4x-y= -2
2х + Зу = 13

Answers

Answer:

x = 1/2

y = 4

Step-by-step explanation:

4x - y = -2     --------------------(I)

2x + 3y = 13 --------------------(II)

Multiply equation (I) by 3 and then add

(I)*3         12x - 3y = -6

(II)             2x  + 3y = 13           {Now add and so y will be eliminated}

               14x         = 7

                          x = 7/14

x = 1/2

Plugin x = 1/2  in equation (I)

[tex]4*\frac{1}{2}-y = -2[/tex]

  2 - y = -2

     -y  = -2 - 2

     -y = -4      

   y = 4

Answer:

x=1/2

y=4

Step-by-step explanation:

4x-y=-2

-y=-4x-2

y=4x+2

2x+3y=13

2x+3(4x+2)=13

2x+12x+6=13

14x=7

x=1/2

y=4x+2

y=4(1/2)+2

y=2+2

Y=4

Leah would like to earn at least $120 per month. She babysits for $5 per hour and works at an ice cream shop for $8 per hour. Leah cannot work more than a total of 20 hours per month. Let x represent the number of hours Leah babysits and let y represent the number of hours Leah works at the ice cream shop. How did you determine the pair(s) (x, y) that Leah could work to meet the given conditions in item 15?

Answers

Answer:

Babysitting= 13.3 hours

Icecream shop= 6.6 hours

Step-by-step explanation:

Step one:

let the hours for babysitting be x

and the hours for icecream shop be y

we are told that Leah would like to earn $120 monthly

She babysits for $5 per hour and

works at an ice cream shop for $8 per hour

5x+8y=120---------------1

Leah cannot work more than a total of 20 hours per month

x+y≤20-------------2

The system of equation for the situation is

5x+8y=120

x+y≤20

x=20-y

put x=20-y in eqn 1

5(20-y)+8y=120

100-5y+8y=120

3y=120-100

3y=20

y=20/3

y=6.6 hours

put y=6.6 in eqn 2

x+6.6≤20

x≤20-6.6

x=13.3hours

Laura borrowed $105,000 at a rate of 6% simple interest for 12 years. How much interest will Laura pay?
Group of answer choices

$75,600

$37,800

$180,600

$256,200

Answers

Answer:

Laura will pay an interest of  $75,600.

Step-by-step explanation:

Our formula: A = P(1 + rt)

Principal = $105,000

Rate = 6%

Time = 12 years

A (amount)= 105,000(1 + (0.06 × 12)) = 180,600

$180,600 - $105,000 = $75,600.

Danielle is making a quilt with triangles and squares. There are 4 colored triangles inside each square. The base and height of each triangle is x + 4 inches as shown. Which polynomial represents the area of the colored triangles in square inches?

Answers

Answer:

[tex](2x^2+16x+32)\ \text{sq. inches}[/tex]

Step-by-step explanation:

b = h = Base = Height of triangle = [tex](x+4)\ \text{inches}[/tex]

Area of one triangle

[tex]A=\dfrac{1}{2}bh=\dfrac{1}{2}(x+4)(x+4)[/tex]

There are 4 colored triangles so total area of the triangles is

[tex]4A=4\times \dfrac{1}{2}(x+4)(x+4)\\\Rightarrow 4A=2(x+4)^2\\\Rightarrow 4A=2(x^2+8x+16)\\\Rightarrow 4A=2x^2+16x+32[/tex]

The area of the colored triangles is [tex](2x^2+16x+32)\ \text{sq. inches}[/tex]

Determine the nth term rule and find the 45th term for the arithmetic sequence with a10=1 and d=−6.

Answers

Answer:

a(45) =-209

Step-by-step explanation:

a(n) = a +(n-1)d

d=-6

we have to get a1

By using:

a(10) = a1 +(10-1)-6=1

a(10) = a1 +(9)-6 =1

          a1  =1+54=55

So:a(45) = 55 +(45-1)-6=-209

A few years ago, a popular clothing store ran TV ads with people doing some amazing dancing. The dancers leaped high in the air and did flips over each other's backs. They were doing the Lindy Hop. The Lindy Hop has a long and interesting history. The Lindy Hop started in 1926 at the Savoy Ballroom in the Harlem neighborhood of New York City. It's a type of swing dance that grew from the earlier swing dances, the Breakaway and the Charleston. It's fast, fun, and full of spectacular moves. The Breakaway was renamed the Lindy Hop in 1927 in honor of Charles Lindbergh's famous flight across the Atlantic Ocean. As Lindy Hoppers tried to outperform each other, they invented new moves. In fact, the dance was banned from the main dance floor at the Savoy because the dancing took up too much space. But soon everyone wanted to dance the Lindy, so the owners of the club moved it to the main dance floor. The dance took off, and the famous back-to-back move was invented in which the woman flips over the man's back. After World War II (19391945), jazz music developed from swing into bebop that people no longer danced to. But in the 1980s, the Lindy Hop had a revival. Now there are Lindy Hop dance clubs in many cities in the United States and Europe. Read this essay and type the topic and thesis statement in the space provided.

The U.S. Supreme Court came to a decision not long ago about the proper application of the word use. Briefly, the case in point was about a man named John Angus Smith who traded a handgun for cocaine. The law under which Smith was charged provided for a much more severe penaltyknown as an enhanced penaltyif a gun was used in a drug-related crime than if no gun was involved. (In this case, the enhanced penalty was a mandatory thirty-year sentence; the unenhanced penalty was five years.)Justice Antonin Scalia argued that Smiths penalty should not be enhanced because he did not use the gun in the way that the writers of the law had in mind; he did not use it as a gun. Justice Sandra Day OConnor argued that the law requires only the use of a gun, not any particular kind of use. If you were a judge, would you vote with Scalia or with OConnor?
