c). EF and ED - Both are skew

d). Plane ABC and plane ABF - Both of the planes do  intersect at point AB

e). Plane AED and plane BFC - Both of the given planes are known to be parallel

if the ratio equality is accurate, parallel. If the lines are not parallel or if you can solve them as a system of simultaneous equations, the lines will intersect. If two crossing lines have a zero dot product, they are perpendicular.

If the lines are not parallel or intersecting, they are said to skew. Lines that are parallel never cross.

Answer: Cannot be factored

Step-by-step explanation:

= Factor Y^2x -y^x-20

= Cannot be factored

Answer:

60°

Step-by-step explanation:

As we can conclude from the equal measured side lengths, this is an equilateral triangle so all angles have equal measurement.

Since the sum of interior angles in a triangle is equal to 180 to find the measure of angle V we need to divide 180 by 3:

180 ÷ 3 = 60

Solving the  system of equations using the algebraic method gives x = 1 or x = -4

Given: y = x²+x-1 and y+2x=3

In order to solve the system of equations algebraically

First, rewrite y+2x=3 to make y the subject:

y = 3-2x

Then, equate the two y of the equations and solve for x:

x²+x-1 = 3-2x

x²+x-1-3+2x = 0

x²+3x-4 = 0      (factorize)

x²+4x-1x-4 = 0

(x-1)(x+4) = 0

x-1 = 0 or x+4 = 0

x = 1 or x = -4

Therefore, the solution of the system of equations is x = 1 or x = -4

I pick the algebraic method because it is easier, faster and more accurate

I can check my answer by substituting the values of x into the equation

Answer:

(-4, 11) and (1, 1)

Step-by-step explanation:

Given system of equations:

[tex]\begin{cases}y=x^2+x-1\\y+2x=3\end{cases}[/tex]

The solutions to the given system of equations are the points of intersection of the two graphs.

To solve the given system of equations algebraically, first rearrange the second equation to make y the subject:

[tex]\implies y=3-2x[/tex]

Substitute the found expression for y into the first equation:

[tex]3-2x=x^2+x-1[/tex]

Rearrange to a quadratic equation and factor:

[tex]x^2+3x-4=0[/tex]

[tex]x^2+4x-x-4=0[/tex]

[tex]x(x+4)-1(x+4)=0[/tex]

[tex](x+4)(x-1)=0[/tex]

Apply the zero-product property to solve for x:

[tex](x+4)=0\implies x=-4[/tex]

[tex](x-1)=0\implies x=1[/tex]

To find the y-values of the solutions, substitute the found x-values into the rearranged second equation:

[tex]x=-4 \implies y=3-2(-4)=11[/tex]

[tex]x=1\implies y=3-2(1)=1[/tex]

Therefore, the solutions to the given system of equations are:

By graphing, the solution of the system of equations is: (6, -2).

To solve the system of equations by graphing, plot each of the line of the equations, then find the coordinates of the point where both lines intersect. Where they intersect is the solution to the systems of equations.

Given the following equations:

x + 2y = 2

y = -x + 4

x + 2y = 2 can be rewritten as y = -1/2x + 1. The graph for x + 2y = 2 will intercept the y-axis at 1 and also has a slope of -1/2. (It is the red line in the image below).

The graph of y = -x + 4 will also have a slope of -1 and intercept the y-axis at 4. (It is the blue line in the image below).

The graph of the equations are shown below, and they intersect at (6, -2), which is the solution to the system of equations.

Answer:

  a. 3/2 meters

  b. 15/4 times as great

Step-by-step explanation:

You want the width of a rectangle that is 3/5 m² in area and 2/5 m long. You also want to know the factor by which the length is greater than the width.

The formula for the area of a rectangle is ...

  A = LW

Filling in the known values, we can solve for the length:

  3/5 m² = (2/5 m)·L

  L = (3/5)/(2/5) m = 3/2 m . . . . . . divide by the coefficient of L

The length of the rectangle is 3/2 meters.

The ratio of length to width is ...

  length/width = (3/2 m)/(2/5 m) = (15/10)/(4/10) = 15/4

The length is 15/4 times greater than the width.

After ≈16.61 years the population will increased by  times it's original amount.

What do you mean by population?

A population is the entire set of people in a group, whether that group is a country or a collection of people who share a certain trait. A population is the group of people from which a statistical sample is taken in statistics.

Given: If a population doubles every 5  years.

Assume,  'A' is the starting population, and 't' is the passing time in years.

Given the fact that a population doubles every five years, our population is growing exponentially, as per the question.

Here, the equation can be written as follows: [tex]A(t) = A(2)^{\frac{t}{5} }[/tex]                    (1)

We now need to determine when the population will have multiplied by 10 by that time.

Let's substitute [tex]A(t) = 10A[/tex]  in the above equation.

[tex]10A = A(2)^{\frac{t}{5} }[/tex]

[tex]10 = (2)^{\frac{t}{5} }[/tex]

Taking the natural log of both sides we get:

[tex]ln10 = \frac{t}{5} \times ln2[/tex]                        {[tex]ln(a)^n= nln(a)[/tex]}

2.3025 x 5 = t x 0.6931

[tex]t = \frac{2.3025}{0.6931}\\t = 16.6096[/tex]

Therefore, After ≈16.61 years the population will increased by  times it's original amount.

The equation in standard form is x - y = 9

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

Points = (8, –1) and (2, –5)

Point-slope form is y + 1 = (x – 8).

Recall that the point-slope form is y + 1 = (x – 8).

So, we have

y + 1 = (x – 8)

Open the brackets

y + 1 = x – 8

Subtract 1 from both sides

y = x - 9

Rewrite as

-x + y = -9

Multiply through by -1

x - y = 9

A total of 549 of people at the convention are bored by the cable news

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

Not bored = 122

Bored = 9/11 of the people

This means that

Not bored = 1 - Bored

So, we have

Not bored = 1 - 9/11

Evaluate

Not bored = 2/11

Recall that Not bored = 122

So, we have

2/11 * x = 122

Where x = the number of people

This gives

x = 122 * 11/2

Evaluate

x = 671

Recall that

Bored = 9/11 of the people

So, we have

Bored = 9/11 * 671

Evaluate

Bored = 549

x-intercept is (-250, 0) and y-intercept is (0, 100)

What is  x-intercept and  y-intercept

The x-intercept is where a line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis. Thinking about intercepts helps us graph linear equations.

First, find x-intercept

For x-intercept it means y = 0

observe the graph and see the blue line cuts the x-axis when y = 0

We see, x = -250

so, the x-intercept is = (-250, 0)

Now, same thing do to find y-intercept

For y-intercept it means x = 0

observe the graph and see the blue line cuts the y-axis when x = 0

We see, y = 100

so, the y-intercept is = (0, 100)

Therefore, x-intercept is (-250, 0) and y-intercept is (0, 100).

The results might be the result of an experimental or sampling error if the hypothesis indicates a link between the two factors. There is a relationship in the measured phenomena, but, if the null hypothesis is incorrect.
