solve -3x+2y=-6 -2x+y=6 using substitution

Answers

Answer:

See below

Step-by-step explanation:

-3x+2y = -6 [1]

-2x + y = 6 [2]

For [1], solve for X.

-3x + 2y = -6

-3x = -6 - 2y

3x = 6 + 2y

x = 2 + (2/3)y

Plug x into [2]

-2(2+(2/3)y) + y = 6

-4 - 4/3y + y= 6

-4/3y + y= 10

-1/3y = 10

y = -30

Answer:

  (x, y) = (-18, -30)

Step-by-step explanation:

When choosing to solve by substitution, it is convenient if one of the variables has a coefficient of 1 or -1. Here, y has a coefficient of 1 in the second equation, making it easy to rearrange that equation to give an expression for y:

  y = 2x +6 . . . . . add 2x to the second equation

Using this expression, we can substitute for y in the first equation:

  -3x +2(2x +6) = -6

  x + 12 = -6 . . . . . . . . . simplify

  x = -18 . . . . . . . . . . . subtract 12

  y = 2(-18) +6 = -30 . . . . substitute into the equation for y

The solution is (x, y) = (-18, -30).

Answer: f(x) = 6x+1/3

===============================

Explanation:

To find the original function from the inverse which is y = 3x-1/6, you replace the y with the x and then solve for y in terms of x.

1) x = 3y-1/6
2) 6x = 3y-1
3) 6x+1 = 3y
4) (6x+1)/3 = y

So therefore, your original function must be f(x) = 6x+1/3

13% VAT is levied on a handicraft after 10% discount. If the VAT amount is Rs 910, then find the marked price and selling price of it with VAT.​

Answers

Answer:

The marked price was $ 7,777.77, and the selling price of it with VAT was $ 7,910.

Step-by-step explanation:

Given that 13% VAT is levied on a handicraft after 10% discount, if the VAT amount is $ 910, to find the marked price and selling price of it with VAT the following calculations must be performed:

13 = 910

100 = X

100 x 910/13 = X

91,000 / 13 = X

7000 = X

0.9 = 7000

1 = X

7000 / 0.9 = X

7,777.77 = X

Therefore, the marked price was $ 7,777.77, and the selling price of it with VAT was $ 7,910.

A $210.00
B $659.40
C $340.69
D $681.38

Answers

Answer:

the right answer would be C

Answer:

Step-by-step explanation:

You first need to find the surface area of a completely open cylinder. That formula is

[tex]SA=2\pi rh[/tex] Using 3.14 for π, we find the area of the material that is needed to make this pipe:

SA = 2(3.14)(1)(30)

SA = 188.49 square feet.

If it costs $3.50 per square foot and you have 188.9 square feet, we multiply the cost per square foot times the number of square feet:

188.49(3.50) = $659.40, choice B.

Find on x on this triangle

Answers

Answer: correct answer is B.

Step-by-step explanation:

in the small triangle

taking 60 as reference angle

b = [tex]10\sqrt{3}[/tex]

so

tan 60 = p/b

[tex]\sqrt{3}[/tex] = p/([tex]10\sqrt{3}[/tex])

30 = p

so

[tex]h^2 = p^2 + b^2\\ = 30^2 + (10\sqrt{3} )^2\\\\ = 900 + 300\\ = 1200\\so h^2 = 1200\\then, h = \sqrt{1200} \\ = 20\sqrt{3} \\so\\in bigger triangle\\\\h = x[/tex](taking 45 as reference angle)

so

in bigger triangle

b = 20[tex]\sqrt{3}[/tex]

so

tan 45 = p/b

1 = p/(20[tex]\sqrt{3}[/tex])

p = 20[tex]\sqrt{3}[/tex]

so h^2 = p^2 + b^2

so

h^2 = (20[tex]\sqrt{3}[/tex])^2 +( 20[tex]\sqrt{3}[/tex])^2

= 1200 + 1200

h^2 = 2400

h =[tex]\sqrt{2400}[/tex]

=20[tex]\sqrt{6}[/tex]

so x = 20[tex]\sqrt{6}[/tex]

O B. y = 4x
O C. y = 2x
o D. y = 18x
O E y=-**
o E. y = - 3

Answers

Answer:

Step-by-step explanation:

If (8,2) and (0,0) are points on the line, the slope of the line is (2-0)/(8-0) = ¼.

y = ¼x

y = 1/4x is the equation of the  line passing through points (0, 0) and (8, 2)

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

slope of line passing through (0, 0) and (8, 2)

m=2/8

=1/4

Now let us find the y intercept in the equation.

2=1/4(8)+b

2=2+b

b=0

So equation will be y=1/4x.

If the average of b and c is 8, and d=3b-4, what is the average of c and d in terms of b?

Step-by-step explanation:

We are given (b+c)/2=8 and d=3b-4.

We are asked to find (c+d)/2 in terms of variable, b.

