Answer 1
3xy+x=9
3xy = 9 - x
    y = 3/x - 1/3

if x = 2
f(2) = 3/2 - 1/3
f(2) = 9/6 - 2/6
f(2) = 7/6

if last years sales were $200,000 and this years increase was 250% how much are this years sales

Answers

This years sales is 240,000 dollars





Answer:

$700000

Step-by-step explanation:

We are given that last year sales=$200,000

This year sales  increases=250%

We have to find the earn money from this year sales

Let x be the earn money in this year

According to question

[tex]\frac{250}{100}\times 200000+200000=x[/tex]

[tex]x=500000+200000=700000[/tex]

A rectangular athletic field is twice as long as it is wide. if the perimeter of the athletic field is 192 ​yards, what are its​ dimensions

Answers

P = 2(L + W)
P = 192
L = 2W

192 = 2(2W + W)
192 = 2(3W)
192 = 6W
192/6 = W
32 = W <=== the width is 32 yards

L = 2W
L = 2(32)
L = 64 <=== the length is 64 yards

If h(x) = 5 for the function h(x) = 2x + 1, what is the value of x?

Answers

Well since h(x) = 5 and h(x) = 2x+1, we know that 5 = 2x+1. Now we just solve.

5 = 2x+1
4 = 2x
2 = x

We can check this by putting x = 2 in the original equation.

If it takes six men six days to dig six holes, how long will it take one man to dig half a hole?

Answers

It will take 3 days for 1 man to dig half of that complete hole.

What are direct and inverse proportion ?

Direct proportion if increase in one quantity also results in increase in another quantity for example price and weight of something.

Inverse proportion is when increase in one quantity results in decrease in another quantity for example time is inversely proportional to (speed when distance is constant.

According to the given question

6 men are working together then it takes them 6 days to dig 6 holes.

∴ Number of men days = 6 days × 6 men = 36 men days

So, in 36 men days 6 holes are dug. Now the men days and the number of holes being dug are in direct proportion with one another.

Hence number of men-days required to dig one hole

= 36/6 men days

= 6 men days

∴ No. of men days required to dig half a hole

= 6/2

= 3 men days

So, It takes 1 man 3 days to dig half a hole.

Final answer:

Using the elimination method, we solved the system of linear equations to find that the solution is x = 3 and y = 1/2.

Explanation:

The student is asking us to solve a system of linear equations. The equations given are:

3x + 2y = 10

2x + 3y = 15/2

To solve these equations, we can use either substitution or elimination method. Let's go ahead with the elimination method to find the values of x and y.

Multiply the first equation by 3 and the second equation by 2 to make the coefficients of x the same:

9x + 6y = 30 (multiplying the first equation by 3)

4x + 6y = 15 (multiplying the second equation by 2)

Now, subtract the second equation from the first equation to eliminate y:

9x + 6y - (4x + 6y) = 30 - 15

5x = 15

x = 3

Now plug x=3 into the first original equation:

3(3) + 2y = 10

9 + 2y = 10

2y = 1

y = 1/2

Therefore, the solution to the system of equations is x = 3 and y = 1/2.

K^2+kf-2f^2

The answer is correct

Answer:

Factorized form of the given expression is (k + 2f)(k - f).

Step-by-step explanation:

The given expression is k² + kf - 2f² and we have to factorize the given expression.

k² + kf - 2f² = k² + 2kf - kf - 2f²

= k(k + 2f) - f(k + 2f)

= (k + 2f)(k - f)

So the factorized form of the expression is (k + 2f)(k - f).

Answer:  The required solution in interval notation is [tex](0,\infty)U(-\infty,-5].[/tex]

Step-by-step explanation:  We are given to find the solution to the following compound inequality in interval notation :

[tex]2(x+3)>6~or~2x+3\leq -7~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

To find the solution to (i), we must solve both the parts separately.

