What is the solution to this system of equations?
3x + 2y = 10
2x + 4y = 4
0 (4,-1)
O (4,1)
O (1,2)
O (-4,3)

Answers

Answer 1
You can use elimination for this one so you can say

-2(3x+2y=10)
+2x+4y=4

So you have

-6x-4y=-20
+2x+4y=4

So you have

-4x=16

So x=-4

And then you can plug x into any one of the equations and solve for y

2(-4)+4y=4

-8+4y=4

Add 8 on both sides to get

4y=12

y=3

So in ordered pair form your answer is (-4,3)

Step-by-step explanation:

Answer:

A. $8.75   B. $26.25

Step-by-step explanation:

To figure this out, multiply .25 by 35 to find out what 25% of 35 is. The answer is $8.75, meaning that the shorts are $8.75 cheaper than the original price.

To find the on sale price, subtract $8.75 from $35. The answer is $26.25, meaning that the on sale price is $26.25.

If the cost of a competing factor of production, such as a machine that also could do the job, rises. This would result in a shift in the demand for this factor out to the right and would put pressure on the wage to rise. I don't understand why this is the case because I thought if machines replaced human labor then wouldn't wages be lower because there wouldn't be a need for human labor?

Answers

Keep in mind that we're framing it based on what the first sentence says, which is "If the cost of a competing factor of production, such as a machine that also could do the job, rises".

So if the cost of getting a machine part, various parts, or the entire machine cost rises, then demand for the machine will go down. This will make employers seek out substitutes. In this case, those substitutes would be human labor. As employers demand for labor goes up, the wages will rise assuming the supply of workers is held constant. If the supply of workers increased, then you could argue the wages could go down. So that's why I'm assuming the supply is held in check.

O $5,040
$8,400
$4,200
$9,240

Answers

Answer:

$9,240.

Step-by-step explanation:

Given that in 2018, all salaries between $ 38,701 and $ 82,500 had to pay a federal income tax of 22%, and that my salary in that year was $ 42,000, to determine the amount that I had to pay in concept of said tax, the following calculation must be done:

(42,000 x 22) / 100 = X

924,000 / 100 = X

9,240 = X

Therefore, the amount of federal income tax that I had to pay in 2018 was $ 9,240.

The population of a particular type of bacteria is known to triple in 22 days. What is the daily growth rate

Answers

Answer: ∛(3)

Step-by-step explanation:

Suppose that at day 0 the population was A.

at day 3, the population will be: 3*A

at day 6, the population will be 3*(3*A) = A*3^2

then, at day N = 3*n (where n = 0, 1, 2.....) the population will be:

P(N) = A*3^n

Particularly, if we take n = 1/3 we will have:

N = 3*1/3 = 1

This means that this is the first day after the day 0.

P(1) = A*3^(1/3)

(then in day one, the population grow by a factor of 3^(1/3))

N = 2 is when n = 2/3, then:

P(2) = A*3^(2/3)

The quotient between P(2) and P(1) is equal to the growth between day one and day two, this should be the same as the growth between day zero and day one.

A*3^(2/3)/(A*3^(1/3)) = 3^( 2/3 - 1/3) = 3^(1/3)

So we found that the daily growth rate is 3^(1/3) or ∛(3)

The daily growth rate of the bacteria is an illustration of unit rates

The daily growth rate of the bacteria is 0.136

For 22 days, the population of the bacteria triples.

The daily rate is the amount of bacteria each day.

So, we have:

[tex]\mathbf{Daily = \frac{Rate}{Days}}[/tex]

This gives

[tex]\mathbf{Daily = \frac{3}{22}}[/tex]

Divide

[tex]\mathbf{Daily = 0.136}[/tex]

Hence, the daily growing rate of the bacteria is 0.136

The length of Line segment VZ is 10 units if Z is the circumcenter of triangle TUV. Point Z is the circumcenter of triangle T U V option (D) 10 units is correct.

What is the triangle?

In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have:

In the diagram, Z is the circumcenter of the triangle TUV. Point Z is the circumcenter of triangle T U V.

As we know, The vertices of a triangle are equidistant from the circumcenter.

VZ = UZ = TZ

UZ = 3x + 4

TZ = 5x

3x + 4 =5x

5x - 3x =4

2x = 4

x = 2

TZ = 5x = 5(2) = 10 units

Thus, the length of Line segment VZ is 10 units if Z is the circumcenter of triangle TUV. Point Z is the circumcenter of triangle T U V option (D) 10 units is correct.

Draco invests $5000. Approximately how long will it take for the investment to double if the rate is 10% compounded annually?

Answers

Answer:

I'm in 6th grade and I think it is 500

For the investment to double if the rate is 10% compounded annually,

it will take about 7 years and 3 months.

What is compound interest rate?

Compound interest is computed as interest on the principle of an account plus any accrued interest.

Compound interest can be calculated using the following formula:

x = P (1+r/n[tex])^{nt}[/tex]

,where x = compound interest

P = principal (the initial deposit or loan amount)

r = annual interest rate

n = the number of compounding periods per unit of time

t = the number of time units the money is invested or borrowed for.

Given:

Draco invests $5000.

Draco wants his investment to double.

That means, accrued amount = $10000

Interest rate = 10%

First, convert R as a percent to r as a decimal

r = R/100

r = 10/100

r = 0.1 per year,

Then, by using the formula,

t = ln(A/P) / n[ln(1 + r/n)]

t = ln(10,000.00/5,000.00) / ( 1 × [ln(1 + 0.1/1)] )

t = ln(10,000.00/5,000.00) / ( 1 × [ln(1 + 0.1)] )

t = 7.273 years

t = about 7 years 3 months

Therefore, the required time is about 7 years 3 months.
