In Order To Solve The System Of Equations {x-3y=2{2x+y=11Using The Elimination Method, Which Of The Following

Answers

Answer 1

Answer:

Multiply the second equation by 3 and then add result to the first equation

Step-by-step explanation:

Given the equations :

x-3y=2

{2x+y=11

To solve by elimination :

Multiply one of either equations by a number to give a result such that adding the result to the other equation in the system leads to the removal of one of the unknown values.

By Multiplying the second equation by 3 and then add result to the first equation

Second equation becomes :

6x + 3y = 33

Adding the result to the first equation :

x - 3y = 2

6x + 3y = 33

___________

7x = 35

_________

Here, the y variable has been eliminated

If you Start with $10 in the bank and each month you add $20 which line equation will give you your total amount after X months?

Answers

Answer:

y=20x+10

Step-by-step explanation:

You start with $10, so this will be added on, and is not affected by the number of months.

You add $20 each month, so the 20 is dependant on x.

1. Determining the probability of a coin landing heads up by actually tossing a coin several times is an example of what?


A. sample probability
B. theoretical probability
C. experimental probability
D. outcome probability

Answers

Answer:

C.

Step-by-step explanation:

Theoretical probability and Experimental probability are related in that theoretical probability is based on your reasoning (e.g. two sides; therefore, there is a 50% chance of heads), but experimental probability is where your numbers are based off of actual results (e.g. you landed head 1/4th of the time; therefore, there is a 25% chance of getting heads.)

Answers

The answer would be option 2

Answer:

[tex]\frac{4}{5} .\frac{4}{5} .\frac{4}{5} =\frac{64}{125}[/tex]

Step-by-step explanation:

An "exponential form" is being used for "repeated multiplication." The value of [tex](\frac{4}{5} )^3[/tex] is equal to [tex]\frac{4}{5}[/tex] being repeatedly multiplied by itself.

[tex]\frac{4}{5}[/tex] x [tex]\frac{16}{25}[/tex] x [tex]\frac{4}{5}[/tex] = [tex]\frac{64}{125}[/tex]

Choice A is incorrect because it is an addition of fraction and also an incorrect way of adding the numerators. Choice C is also incorrect because it also used the addition operation. Choice D is incorrect because it repeatedly multiplied the reciprocal of [tex]\frac{4}{5}[/tex], which is [tex]\frac{5}{4}[/tex], instead of the fraction itself.

1 Rose factored the expression below. Is her answer correct? Why or why not? x2.5x + 6 + (x - 1)(x - 6)​

Answers

Answer:

(x+3)(x+2)

Step-by-step explanation:

Given the quadratic equation x²+5x + 6

Factorize

x²+2x+3x+6 = 0

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

(x+3)(x+2)

Hence the factored form is (x+3)(x+2)

A certain forest covers an area of 2100 km^2. Suppose that each year this area decreases by 5.25%. What will the area be after 6 years

Answers

Answer:

The area after 6 years is [tex]1519.49km^2[/tex]

Step-by-step explanation:

Given

[tex]a = 2100[/tex] --- Initial Value

[tex]r = 5.25\%[/tex] --- Rate

Required

Determine the area after 6 years

Because the area reduces,, the following formula will be used to solve the question.

[tex]y = a*(1 - r)^t[/tex]

Here

[tex]t = 6[/tex]

So, we have:

[tex]y = 2100*(1 - 5.25\%)^6[/tex]

Convert percentage to decimal

[tex]y = 2100*(1 - 0.0525)^6[/tex]

[tex]y = 2100*(0.9475)^6[/tex]

[tex]y = 1519.47866516[/tex]

[tex]y = 1519.49[/tex] -- approximated

The area after 6 years is [tex]1519.49km^2[/tex]

Given

Area = 212in²

Substitute

212 = πr²

r² = 212/3.14

r² = 67.52

r = √67.52

r = 8.22in

Answer:

  y = 6·2^x

Step-by-step explanation:

The general form can be written as ...

  y = a·b^x

The value of 'a' is the value of y when x=0. That is 6.

The value of 'b' is the ratio of y-values when x differs by 1. b = 12/6 = 2.

So, the equation of interest is ...

4 7/8 in decimal form

Answers

Answer:

4.875?

convert it into an improper fraction

4 7/8 in decimal form is equal to 4.875.

To convert the mixed number 4 7/8 into decimal form, we need to add the whole number part to the fraction part.

The whole number part is 4.

To convert the fraction 7/8 into decimal form, divide the numerator (7) by the denominator (8):

= 7 ÷ 8

= 0.875

Now, add the decimal result to the whole number:

= 4 + 0.875

= 4.875

Therefore, 4 7/8 in decimal form is equal to 4.875.

could you help me understand cross sections of three-dimenstional object its harder than it sound.​

Answers

A section, or cross-section, is a view of a 3-dimensional object from the position of a plane through the object. A section is a common method of depicting the internal arrangement of a 3-dimensional object in two dimensions. It is often used in technical drawing and is traditionally crosshatched.

Cross sections of three-dimensional objects are two-dimensional shapes of various sizes. They may be parallel to a side or base of the object or at an angle to these surfaces. A cross section may resemble the shape of the object’s side or base, or it may have a completely different shape.

what is the cost of one small box of grape fruit and one large box of grapefruit

Answers

Answer:

small box costs $11, large box costs $13

Step-by-step explanation:

2S + 3L = 61

3S + 3L = 72

Eliminate the L terms: subtract first equation from second equation

2S + 3L = 61

-3S - 3L = -72

-------------------

-S = -11

S = 11

2S + 3L = 61

2(11)+3L  = 61

3L = 39

L = 13

Answers

Answer:

3.5?

Step-by-step explanation:

The best estimate for the rate of change of the voltage over the interval will be 3.5 volts. Then the correct option is B.

What is the average rate change of a function?

It is the average amount by which the function is modified per unit throughout that time period. It is calculated using the gradient of the line linking the interval's ends on the graph that represents the function. The average rate of change of the function is given as,

Average rate = [f(x₂) - f(x₁)] / [x₂ - x₁]

The graph shows the voltage in a circuit changing as temperature increases from 100° to 600°.

We know that v = 1750 at t = 600° and v = 0 at t = 100°. Then the Average rate of change is given as,

Average rate = (1750 - 0) / (600 - 100)

Average rate = 1750 / 500

Average rate = 3.5

The best estimate for the rate of change of the voltage over the interval will be 3.5 volts. Then the correct option is B.

Suppose that a scientist captures 20 fiddler crabs in a small freshwater pond and marks them before releasing them back to the pond. The following week, the scientist returns and captures 30 fiddler crabs, six of which are marked. What is the estimated size of the fiddler crab population

Answers

Answer:

100 fiddler crabs

Step-by-step explanation:

If the 30 crabs are a representation of the entire population, then 6 marked crabs in a population of 30 would mean that

6 / 30 = 0.20 or 20%

20% of the entire crab population are marked. Since we know that a total of 20 fiddler crabs are marked in the pond then we can divide this number of marked crabs by 20% in decimal form to get the estimated total size of the fiddler crab population

20 / 0.20 = 100 fiddler crabs
