FISRT RIGHT THEN EQUATION IN THE GENERAL FORM y=mx+c

y=-4-15x

In the y intercept the x coordinate in the axis is 0.

therefore we can plug in the value 0 in the place of x and solve for y

[tex]y = - 4 - 15(0) \\ y = - 4[/tex]

The y intercept is -4.

From the given statements, the statement which is true when comparing numbers using a number line is :

The number left is always the least.

The definition of a number line is a straight line that shows numbers arranged at equal distances.

A number line is often shown horizontally and can be extended indefinitely in any direction.

Moving right causes the numbers to increase (or become greatest), while moving left causes the numbers to decrease ( or becomes least).

Larger numerals on the number line are always to the left of smaller numbers. Positive numbers have a negative opposite, and negative numbers have a positive opposite. Because it is defined as the distance from zero (the origin) on a number line, the absolute value of any real number is always positive.

Hence the right statement is that the number left is always the least.

$ 807.76    is the balance after 3 years by compound interest.

What is compound interest with example?

Given

Principal , P = $675

Rate , r = 6% = 0.06

Time = t years

n = 12             (compounded monthly)

(a)

Balance after t years is given as,

A = P(1 + r/n)nt

A = 675(1 + 0.06/12)12t

A = 675(1.005)12t

Balance after t years =  675(1.005)12t              

(b)

Balance after 3 years =  675(1.005)12*3

= 675(1.005)36

= 675*1.19668

=807.7593 \approx 807.76

Using proportions, it is found that:

A proportion is a fraction of a total amount, and the measures in the context of a problem are found using basic arithmetic operations such as multiplication and division.

One application of proportions is for ratio problems, as fractions are built from the ratios to find the equivalent amounts.

Caleb noticed that for every 10 orders of cheese pizza there were 7 orders of pepperoni pizza, 5 orders of sausage pizza and 8 orders of mushroom pizza, hence the fraction of Pepperoni pizzas out of the total is given by:

Pepperoni = 7/(10 + 7 + 5 + 8) = 7/30 of the total.

If 35 pepperoni pizzas were ordered, the total number is found as follows:

7x/30 = 35

7x = 30 x 35

x = 30 x 5

x = 150 pizzas.

2 out of every 25 pizzas were burned, hence the number of burned pizzas is given by:

2/25 x 150 = 2 x 6 = 12 pizzas.

The cheese fraction is given by:

10/30.

Hence, out of 360 pizzas, the number is given by:

10/30 x 360 = 10 x 12 = 120 cheese pizzas

The mushroom fraction is given by:

8/30.

Hence, out of 360 pizzas, the number is given by:

8/30 x 360 = 8 x 12 = 96 mushroom pizzas

The values of x that will make this expression equal to 0 are -1 and 9

Given the expression;

(x-9)(x+1)

Let's take the following steps to determine the values

First, expand the bracket, we get;

x² + x - 9x - 9

x² + x - 9x - 9

equate the expression to zero, we have;

x² + x - 9x - 9 = 0

add or subtract the like terms, we get;

x² - 8x - 9 = 0

Factorize the values

x² - 9x + x - 9 = 0

Factor out the common terms in the equation, we get;

x(x - 9) + 1(x - 9) = 0

The equation are;

x + 1 = 0 and x - 9 = 0

Then,

x + 1 = 0

x = -1

x - 9 = 0

x = 9

Thus, the values are - 1 and 9

Step-by-step explanation:

From the given dot plot, it is found that:

1. Farm 1 has mean of 8 inches and standard deviation of 1.15 inches, while Farm 2 has a mean of 8 inches but a standard deviation of 2.31 inches.

2. The lower standard deviation tells that the heights of the trees in Farm 1 are more uniform than in Farm 2.

A dot plot shows the number of times that each observation appears in a data-set.

Hence, at farm 1, the measures are given as follows:

6, 7, 7, 8, 8, 8, 9, 9, 10.

The mean is given by:

M = (6 + 2 x 7 + 3 x 8 + 2 x 9 + 10)/9 = 8 inches.

The standard deviation is given by:

S = sqrt[((6-8)² + 2 x (7-8)² + 3 x (8-8)² + 2 x (9-8)² + (10-8)²)/9] = 1.15 inches.

For Farm 2, the measures are given as follows:

4, 6, 6, 8, 8, 8, 10, 10, 12.

Hence the mean and the standard deviation are given, respectively, by:

Farm 1 trees' heights have a lower standard deviation than Farm 2 trees' heights, hence they have more uniform trees.

Step-by-step explanation:

The graph was horizontally stretched by a factor of 2.

For given data y varies directly with x and the constant of variation is 2.

And the equation is y = 2x

In this question, we have been given some values of x and y.

we need to determine whether y varies directly with x.

If so, find the constant of variation and write the equation.

x = -2, -4, -16

y = -4, -8, -32

Consider the ratio y/x

-4/-2 = 2

-8/-4 = 2

-32 / -16 = 2

As y/x ratio is constant, y varies directly with x.

and the constant of variation is 2.

Also, the equation from given x, y values would be,

y = 2x

Therefore, for given data y varies directly with x and the constant of variation is 2.

ATTACHED IS THE SOLUTION x=27°

Answer:

x = 27

Step-by-step explanation:

3x - 3 and 4x - 6 are same- side exterior angles and sum to 180° , that is

3x - 3 + 4x - 6 = 180

7x - 9 = 180 ( add 9 to both sides )

a) Number of points the team has  is 18

b) Number of games lost by the team is  9

a) How many point does the team have?

Number of wins the team has  = W= 5

Number of draws the team has  = D= 3

Number of points of the team = P

The equation is given by,

P = 3W +D

P= 3*5 + 3

P = 15+3

P = 18

Number of points the team has 18 points

b) How many games has this team lost?

Number of points of the team =P = 50

Number of draws the team has = D= 14

Number of wins the team has  = W

Number of matches played by the team =T= 35

The equation is given by,

P = 3W +D

50 = 3W+ 14

3W = 50- 14

3W = 36

W = 12

Rewriting as equation,

Lost matches = Total matches - (Win matches+ Draw matches)

                      = T - (W+ D)

                      = 35 - (12+ 14)

                      =35 - 26

                      = 9

Number of games lost by the team = 9

An additional strategy for splitting polynomials is synthetic division. If you are dividing by a polynomial of degree 1, it is a shortcut for long division that only functions in that situation.

The divisor often takes the shape of (x a). Contrary to long division, you are solely concerned with the polynomials' coefficients in synthetic division.

Another method for dividing a polynomial by the binomial x - c, where c is a constant, is synthetic division.

Setting up the synthetic division is the first step.

Bring the leading coefficient down to the bottom row in step two.

Step 3: Divide c by the amount that was just entered in the bottom row.
