The graph equation

Pick any two points, we have:

[tex](x_1,y_1) = (1,1)[/tex]

[tex](x_2,y_2) = (3,1)[/tex]

Calculate slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{1 - 1}{3 - 1}[/tex]

[tex]m = \frac{0}{2}[/tex]

[tex]m = 0[/tex]

The equation is then calculated using:

[tex]y = m(x - x_1) + y_1[/tex]

This gives:

[tex]y = 0* (x - x_1) + 1[/tex]

[tex]y = 1[/tex]

Hence, the equation is:

save your group money! If the total bill to get into the carnival was $100, how much does one
regular price ticket cost?
Write the equation and solve:

Answers

Answer:

The regular cost of each ticket is $30

Step-by-step explanation:

Hi,

You and three friends means there was a total of 4 people. Your equation is...

4x - 20 = 100

Remember to add the -20 since there was a coupon that saved you $20.

Now solve...

4x - 20 = 100

+ 20 on both sides

4x = 120

Divide by 4 on both sides

x = 30

The regular cost of each ticket is $30

Hope this helps :)

Given the equation Square root of 2x plus 1 = 3, solve for x and identify if it is an extraneous solution

Answers

To answer the question above, raise both sides of the equation to the power of two.
(sqrt (2x + 1))² = 3²
This will simplify into,
2x + 1 = 9
Solving for the value of x gives an answer of x = 4. This value is not an extraneous root as it satisfy the original equation even if it is inside the radical sign. (I hope this is right)

A student graphed an ordered pair on a coordinate plane that was located on the y axis and was 5 units above the origin. Write the ordered pair that the student graphed with these characteristics.​

Answers

A linear equation is an equation with two variables whose graph is a line. The graph of the linear equation is a set of points in the coordinate plane that all are solutions to the equation. If all variables represent real numbers one can graph the equation by plotting enough points to recognize a pattern and then connect the points to include all points.
If you want to graph a linear equation you have to have at least two points, but it's usually a good idea to use more than two points. When choosing your points try to include both positive and negative values as well as zero.
Example
Graft the function y = x + 2
Begin by choosing a couple of values for x e.g. -2, -1, 0, 1 and 2 and calculate the corresponding y values.
X Y = x + 2 Ordered pair
-2 -2 + 2 = 0 (-2, 0)
-1 -1 + 2 = 1 (-1, 1)
0 0 + 2 = 2 (0, 2)
1 1 + 2 = 3 (1, 3)
2 2 + 2 = 4 (2, 4)
Now you can just plot the five ordered pairs in the coordinate plane

At the moment this is an example of a discrete function. A discrete function consists of isolated points.
By drawing a line through all points and while extending the line in both directions we get the opposite of a discrete function, a continuous function, which has an unbroken graph.
picture14
If you only want to use two points to determine your line you can use the two points where the graph crosses the axes. The point in which the graph crosses the x-axis is called the x-intercept and the point in which the graph crosses the y-axis is called the y-intercept. The x-intercept is found by finding the value of x when y = 0, (x, 0), and the y-intercept is found by finding the value of y when x = 0, (0, y).
picture15
The standard form of a linear equation is
Ax+By=C,A,B≠0

Before you can graph a linear equation in its standard form you first have to solve the equation for y.
2y−4x=8

2y−4x+4x=8+4x

2y=4x+8

2y2=4x2+82

y=2x+4

From here you can graph the equation as we did in the example above.
The graph of y = a is a horizontal line where the line passes through the point (0, a)
picture16
Whereas the graph of x = a is a vertical line that passes through the point (a, 0)

1) -6, 0, 4
2) 6, 0, -4
3) -6, 0, -4
4) 6,0, 4

Answers

f(x) = x³ - 2x² - 24x

x³ - 2x² - 24x = 0

x(x² - 2x - 24) = 0

x = 0

x² - 2x - 24 = 0

a = 1, b = -2, c = -24

Delta = (-2)² - 4 * 1 * (-24) = 4 + 96 = 100

Assume that theta is a positive acute angle.

Given: sin theta=40/41
Find: cos2theta

SHOW YOUR WORK. First correct answer gets Brainliest.

Answers

By utilizing trigonometric identities,we got cos 2θ = -1519/1681.

Given that sin θ = 40/41 and θ is a positive acute angle, we can find cos θ using the Pythagorean identity sin²θ + cos²θ = 1. Rearranging the equation, we have cos²θ = 1 - sin²θ.

Substituting the given value, we get cos²θ = 1 - (40/41)² = 1 - 1600/1681 = 81/1681.

Now, we can find cos 2θ using the double-angle identity cos 2θ = cos²θ - sin²θ.

Substituting the known values, we have

cos 2θ = (81/1681) - (40/41)² = 81/1681 - 1600/1681 = -1519/1681.

Therefore, cos 2θ = -1519/1681.

A store is having a sale on trail mix and jelly beans. For 5 pounds of trail mix and 3 pounds of jelly beans, the total cost is $18. For 2 pounds of trail mix and 12 pounds of jelly beans, the total cost is $45. Find the cost for each pound of trail mix and each pound of jelly beans.

Answers

The store is at least 4

The cost for each pound of trail mix is $1.5 and each pound of jelly beans is $3.5 .

What is elimination method?

The elimination method is the process of eliminating one of the variables in the system of linear equations using the addition or subtraction methods in conjunction with multiplication or division of coefficients of the variables.

According to the question

A store is having a sale on trail mix and jelly beans .

Let trail mix = T

and  jelly beans = J

For 5 pounds of trail mix and 3 pounds of jelly beans, the total cost is $18.

i.e

5T + 3J = 18 -------------------------- (1)

For 2 pounds of trail mix and 12 pounds of jelly beans, the total cost is $45.  

i.e

2T + 12J = 45 -------------------------------(2)

Now,

multiplying eq (1) from 4

20T + 12J = 72 -----------------(3)

Solving equation (3) and (2) the equation by elimination method

20T + 12J = 72 -----------------(3)

2T + 12J = 45  -------------------------(2)

subtracting equation (2) from (3)

18T = 27

T = 1.5

substituting the value of T in equation 1

5T + 3J = 18

5*1.5 + 3J = 18

7.5 + 3J = 18

3J = 18 - 7.5

3J = 10.5

J = 3.5

Hence, the cost for each pound of trail mix is $1.5 and each pound of jelly beans is $3.5 .
