y=mx+b (-6,-5) and (-4,-4)​

Answers

Step-by-step explanation:

We will put this in y=mx +b form so first calculate the slope

m= (-4)-(-5)/(-4)-(-6)

m= 1/2. So y= x/2. +b

Now just substitute the x and y values of either given point to calculate b

I will use (-4,-4)

-4= (1/2)(-4) +b

-4= -2 +b

b=-2

companies. After how many miles
are the total costs at the
OI two truck rental
two companies equal?
Company A:
Company B:
$20 per day plus $.70 per mile
$45 per day plus S .25 per mile

Answers

Set up the equation and solve for miles:


20 + 0.70m = 45 + 0.25m

Subtract 20 from both sides

0.70m = 25 + 0.25m

Subtract 0.25m from both sides

0.45m = 25

Divide both sides by 0.45

M = 55.56 miles


answer: 55.56 miles ( rounded to nearest hundredth’s)

What is Genetic drift?

Genetic drift refers to the random fluctuations in the number of offspring in a population.

Rabbits can exhibit several colors in their coats: black, white, tan, brown, red, and grey.

A disease randomly kills off most of the population and leaves only black and grey rabbits.

Future generations are only black or grey. We can see that the future rabbits have some common colors that are given by their parents.

So, this must be Genetic drift.

A rectangle has sides measuring (6x + 4) units and (2x + 11) units.

Part A: What is the expression that represents the area of the rectangle? Show your work.

Part B: What are the degree and classification of the expression obtained in Part A?

Part C: How does Part A demonstrate the closure property for polynomials?

Answers

Answer:

Down Here ↓↓↓

Step-by-step explanation:

Hello!

A)

The area of a rectangle is L * W.

Area = (6x + 4)(2x + 11)Area = 12x² + 8x + 66x + 44Area = 12x² + 74x + 44

B)

The degree of a polynomial is the value of the highest exponent. The degree of 12x² + 74x + 44 is 2, because 2 is the highest exponent.

C)

This demonstrates the closure property, as adding, subtracting, and or multiplying polynomials will give a polynomial.


The Rhythm Record Shop orders sixty-minute cassette tapes at $1.49 and CDs at $4.98. A total of 451
items were ordered and the total amount of the invoice is $1240.86. How many of each item were
ordered?

Answers

The number of sixty-minute cassette tapes ordered is 288 and the number of CDs ordered is 163.

What are the linear equations that represent this question?

1.49a + 4.98b = $1240.86 equation 1

a + b = 451  equation 2

Where:

a = number of sixty-minute cassette tapes ordered b = number of CDs ordered

How many CDs were ordered?

Multiply equation 2 by 1,49

1.49a + 1.49b = 671.99 equation 3

Subtract equation 3 from equation 1

568.87 = 3.49b

Divide both sides of the equation by 3.49

568.87 / 3.49

b = 163

Answers

The value of x by using the zero product property therefore option A is correct.

We have given that,

(x+3)(x+2)=0

we have to determine the technique that is most appropriate to use to solve each equation

What is the zero product property?

The Zero Product Property simply states that if ab = 0, then either a = 0 or b = 0 (or both).

Therefore we have

(x+3)=0 and (x+2)=0

This implies that,

x+3=0

x=-3 and (x+2)=0 this implies that x=-2

Therefore we get the value of x by using the zero product property therefore option A is correct.

Step-by-step explanation:

Jason is considering two different jobs that he has been offered and he likes the atmosphere and

other employees equally at both companies.

With the first job he would be an apartment property manager for AMLI Company. This job is

offering Jason an hourly rate of $19. 00 an hour plus a weekly bonus of $40 for each new tenant he

sets a one year lease up with. The company expects Jason to work all 52 weeks of the year and 40

hours per week. He was told he could expect to set up an average of 5 lease agreements for each

week that he works.

With the second job he would work as water treatment facility manager in Gwinnett County. He

would be paid an annual salary of $46,000 a year, there are no bonuses by he gets a week off.

Both companies deduct for Social Security (6. 2%), Medicare (1. 2%), State Income Tax (3%), and

Federal Income Tax (14%).

