dropped by 1.2 tons.

Production is dropped by 1.2 tons, so its negative

Average rate of change = Change in production / number of days

Average rate of change = -1.2/ 8= -0.15

so sorry -0.15

Answer:

D. 24 degree

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:

Q1. [tex](-\frac{3}{2},0)[/tex]

Q2. (-16, 0)

Step-by-step explanation:

The midpoint of a line segment is given by the formula:

[tex]\boxed{\text{Midpoint}=(\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )}[/tex]

In the formula, [tex](x_1,y_1)[/tex] is the first endpoint while [tex](x_2,y_2)[/tex] is the second endpoint of the line segment.

__________

Q1. Substitute the given endpoints into the formula:

Midpoint

[tex]=(\frac{-5+2}{2} ,\frac{5-5}{2} )[/tex]

[tex]=(\frac{-3}{2} ,\frac{0}{2} )[/tex]

[tex]= \bf{(-\frac{3}{2} ,0)}[/tex]

__________

Q2. Let the other endpoint be (x, y).

Substitute the given midpoint and one endpoint:

(-6, 4)=[tex](\frac{x+4}{2} ,\frac{y+8}{2} )[/tex]

Comparing the x-coordinate:

[tex]\frac{x+4}{2} =-6[/tex]

Multiply both sides by 2:

x +4= -12

Subtract 4 from both sides:
x= -12 -4

x= -16

Comparing the y-coordinate:

[tex]\frac{y+8}{2} =4[/tex]

Multiply both sides by 2:

y +8= 8

Subtract 8 on both sides:

y= 8 -8

y= 0

The coordinates of the other endpoint is thus (-16, 0).

Step-by-step explanation:

your own work, please ...

my own work is

1.

the midpoint between 2 points (x1, y1) and (x2, y2) is

((x1 + x2)/2, (y1 + y2)/2)

so, our midpoint is

((-5 + 2)/2, (5 + -5)/2) = (-3/2, 0/2) = (-3/2, 0)

2.

we have

((x1 + 4)/2, (y1 + 8)/2) = (-6, 4)

so,

(x1 + 4)/2 = -6

x1 + 4 = -12

x1 = -16

(y1 + 8)/2 = 4

y1 + 8 = 8

y1 = 0

so, the other endpoint is (-16, 0).