The inequality (i) can be solved as follows :

[tex]2(x+3)>6\\\\\Rightarrow x+3>\dfrac{6}{2}\\\\\Rightarrow x+3>3\\\\\Rightarrow x>3-3\\\\\Rightarrow x>0\\\\\Rightarrow x\epsilon (0,\infty)[/tex]

or

[tex]2x+3\leq-7\\\\\Rightarrow 2x\leq-7-3\\\\\Rightarrow 2x\leq -10\\\\\Rightarrow x\leq -\dfrac{10}{2}\\\\\Rightarrow x\leq-5\\\\\Rightarrow x\epsilon(-\infty,-5].[/tex]

Thus, the required solution in interval notation is [tex](0,\infty)U(-\infty,-5].[/tex]

Expand the following using either the Binomial Theorem or Pascal’s Triangle. You must show your work for credit. (x - 5)5

Answers

well, using the binomial theorem, is far simpler, since you get the coefficient as you go and only the ones you need.

[tex]\bf (x-5)^5\implies \begin{array}{llll} term&coefficient&value\\ -----&-----&-----\\ 1&+1&(x)^5(-5)^0\\ 2&+5&(x)^4(-5)^1\\ 3&+10&(x)^3(-5)^2\\ 4&+10&(x)^2(-5)^3\\ 5&+5&(x)^1(-5)^4\\ 6&+1&(x)^0(-5)^5 \end{array}[/tex]

notice, with the binomial theorem, you start the first element with the highest exponent, in this case 5, and the second element with 0, and then you gradually decrease it by 1 to the first one and increase it by 1 to the second one.

That part is rather simple, now, to get the coefficient, the 1st coefficient is 1 for one, to get the next one is "the product of the current coefficient and the exponent of the first element, divided by the exponent of the second element on the next term"...which is a mouthful...but anyway ... for example

how did we get 10 for the 3rd term?  5 * 4 / 2

how did we get 10 again for the 4th term though?  10 * 3 / 3

and the 5th coefficient?    10 * 2 / 4

A person 6 ft tall casts a shadow 5​ft long. at the same​ time, a nearby tree casts a shadow 31 ft long. find the height of the tree

Answers

Therefore, the tree's height is 37.2 feet.

We can use proportions to find the height of the tree based on the shadow it casts and compare it to the height and shadow of a known object (in this case, a person). Given that a person 6 ft tall casts a 5 ft long shadow, we can set up a proportion with the tree's 31 ft long shadow to find its height. The formula we use for this comparison is:

Person's Height / Person's Shadow = Tree's Height / Tree's Shadow

Plugging in the numbers:

6 ft / 5 ft = Tree's Height / 31 ft

Now, we solve for the Tree's Height:

6 ft * (31 ft / 5 ft) = Tree's Height

Tree's Height = 37.2 ft

Therefore, the height of the tree is 37.2 feet.

Mr. Plum's math class of 25 students had an average of 85 on a test. Miss Scarlett's class of 22 students had an average of 87 on the same test. What is the average of the two classes combined?

Answers

Add the two averages together and then divide it by 2. Thats your answer.

A mean is an arithmetic average of a set of observations. The average of the two classes combined is 85.936.

What is Mean?

A mean is an arithmetic average of a set of observations. it is given by the formula,

Mean = (Sum of observations)/Number of observations

Mr. Plum's math class of 25 students had an average of 85 on a test.

Average = Total marks /Total number of students

Total marks of Mr. Plum's class = Total number of students × Average

Total marks of Mr. Plum's class = 25 × 85

Total marks of Mr. Plum's class = 2,125

Miss Scarlett's class of 22 students had an average of 87 on a test.

Average = Total marks /Total number of students

Total marks of Miss Scarlett's class = Total number of students × Average

Total marks of Miss Scarlett's class = 22 × 87

Total marks of Miss Scarlett's class = 1,914

Further, the average of the two classes combined is,

Average = Total marks / Total students

              = (2,125 + 1914)/(25+22)

              = 4039/47

              = 85.936

Hence, the average of the two classes combined is 85.936.
