ANSWER:

x = 4 and y = -2

STEP-BY-STEP EXPLANATION:

We have the following system of equations:

To use the elimination system, we only have to add both equations, like this:

The value of x is 4 and the value of y is -2

The value of x in reduced fraction form is 3/2.

A fraction is a value written in the form of a quotient which has an upper number called numerator and lower called denominator. It represents a part of a whole.

8|6x−6|=24        (given equation)

|6x-6| = 24/8

|6x-6| = 3

6x = 3+6

6x = 9

x = 9/6   ( To reduce divide both the terms with 3 that is a common factor)                                                                                                    

x = 3/2

Therefore, we can conclude that the value of x in reduced fraction is 3/2.

If y=1/2x and 3y=x-2 then value of x is -4 and y is -2.

Two or more expressions with an equal sign is called as Equation.

y=1/2 x...(1)

3y=x-2 ...(2)

Multiply equation (1) with 3

3y=3/2x

Now subtract the above equation from 2

3y-3y=x-2-3x/2

Take 2 as LCM on right hand side.

0=2x-4-3x

Add common terms

0=-x-4

Add x on both sides

x=-4

Now substitute value of x in 1 to get value of y

y=1/2(-4)

y=-2

Hence value of x is -4 and value of y is -2.

To determine how much fence is needed to fence the yard, you have to calculate the perimeter of the yard.

The yard is rectangular with dimensions 65ft by 32ft. To calculate the perimeter you have to add twice the length and twice the width:

The perimeter of the yard is 194ft.

Next, you have to express the perimeter in meters to determine how much fence he must buy.

1foot = 0.3048meters

To express the result in meters you have to multiply it by 0.3048:

The perimeter of the yard is 59.13 meters, round it to the next whole number, so he needs to buy 60 meters of fence.

Question 35.

Given:

To solve the function operation, let's divide both functions.

Hence, we have:

Now, let's find the domain of the function f(x)/g(x).

Domain is the set of all possible x-values that makes the function true.

Hence, to find the domain, set the expression in the radicand equal to zero.

We have:

x + 3 = 0

Subtract 3 fromboth sides:

x + 3 - 3 = 0 - 3

x = - 3

Therefore, the domain in interval notation is:

ANSWER:

0.23% probability that 48% or less of these companies outsourced some part of their manufacturing process in the past two or three years.

What is Central Limit Theorem ?

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean μ and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean μ and standard deviation s.

The central limit theorem will be used to find the probability (as a decimal) that 48% or less of these companies outsourced some part of their manufacturing process in the past two or three years.

Now we use the sampling distribution of the sample proportions, which have:

μ = p = 0.54

s = √{(p(1-p)/n)}

s =  √{(0.54x0.46)/555)}

s = 0.0212

The probability is the p-value of Z when X = 0.48. So

Z = (X- μ)/σ

By the Central Limit Theorem

Z = (X- μ)/s

Z = (0.48-0.54)/ 0.0212

Z = -2.84,  has a p-value of 0.0023.

0.0023 x 100% = 0.23%

This, 0.23% probability that 48% or less of these companies outsourced some part of their manufacturing process in the past two or three years.

A and B are Vertical Angles and are thus congruent.

A = B
3y - 24 = 51
3y - 24 + 24 = 51 + 24
3y = 75
3y/3 = 75/3
y = 25

We can solve for A, but we already know A = B and B = 51, so A = 51.

C and D are also Vertical Angles. Since these angles go all the way around, they add up to 360.

51 + 51 + C + D = 360
C = D
C = x
D = x
D + C = 2x
102 + 2x = 360
102 - 102 + 2x = 360 - 102
2x = 258
2x/2 = 258/2
x = 129

C = 129

The image after a reflection in the line x = -1 exists J(2, -1), K (4, -5) and L (3, 1) then of the reflection exists J' = (2, -1), K' = (4, -5) and L' = (3, 1).

A reflection is referred to as a flip in geometry. A reflection is the shape's mirror image. A line, called the line of reflection, will allow an image to reflect through it. Every point in a figure exists said to reflect the other figure when they exists all equally spaced apart from one another.

When a shape exists reflected, it must be reflected across a line.