AMLI's individual health insurance costs $115 per month. Gwinnett County's health insurance is

only $25 per month for an individual.

Part A: Determine how much Jason will receive in one year after all deductions have been taken

for each company. Show your work neatly.

Answers

The amount of money that Jason will receive in one year after all deductions have been taken for each company is $30,780.5 and $32562.

What is the final amount?

With the first job, he would be an apartment property manager for AMLI Company.

This job is offering Jason an hourly rate of $19. 00 an hour plus a weekly bonus of $40 for each new tenant he sets a one-year lease-up with.

The company expects Jason to work all 52 weeks of the year and 40 hours per week.

He was told he could expect to set up an average of 5 lease agreements for each week that he works.

The amount after one year will be given by an equation

Let y be the amount, x be the number of hours in a week and z be the number of the week.

y = 19x + 40z

The total number of hours in a year will be

x = 2080

Then

y = 19 × 2080 + 40 × 52

y = $ 41,600

The amount after the deduction of Social Security (6. 2%), Medicare (1. 2%), State Income Tax (3%), and Federal Income Tax (14%) will be

→ 41,600 × 0.938 × 0.988 × 0.97 × 0.86

→ $ 32,160.5

The amount after the insurance will be

Amount = 32160.5 - 115 × 12

Amount = $ 30780.5

With the second job, he would work as a water treatment facility manager in Gwinnett County. He would be paid an annual salary of $46,000 a year, there are no bonuses and he gets a week off.

The amount after the deduction of Social Security (6. 2%), Medicare (1. 2%), State Income Tax (3%), and Federal Income Tax (14%) will be

→ 46,000 × 0.938 × 0.988 × 0.97 × 0.86

→ $ 35,562

The amount after the insurance will be

Let the number of the worker be 10. Then

Amount = 35,562 - 10 × 12 × 25

Amount = 35562 - 3000

Amount = $32562

summarize the following excerpt:At the moment when the ray of moonlight superposed itself, so to speak, upon that inward radiance, the sleeping Bishop seemed as in a glory. It remained, however, gentle and veiled in an ineffable halflight. That moon in the sky, that slumbering nature, that garden without a quiver, that house which was so calm, the hour, the moment, the silence, added some solemn and unspeakable quality to the venerable repose of this man, and enveloped in a sort of serene and majestic aureole that white hair, those closed eyes, that face in which all was hope and all was confidence, that head of an old man, and that slumber of an infant. There was something almost divine in this man, who was thus august, without being himself aware of it. Jean Valjean was in the shadow, and stood motionless, with his iron candlestick in his hand, frightened by this luminous old man. Never had he beheld anything like this. This confidence terrified him. The moral world has no grander spectacle than this: a troubled and uneasy conscience, which has arrived on the brink of an evil action, contemplating the slumber of the just. That slumber in that isolation, and with a neighbor like himself, had about it something sublime, of which he was vaguely but imperiously conscious. No one could have told what was passing within him, not even himself. In order to attempt to form an idea of it, it is necessary to think of the most violent of things in the presence of the most gentle. Even on his visage it would have been impossible to distinguish anything with certainty. It was a sort of haggard astonishment. He gazed at it, and that was all. But what was his thought? It would have been impossible to divine it. What was evident was that he was touched and astounded. But what was the nature of this emotion? The gleam of the moon rendered confusedly visible the crucifix over the chimney-piece, which seemed to be extending its arms to both of them, with a benediction for one and pardon for the other. Suddenly Jean Valjean replaced his cap on his brow; then stepped rapidly past the bed, without glancing at the Bishop, straight to the cupboard, which he saw near the head; he raised his iron candlestick as though to force the lock; the key was there; he opened it; the first thing which presented itself to him was the basket of silverware; he seized it, traversed the chamber with long strides, without taking any precautions and without troubling himself about the noise, gained the door, re-entered the oratory, opened the window, seized his cudgel, bestrode the window-sill of the ground-floor, put the silver into his knapsack, threw away the basket, crossed the garden, leaped over the wall like a tiger, and fled.
