-6x+6y=6
-6x+3y=-12

Answers

Answer 1

Answer:

x=5 and y=6

Step-by-step explanation:

Answer 2

Answer:

x=5, y=6

Step-by-step explanation:

-6x + 6y = 6

If we divide this by 6 (which we can do because it is an equation), we can simplify this by a lot.

-6x + 6y = 6

-x + y = 1 <-- NEW EQUATION #1

We can also simplify -6x + 3y = -12 by dividing everything by 3.

-6x + 3y = -12

-2x + y = -4 <-- NEW EQUATION #2

Substitution is fairly easy for this problem.

Isolate the variable

-x + y = 1

y = x + 1

Now substitute (x+1) for where you see y in the second equation.

-2x + (x + 1) = -4

-x + 1 = -4

x = 5

Now substitute 5 for x.

-(5) + y = 1

y = 6

Answers

Answer:

20in

Step-by-step explanation:

[tex]Length = 10*\frac{2in}{1ft} =20in[/tex]

2 inches = 1 foot for the scale factor then you would do 10x2 which equals 20 so the minivan is 20 inches for that scale drawing.

Jia has $44,000 in a savings account. The savings collect interest at a 6% annual rate that compounds every year. How much money will be in Jia's account after 2 years?

Answers

Answer:

the answer is ieff = 2% - 3.24%

ieff = - 1.24% = -0.0124

Therefore the money left after 1 year would be:

F = 44,000 * (1 – 0.0124)

F = 43,454.4

So the amount of money lost is:

lost = 44,000 - 43,454.4

lost = $545.6

Answer:

Step-by-step explanation:

The simplified base for the function given is 9.

What is a function?

A function in math is a rule or expression that defines a relationship between one variable (the input or independent variable) and another variable (the output or dependent variable). A function assigns to each input exactly one output.

Given that, a function f(x) = 2(∛27)²ˣ, we need to find its simplest base,

So,

f(x) = 2(∛27)²ˣ

= 2(3)²ˣ [∵ 3³ = 27, ∴ ∛27 = 3]

= 2(3²)ˣ

= 2(9)ˣ

Hence, the simplified base for the function given is 9.

Show that the lines
y = 4x + 2 and 8x + 2y = -3 are parallel

help pls asap ty ! ! !

Answers

Answer:

They intersect

Step-by-step explanation:

We can determine from their equations whether two lines are parallel by comparing their slopes. If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel.

Here we have two functions:

1) y = 4x + 2

2) 8x + 2y = - 3

   2y = - 8x - 3

   // divide both sides by 2

   y = - 4x - 1,5  

- 4 ≠ 4 , so these lines aren't parallel, maybe you wrote the assignment incorrect (e. g. if there would be " - " before 8 in the second function, those lines would be parallel), here they intersect.

How would I find the difference of 7/8 - 1/3 ?

Answers

Answer:

[tex]\frac{13}{24}[/tex]

Step-by-step explanation:

We have two fractions and are being asked to subtract them.

7/8 and 1/3 don't have the same denominator, so to do as so, we need to find the LCM of both denominators, multiply them to that, and do the same for the numerators.

So what is the LCM (Least Common Multiple) of 8 and 3?

24.

Therefore :

[tex]\frac{7 * 3}{8 * 3} - \frac{1*8}{3*8}[/tex]

[tex]\frac{21}{24} - \frac{8}{24}[/tex]

[tex]\frac{13}{24}[/tex]

Answer:

13/24

Step-by-step explanation:

1. Common denominator:

common denominator = 24

multiply bottom and top so from 8 to 24 is 8x3, so multiply by three and what you do to the bottom you do to the top so,

7/8: 8 x 3 = 24 and 7 x 3 = 21 so the new fraction is 21/24.

Do the same to the other fraction: 1/3 multiply top and bottom by 8 because 3 x 8 = 24.

1/3 = 8/24

Now just subtract:

21/24 - 8/24 = 13/24 (There is your answer)

Need help ASAP with all 3 Do the heart serve as a artery to push blood around the body? Read the following passage carefully before you choose your answer.The following is an excerpt from an autobiography written in the third person by Henry Adams, a prominent Bostonian.The chief charm of New England was harshness of contrasts and extremes of sensibilitya cold that froze the blood, and a heat that boiled itso that the pleasure of hatingone's self if no better victim offeredwas not its rarest amusement; but the charm was a true and natural child of the soil, not a cultivated weed of the ancients. The violence of the contrast was real and made the strongest motive of education. The double exterior nature gave life its relative values. Winter and summer, cold and heat, town and country, force and freedom, marked two modes of life and thought, balanced like lobes of the brain. (5)Town was winter confinement, school, rule, discipline; straight, gloomy streets, piled with six feet of snow in the middle; frosts that made the snow sing under wheels or runners; thaws when the streets became dangerous to cross; society of uncles, aunts, and cousins who expected children to behave themselves, and who were not always gratified; above all else, winter represented the desire to escape and go free. Town was restraint, law, unity. Country, only seven miles away, was liberty, diversity, outlawry, the endless delight of mere sense impressions given by nature for nothing, and breathed by boys without knowing it.Boys are wild animals, rich in the treasures of sense, but the New England boy had a wider range of emotions than boys of more equable climates. He felt his nature crudely, as it was meant. (10)To the boy Henry Adams, summer was drunken. Among senses, smell was the strongestsmell of hot pine-woods and sweet-fern in the scorching summer noon; of new-mown hay; of ploughed earth; of box hedges; of peaches, lilacs, syringas1; of stables, barns, cow-yards; of salt water and low tide on the marshes; nothing came amiss. Next to smell came taste, and the children knew the taste of everything they saw or touched, from pennyroyal and flagroot2 to the shell of a pignut and the letters of a spelling-bookthe taste of A-B, AB, suddenly revived on the boy's tongue sixty years afterwards. Light, line, and color as sensual pleasures, came later and were as crude as the rest. The New England light is glare, and the atmosphere harshens color. (15)The boy was a full man before he ever knew what was meant by atmosphere; his idea of pleasure in light was the blaze of a New England sun. His idea of color was a peony, with the dew of early morning on its petals. The intense blue of the sea, as he saw it a mile or two away, from the Quincy hills; the cumuli3 in a June afternoon sky; the strong reds and greens and purples of colored prints and children's picture-books, as the American colors then ran; these were ideals. The opposites or antipathies, were the cold grays of November evenings, and the thick, muddy thaws of Boston winter. With such standards, the Bostonian could not but develop a double nature. (20)Life was a double thing. After a January blizzard, the boy who could look with pleasure into the violent snow-glare of the cold white sunshine, with its intense light and shade, scarcely knew what was meant by tone. He could reach it only by education.Winter and summer, then, were two hostile lives, and bred two separate natures. Winter was always the effort to live; summer was tropical license.(1918)1Syringas are ornamental shrubs.2Pennyroyal is a mint plant; flagroot is the root of a particular herb.3Cumuli are thick clouds.In context, the word "drunken" (sentence 10) is best understood to mean (2 points)excitingconfiningconsumedfrighteningstupor-inducing One purpose ofwas to win popular support for the war.propagandarationingvolunteeringrecruitment 4 of 5) What is a good way to stay diversified?A.