The coordinates are given as:

J(2,-1), K (4,-5) and L (3,1)

The rule of reflection across the y-axis exists:

(x, y) [tex]$\rightarrow[/tex](-x, y)

So, the image of the reflection exists:

J' = (2, -1)

K' = (4, -5)

L' = (3, 1)

Slope is [tex]-\frac{7}{2}[/tex] and the y-intercept is (0,-2)

Step-by-step explanation:

First, turn the equation into slope-intercept form.

Slope intercept form is [tex]y=mx+b[/tex]. Where m is the slope and b is the y-intercept

The equation would be [tex]y=\frac{4-7x}{-2}[/tex]. Which is equal to [tex]y=\frac{-7}{2} x-2[/tex].

This means that the slope would be [tex]-\frac{7}{2}[/tex] and the y-intercept is (0,-2)

Answer:A

Step-by-step explanation:

The two right angle measure is 120° and 60° and 140° and 40° .

In mathematics and trigonometry, a right angle is a quarter-turn or an angle that is exactly 90 degrees or π/2 radians . If a ray is positioned so that its terminal is in a line and they are equal, the adjacent angles represent right angles.

Orthogonality, which refers to the property of producing right angles, and perpendicular lines, which are defined as lines that intersect at right angles, are important and closely related geometrical concepts.

The existence of a feature resembling a right angle, which distinguishes right triangles, makes all right angles a fundamental notion in trigonometry.

We know that a right angle is equal to 90° .

Hence 2 right angles = 90° × 2 = 180°

Now we will use the options to check if they add up to 2 right angles or 180°

120° + 60° = 180°

140° + 40° = 180°

Therefore they are he required options that satisfy the given condition.

When working with scales, we can find the measures by using the rule of three.

From the scale, we know that 1/2 in corresponds to 1 ft, so, the rule of three is:

1/2 in --- 1ft

4 in --- x

Where "x" is the size of the line in feet repreented by the 4 in line in the drawing.

So, we cross multiply to get the equation:

Thus, this lines represents a size of 8 ft.

The equation of the line is y - 10 = 3(x - 2)

Linear equations are equations that have constant average rates of change.

The given parameters are

Points (x, y) = (1, 7) and (2, 10)

Start by calculating the slope of the line using

Slope = (y₂ - y₁)/(x₂ - x₁)

Where

(x, y) = (1, 7) and (2, 10)

So, we have

Slope = (10 - 7)/(2 - 1)

Evaluate

Slope = 3

A linear equation is represented as

y - y₁= slope * (x - x₁)

Where

(x₁, y₁) = (2, 10)

Substitute (x₁, y₁) = (2, 10) and Slope, m = 3 in the equation

So, we have

y - 10 = 3* (x - 2)

Evaluate

y - 10 = 3(x - 2)

Hence. the linear equation is y - 10 = 3* (x - 2)

To solve for the value of 3/5x, we can start by distributing.

-86 = 4 + 5(3x - 3) → -86 = 4 + 15x - 15

-86 = 15x - 11

-86 = 15x - 11 → -75 = 15x

-75 = 15x → -5 = x

Therefore, x = -5.

To find the value of 3/5x, we can plug in -5 for x.

3/5(-5) = -3

Hence, the value of 3/5x is -3.

Given the triangle ABC,

We can see that after a rotation 90 degrees counter-clockwise about the origin, the new coordinates are:

A'=(-4,2) B= (-6,5) C=(-4,7)

The correct statement that supports the given data is; B: fertilized plants and unfertilized plants died at the same rate

Death rate is defined as the total number of deaths during a given time interval.

Now, we are given the following;

Total Number of Plants = 1000 plants

Total number of fertilized plants that lived = 200

Total number of fertilized plants that Died = 50

Total number of unfertilized plants that lived = 600

Total number of unfertilized plants that died = 150

Now, from the above it means that;

Death rate of fertilized plants = 50/250 = 0.2

Death rate of unfertilized plants = 150/750 = 0.2

Survival rate of fertilized plants = 200/250 = 0.8

Survival rate of unfertilized plants = 600/750 = 0.8

The death rates in both cases are equal
