The equation of line is 11y + 3x + 37 = 0

What is Equation of Line ?

The equation y = mx + c is the general equation of any straight line where m is the gradient of the line (how steep the line is) and c is the y -intercept (the point in which the line crosses the y -axis).

The given points are, (5, -6) and (-5, -2)

To find slope we have formula ,

m = (y2 - y1 ) / (x2 - x1)

where,

(x1, x2) = (5, -6) and,

(y1, y2) = (-5, -2)

Put the values in given formula of slope,

m = (-2 - (-5) ) / (-6 - 5)

m = (-2 + 5) / (-11)

m = - (3/11)

we get the slope, now to find the equation of line.

We know, the equation of the line with slope intercept is

y = mx + b

Now, for x and y value take any point and put it into this equation and find 'b'

let's take (-5, -2)

-2 = -(3/11) * -5 + b

-2 = 15/11 + b

-2 = (15 + 11b) / 11

-22 = 15 + 11b

-22 - 15 = 11b

-37 = 11b

b = -37/11

We got m = - 3/11 and b = -37/11

Now put these value in equation of line and form the equation

y = mx + b

y = -3/11 x - 37/11

11y = -3x - 37

3x + 11y + 37 = 0

Hence, the equation of line is 11y + 3x + 37 = 0

The greatest number of rows Silvia can plant as per given number of plants and condition is equal to 10.

As given in the question,

Silvia is going to plant 20 tomato plants and 30 bean plants.

Total tomato plants = 20

Total bean plants = 30

If Silvia would like to plant, the plants in rows where each row has the same number of tomato plants and each row has the same number of bean plants.

Then, the greatest number of rows Silvia can plant is equal to greatest common factor of 20 and 30.

20 = 2×2×5

30 = 2×3×5

Greatest common factor of 20 and 30 = 2×5 = 10

Therefore, the greatest number of rows Silvia can plant as per given number of plants and condition is equal to 10.

The age of Evelyn is 10.5 years finding by the properties of linear equation.

What is linear equation?

A linear equation in algebra is one that only contains a constant and a first-order (linear) component, like y=mx+b, where m is the slope and b is the y-intercept.

Let the age of James is x years.

The age of Evelyn is x - 2.5 years

Sum of age of Evelyn and James are x + x - 2.5 = 2x - 2.5

According to question,

2 x (2x - 2.5) = 57

=> 4x - 5 = 57

=> 4x = 57 - 5

=> 4x = 52

=> x = 52/4

=> x = 13

Age of James is 13 years and the age of Evelyn is 13 - 2.5 = 10.5 years.

The distance between C and D is 17.26 units

What is meant by distance?

Distance is a numerical or qualitative measurement of the distance between two objects or places. Distance can refer to a physical length or an estimate based on other factors in physics or common use (e.g. "two counties over"). Because spatial cognition is a rich source of conceptual metaphors in human thought, the term is frequently used metaphorically to mean a measurement of the amount of difference between two similar objects (such as statistical distance between probability distributions or edit distance between text strings) or a degree of separation (as exemplified by distance between people in a social network). The concept of a metric space is used in mathematics to formalize most such conceptions of measurement, both real and metaphorical.

Distance CD = √{(-9-8)² + (-6+3)²}

                      = √{(-17)² + (-3)²}

                      = √{289 + 9}

                      = √298

                      = 17.26 units

Hence, the distance between C and D is 17.26 units

The least polynomial that contains the roots - 1 and 3 - i is x³ - 5 · x² + 4 · x + 10.

In this case we need to find a polynomial that contains a set of roots, a real root and a complex root. In accordace to the quadratic formula, the root 3 - i must be accompanied by its conjugate, that is, 3 + i to guarantee that all coefficients of the polynomial are real.

Then, the factor form of the cubic equation is:

f(x) = (x + 1) · (x - 3 + i) · (x - 3 - i)

f(x) = (x + 1) · [x² - (3 - i) · x - (3 + i) · x + (3 - i) · (3 + i)

f(x) = (x + 1) · (x² - 3 · x + i x - 3 · x - i x + 9 - i²)

f(x) = (x +1) · (x² - 6 · x + 10)

f(x) = x³ - 6 · x² + 10 · x + x² - 6 · x + 10

f(x) = x³ - 5 · x² + 4 · x + 10

The least polynomial is x³ - 5 · x² + 4 · x + 10.

Speed = distance /time

Also, Time = distance/ speed

In this case, the distance is 4 laps of 400 meters, so;

4 x 400=1600 meters

Speed = 250 per minute

Now,

Time =1600 meters /250 meter per minute

The inequality representing d, the total number of days is 76.5d + 24 ≤ 330

From the question, the given parameters are:

Charges per day = $76.50

Charges per mile = $0.06

This means that the equation that represents the total charges for d days is

Total = Charges per day x Number of days + Charges per mile x Number of miles

So, we have

Total = 76.5 x d + 0.06 x m

Where m represents the number of miles

From the question, we have

This means that

m = 400 and Total ≤ 330

So, we have

76.5 x d + 0.06 x 400 ≤ 330

Solve

76.5 x d + 24 ≤ 330

a) the independent variable is the: Number of month after the first year

b) the dependent variable is the: Amount remaining on the card

To solve this problem, we have to state the equation using the information of the problem.

Information about the problem:

Writing the equation according to the information gave, we have:

y = 25 - (2.50x)

Where:

The relationship between the number of months after the first year and the amount remaining on the card is: linear and inverse because when the number of months after the first year increases (x), the amount remaining on the card (y) will decrease.

The "y" variable is the dependent variable, because it will change according to the number of months passed after the first year (x).

The "x" variable is the independent variable, because it doesn't depend on any other value, just the number of months passed after the first year.

The empty boxes of the numerators for the given rational expression is to be filled with 4x and 2 respectively.

Rational expression is a division of two polynomials. Which implies that the numerator and denominator of the fraction consists of polynomials.

To solve this, we will first factorise the expression of the denominator as follows;

x² - 9x + 8 = x² - 8x - x + 8

x² - 9x + 8 = x(x - 8) -1(x - 8)

x² - 9x + 8 = (x - 1)(x - 8)

Hence, we can rewrite the rational expression as:

(4x + 2)/[(x - 1)(x - 8)]

we can break the expression further by dividing each term of the numerator with the expression (x - 1)(x - 8) as follows;

(4x + 2)/[(x - 1)(x - 8] = [4x/(x - 1)(x - 8)] + [2/(x - 1)(x - 8)]

Therefore, 4x and 2 will be the appropriate values to be filled in the empty boxes equated to the rational expression.
