The equation of the line in slope-intercept form is y = (-2)x + (-3)  .

The equation of a line in slope-intercept form can be written as follows,

y = mx + c                                                       equation 1

m in the above equation represents slope of the line and c represents the intercept.

The given equation is 3y + 9 = -6x .

To get the equation of the line in slope-intercept form we need to convert the given equation in the format of equation of a straight line i.e., equation1. So, now we will rearrange the given equation as

3y + 9 = -6x

3y = -6x - 9

On dividing both sides of above equation by 3, we will get

y = (-2)x + (-3)                                                 equation 2

On equating equation 1  and equation 2, we will get

Slope of the line = m = -2

Intercept = c = -3

The equation of the line in slope-intercept form is y = (-2)x + (-3)  .

The rate of interest is 0.26%

Given,

The amount borrowed by Fred to start a new e-commerce business = $13100.

Time of investment = 13 years.

Interest for the money = $3916.90

We have to calculate the rate of interest.

For simple interest, equation is:

P = IRT

Where,

P = Principal amount

R = Rate of interest

I = Interest

T = Time period

Here,

P  = 13100

I = 3916.90

T = 13

Then,

R = P / IT

R = 13100 / (3916.90 × 13)

R = 13100 / 50919.7

R = 0.26%

Therefore, the rate of interest is 0.26%

The given series is a geometric series. The sum of its first 6 terms is 728.

To determine whether the series is an arithmetic or geometric one, we need to check how the consecutive terms relate to each other.

If it is an arithmetic series, then:

  a(n) = a(n-1) + d

where d is the common difference.

If it is a geometric series, then:

  a(n) = a(n-1) . r

where r is the common ratio.

The given series is:

     2+6+18+ . . . .

and the number of terms is 6.

In the given series:

a(1) = 2

a(2) = 6

a(3) = 18

Notice that

a(2)/a(1) = 6/2 = 3

a(3)/a(2) = 18/6 = 3

Since the ratio of consecutive terms are constant, then the given series is a geometric series. Furthermore, its ratio, r = 3

Sum formula for the first n term of a geometric series is:

S(n) = a(1) .  (rⁿ -1)/(r -1)

Substitute n = 6, a(1) = 2, and r = 3

S(6) = 2 . (3⁶ - 1)/(3 - 1)

S(6) = 2. 364

      = 728

We can also evaluate the sum directly. Write all the terms until n = 6.

a(4) = 18 . 3 = 54

a(5) = 54 . 3 = 162

a(6) = 162 . 3 = 486

Hence, the series is:

2+6+18+54+162+486 = 728

The value of x for the quadratic equation is  1.099 or -9.099 .

What is completing the square?

Completing the Square is a method used to solve a quadratic equation by changing the form of the equation so that the left side is a perfect square trinomial .

To solve ax²+bx+c=0 by completing the square:

1.  Transform the equation so that the constant term, c , is alone on the right side.

2.  If a , the leading coefficient (the coefficient of the x² term), is not equal to 1 , divide both sides by a .

3.  Add the square of half the coefficient of the x -term,  to both sides of the equation.

4.  Factor the left side as the square of a binomial.

5.  Take the square root of both sides.  (Remember: (x+q)²=r is equivalent to x+q= ±√ r.)

6.  Solve for x .

According to the question

Quadratic equation by completing the square

x² + 8x = 10  

As we will try to make complete square of left side

for that

we have to add   to both sides of the equation

As

a = 1

2ab = 8

b = 4

x² + 8x + 4² = 10 + 4²

By using the identity (  )

(x + 4)² = 10 + 16

(x + 4)² = 26

x + 4 = ±

x + 4 = ± 5.099  

x = 5.099 - 4

x = 1.099

or

x = -5.099 - 4

x = -9.099

Hence, The value of x for the quadratic equation is  1.099 or -9.099 .

The area of one of the slices is  54π square inches

The given parameters are

Diameter = 36 inches

Number of slices = 6

The pie represents take the shape of a circle

And the area (A) of a circle using the diameter (d) is

A= π(d/2)^2

Multiply the above area by 1/6 to get the area of a slice of the pie

So, we have

Area = 1/6 * π(d/2)^2

This means that the area of one of the slices is calculated by

Area = 1/6 * π(d/2)^2

Where

d represents the diameter of the pie i.e. d = 36 inches

So, we have

Area = 1/6 * π * (36/2)^2

After calling the parents, and explaining them the issue of smashed phone, they travelled at a speed of 2.223 m/s = 8.0028 km/hr

As per the question statement, we are given that we call our parents to explain our issue with having a smashed phone and your parents travel at 20000 meters in 2.5 hours. We are supposed to find out that how fast did the parents rush to get here. Basically we have to find their speed of travelling.

Before solving the question, we must be aware that what is speed.

[tex]speed = \frac{distance}{time}[/tex]

and distance and time should be in SI units.

Given distance = 20,000 meters

Given time = 2.5 hours

[tex]1 hour = 60 min\\2.5 hour = 2.5*60\\2.5 hour = 150 min[/tex]

[tex]1 min = 60 sec\\150 min = 150*60 sec\\150 min= 9000 sec[/tex]

Therefore given time = 9000 sec

Therefore speed = [tex]\frac{distance}{time} = \frac{20000}{9000}[/tex]

Speed= 2.223 m/sec

Hence they travelled at a speed of 2.223 meters per second

2.223 m/s = 8.0028 km/hr

Eight angles are formed when two parallel lines are intersected by a third line that intersects them at an acute angle, known as a transversal line. These angles interact in a number of ways, one of which is the same-side exterior. Both angles are on the same side of the transversal line, as indicated by the word "same-side," and both are "external," or "outside," of the parallel lines, as represented by the term "outside."

When a transversal crosses two parallel lines, it creates an angle between the lines and outside the lines on the same side. Because the alternate interior and alternate exterior angles are the same, and because linear pairs of angles are supplementary, the identical side angles are also supplementary.

If Betsy has a bag with three mint sticks, eight jelly treats, and nine fruit tart chews and she eats one piece every three minutes, the probability her first two pieces will be a fruit tart chew and a jelly treat is 18.9%.

The probability of her first two pieces being a fruit tart chew and a jelly treat can be calculated as follows,

First, we divide the expected outcomes by the total possible outcomes.

Total possible outcomes = 3(mint sticks) + 8(jelly treats) + 9(fruit tart chews) = 20

Hence,

Probability for fruit tart chew: 9 ÷ 20

Probability for jelly treat: 8 ÷ 19 (as one possibility is considered to be fruit tart chew)

The probability of her first two pieces to be fruit tart chew and jelly treat can be determined by multiplying the probability for fruit tart chew with the probability for jelly treat,

Probability = (9/20)(8/19)

Probability = 72/380 = 0.189

Converting into percentage,

Probability = 0.189 × 100 = 18.9%

Hence, the probability that her first two pieces will be a fruit tart chew and a jelly treat is equal to 18.9%.

The complete length of a rectangle's outside edge is known as its perimeter. The formula P=2l+2w, where l is the rectangle's length and w is its width, determines the perimeter P of a rectangle.

Given the perimeter of the rectangle = 398
