Using elimination method, the solution of the equation is as follows:

System of equation can be solved using different method such as elimination method, substitution method and graphical method.

Therefore, let's use elimination method to solve the equation as follows;

x + 4y = 22

4x + y = 13

multiply equation (i) by 4 to eliminate variable x.

Therefore,

4x + 16y = 88

4x + y = 13

subtract equation(ii) from equation(i)

15y = 75

divide both sides by 15

y = 5

x = 22 - 4y

x = 22 - 4(5)

x = 22 - 20

x = 2

The linear equation we want to write is:

18*x = 109

And the solution is x = 6.06

Remember that the product between two numbers is just a multiplication A*B.

Here we know that the product of 18 and a number, is 109.

If we define the variable x as the number, then we can write the linear equation:

18*x = 109

Where the product between 18 and x is equal to the number 109.

Now, we want to find the value of x, to do that, we need to divide both sides of the equation by 18, then we will get:

18*x/18 = 109/18

x = 109/18 = 6.06

The solution of the linear equation is 6.06

Step-by-step explanation:

Knowing that they are traveling 60 miles per hour, 60h is equivalent to how many miles they are traveling. When adding 300 you know that would be the a1 term going along the rules of sequences.

Therefore 60h is the rate of increase.

300 is the miles traveled on the first day.

With this information in mind we can now answer the True and false statements.

1. 5 represents the hours they drove on the first day, therefore 1 is a false statement.

2. 60 represents the mph they are traveling on the second day, therefore 2 is a false statement.

3. 300 represents the miles they traveled on the first day, therefore 3 is a true statement.

Step-by-step explanation:

a) Domain is all of the x-values that are defined in the function. The smallest x-value in the graph is -9, and the largest is 8. And all values in between are defined (have corresponding y-values). But notice that there's an open dot on (8,0).

b) Range is found the same way as Domain, but with the y-values. The smallest y-value of this function is -5, and the largest is 5.

For c-e, notice where the graph changes direction and draw a vertical line from the x-axis through the turning point. These lines are the boundaries between intervals of increasing/decreasing/constant. You should have vertical lines at x=-4, x=0, x=1, and x=6.

c) Interval(s) on which f(x) is increasing: Reading the graph from Left To Right, between which vertical lines is the graph going up?

d) Interval(s) on which f(x) is decreasing: Reading the graph from Left To Right, between which vertical lines is the graph going down?

e) Interval(s) on which f(x) is constant: Reading the graph from Left To Right, between which vertical lines is the graph staying flat?

The division between 756 and 26 can be represented as a fraction or decimal as 378/13 or 29.1 respectively

Fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.

We can say the fraction of a number is a ratio between the numerator and denominator of two numbers.

Fractions are often as a result of dividing two numbers and they probably don't give a whole number.

In this case, the division between 756 and 26 will result in a fraction because both numbers are not completely divisible by one another.

To divide 756 by 26;

756 ÷ 26 =

Divide both sides by 2

756 ÷ 26 = 378 / 13

Both numbers are not divisible by one another from here, but we can represent this as a fraction of one another;

The profit function is P(x) = −0.5x² + 40x - 100

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

Cost function, C(x) = 50x + 100

Revenue function, R(x) = −0.5(x − 90)² + 4050

The profit function is the difference between the revenue and the cost

So, we have

P(x) = R(x) -CP(x)

Substitute the known values in the above equation, so, we have the following representation

P(x) = −0.5(x − 90)² + 4050 - 50x - 100

Evaluate the like terms

P(x) = −0.5(x − 90)² - 50x   + 3950

Expand

P(x) = −0.5(x² − 180x + 8100) - 50x   + 3950

Expand

P(x) = −0.5x² + 90x - 4050 - 50x   + 3950

Evaluate the like terms

P(x) = −0.5x² + 40x - 100

In (a), we have

P(x) = −0.5x² + 40x - 100

Using a graphing calculator, the reasonable domain is

3 < x < 75

So, the domain is 3 < x < 75

Here, we have

x = 40 or 50

So, we have

P(40) = -0.5(40)² + 40(40) - 100 = 700

P(50) = -0.5(50)² + 40(50) - 100 = 650

In (d), we have

P(40) = 700

P(50) = 650

The other roots of the cubic equation p(x) = 24·x³ - 46·x³ + 29·x - 6 are;

x = 1/2

x = 3/4

A cubic equation is an equation  that has 3 as the highest index.

The specified polynomial in the question is presented as follows;

P(x) = 24·x³ - 46·x² + 29·x - 6

The solution of the equation is; x =  (2/3)

Therefore, (x - 2/3) is a factor of the equation and we get;

(24·x³ - 46·x² + 29·x - 6) ÷ (x - 2/3)  has a remainder of 0

Dividing the above expression using long division, we get;

                    24·x²  - 30·x + 9

(x - 2/3)  [tex]{}[/tex]     |(24·x³ - 46·x² + 29·x - 6)

                        [tex]{}[/tex]                        9·x - 6

The other real roots of the specified equation can be found as follows;

The equation for the roots is; P(x) = 24·x³ - 46·x² + 29·x - 6 = 0

From the above long division, therefore;

24·x³ - 46·x² + 29·x - 6 = (24·x²  - 30·x + 9) × (x - 2/3) = 0

Which indicates; (24·x² - 30·x + 9) = 0 or (x - 2/3) = 0

The other solution are;

24·x³ - 30·x + 9 = 0

3·(·8·x² - 10·x + 3) = 0

8·x² - 10·x + 3 = 0

Solutions for the above equation in the form; a·x² + b·x + c = 0 can be obtained using the quadratic formula as follows;

The quadratic formula; x = [tex]\dfrac{-b\pm\sqrt{b^2 - 4\cdot a\cdot c} }{2\cdot a}[/tex]

By comparing the equation, 8·x² - 10·x + 3 = 0 to the equation, a·x² + b·x + c = 0, we get;

a = 8, b = -10, and c = 3

Therefore;

x = (10 ± √((-10)² - 4 × 8 × 3))/(2 × 8)

((-10)² - 4 × 8 ×3) = 2

Therefore;

x = (10 ± √((-10)² - 4 × 8 × 3))/(2 × 8) = (10 ± 2)/(16)

x = 3/4, and x = 1/2

Therefore, the other other roots in increasing sequence are;