We need to first solve (b+c)/2=8 for c.

Multiply both sides by 2: b+c=16.

Subtract b on both sides: c=16-b

Now let's plug in c=16-b and d=3b-4 into (c+d)/2:

([16-b]+[3b-4])/2

Combine like terms:

(12+2b)/2

Divide top and bottom by 2:

A survey of households in a small town showed that in 850 of 1,200 sampled households, at least one member attended a town meeting during the year. Using the 99% level of confidence, what is the confidence interval for the proportion of households represented at a town meeting?

Answers

Answer:

Hence the confidence interval is ( 0.6745, 0.7422).

Step-by-step explanation:

Now the given are  

Sample size = n = 1200  

x = 850  

Sample proportion is  

[tex]\hat{p}=\frac{x}{n}=\frac{850}{1200}=0.7083[/tex]  

We have to construct 99% confidence interval for the population proportion.  

Formula Used:  

[tex](\hat{p}-E , \hat{p}+E)[/tex]  

Here E is a margin of error.  

[tex]E =Zc\times\sqrt{\frac{\hat{p}(1-\hat{p})}{n}}[/tex]  

Zc = 2.58  

[tex]E =2.58\times\sqrt{\frac{0.7083*(1-0.7083)}{1200}}\\\\E=2.58\times\sqrt{0.000172}=0.0339[/tex]  

So confidence interval is ( 0.7083 - 0.0339 , 0.7083 + 0.0339)

                                            = ( 0.6745 , 0.7422).

d. The field goal percentage for the Eagles was of 34.43%.

e. The Lions scored 96 points.

f. The Eagles scored 64 points.

g. Lions

Step-by-step explanation:

a. What is the free throw percentage for the Lions?

10 out of 16, so:

10*100%/16 = 62.5%.

The free throw percentage for the Lions is of 62.5%.

b. What is the free throw percentage for the Eagles?

10 out of 27, so:

10*100%/27 = 37.04%

The free throw percentage for the Eagles was of 37.04%.

c. What is the field goal percentage (two-point and three-point shots combined) for the Lions?

25 + 12 = 37 out of 50 + 16 = 66. So

37*100%/66 = 56.01%.

The field goal percentage for the Lions was of 56.01%.

d. What is the field goal percentage (two-point and three-point shots combined) for the Eagles?

9 + 12 = 21 out of 44 + 17 = 61. So

21*100%/61 = 34.43%

The field goal percentage for the Eagles was of 34.43%.

e. How many points did the Lions score?

10 free throws, 25 two's and 12 three's. So

Step-by-step explanation:

it is found that 4% of watches produced at a particular factory are defective. If 20 watches made at this factory are randomly selected, what is the probbility that at mpst 1 watch in the same sample is found to be defective

Answers

Answer:

0.81 = 81% probability that at most 1 watch in the sample is defective.

Step-by-step explanation:

For each watch, there are only two possible outcomes. Either it is defective, or it is not. The probability of a watch being defective is independent of any other watch, which means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

4% of watches produced at a particular factory are defective.

This means that [tex]p = 0.04[/tex]

20 watches made at this factory are randomly selected

This means that [tex]n = 20[/tex]

What is the probability that at most 1 watch in the same sample is found to be defective?

This is:

[tex]P(X \leq 1) = P(X = 0) + P(X = 1)[/tex]

In which

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 0) = C_{20,0}.(0.04)^{0}.(0.96)^{20} = 0.442[/tex]

[tex]P(X = 1) = C_{20,1}.(0.04)^{1}.(0.96)^{19} = 0.368[/tex]

Then

[tex]P(X \leq 1) = P(X = 0) + P(X = 1) = 0.442 + 0.368 = 0.81[/tex]

0.81 = 81% probability that at most 1 watch in the sample is defective.

It is assumed that the time customers spend in a record store is uniformly distributed between 3 and 12 minutes. Based on this information, what is the probability that a customer will be exactly 7.50 minutes in the record store

Answers

Answer:

0% probability that a customer will be exactly 7.50 minutes in the record store.

Step-by-step explanation:

Uniform probability distribution:

An uniform distribution has two bounds, a and b.  

The probability of finding a value of at lower than x is:

[tex]P(X < x) = \frac{x - a}{b - a}[/tex]

The probability of finding a value between c and d is:

[tex]P(c \leq X \leq d) = \frac{d - c}{b - a}[/tex]

The probability of finding a value above x is:

[tex]P(X > x) = \frac{b - x}{b - a}[/tex]

The uniform distribution is a continuous distribution, which means that the probability of an exact outcome is zero.

Uniformly distributed between 3 and 12 minutes.

This means that [tex]a = 3, b = 12[/tex]

What is the probability that a customer will be exactly 7.50 minutes in the record store?

Continuous distribution, so:

0% probability that a customer will be exactly 7.50 minutes in the record store.
