Answer the following linear equations: x3+y3+z3=k
2x – y = 6, x – y = 2
and ax + by = a-b, bx – ay = a+b
TYVM!! :)

Answers

Answer 1

Answer:

Linear Equation 1 — 3xyz

Linear Equation 2 — x = 4 and y = 2

Linear Equation 3 — x = 1 and y = (-1)

Step-by-step explanation:

(Linear Equation 1)
The equation x3+y3+z3=k is known as the sum of cubes problem. While seemingly straightforward, the equation becomes exponentially difficult to solve when framed as a "Diophantine equation" -- a problem that stipulates that, for any value of k, the values for x, y, and z must each be whole numbers.

The required result must be 3xyz.
(Linear Equation 2)

2x − y = 6   ....(1)

x − y = 2  ....(2)

Equation(2)−Equation(1) we get

x − y − 2x + by = 2 − 6

(−x) = (−4)

x = 4

Substitute x = 4 in (1) we get

2x − y = 6

2*4 − y = 6

8 − y = 6

(−y) = 6 − 8

y=2

(Linear Equation 3)

ax + by = a − b .......... (1)

bx − ay = a + b .......... (2)

Multiply equation (1) with a  and  equation (2) with b ,

a²x + aby = a² − ab ..........(3)

b²x − aby = ab + b² ......... (4)

Adding (3) and (4), we get,

(a² + b²)x = a² + b²

x = 1

Now, from (1),

ax + by = a − b

a + by = a − b

by = (−b)

y = (−1)


Hope my answer helps you ✌️

Answer:

5)= U(-3,0), M(-1,4), L(-2,0)

6)= R(-4,2), D(-4,5), L(0,2)

Step-by-step explanation:

The x shouldn't change. If this isn't correct, I apologize. But I'm sure I calculated this right.

The coordinates of the figure after a translation of 5 units up is U' ( -3 , 1 ) , M' ( -1 , 4 ) and L' ( -2 , 0 )

The coordinates of the figure after a translation of 3 units up is R' ( -4 , 0 ) , D' ( -4 , 4 ) , L' ( 0 , 3 ) and F' ( 0 , 0 )

What is Translation?

A translation moves a shape up, down, or from side to side, but it has no effect on its appearance. A transformation is an example of translation. A transformation is a method of changing a shape's size or position. Every point in the shape is translated in the same direction by the same amount.

A translation in the coordinate plane moves every point on a figure a given distance in a given direction. The position of any point (x, y) on the figure changes to (x + a, y + b), where a and b are real numbers.

Given data ,

Let the translated figure be represented as A

Now , the coordinates of the figure are

a)

The coordinates of the figure are U ( -3 , -4 ) , M ( -1 , -1 ) and L ( -2 , -5 )

And , when the translation is up , the y coordinate increases by d units

The coordinates of the figure after a translation of 5 units up is U' ( -3 , 1 ) , M' ( -1 , 4 ) and L' ( -2 , 0 )

b)

The coordinates of the figure are R ( -4 , -3 ) , D ( -4 , 0 ) and L ( 0 , 0 ) and F ( 0 , -3 )

And , when the translation is up , the y coordinate increases by d units

The coordinates of the figure after a translation of 3 units up is R' ( -4 , 0 ) , D' ( -4 , 3 ) , L' ( 0 , 3 ) and F' ( 0 , 0 )

Hence , the translation is solved

To compare the measures of center of two data sets as a multiple of their measures of variation, their measures of variation must be similar. Why do you think this is true?

Answers

To compare two data sets, their variation must be similar because the variation will affect many other variables, including the mean.

What is the variation?

When referring to data, the variation is about how much the data variates or the range of the data. For example, if you ask people about their age, the data can spread from 10 years old to 90 years old.

Why is variation important?

This affects other variables when analyzing data such as the mean, which implies you can only compare two sets of data if the variation is similar.

The average grain of salt is 0. 0003 meters wide. Rhinovirus, which causes the common cold, is 0. 00000003 meters wide. How many times wider is a grain of salt than Rhinovirus? Choose the correct answer. A. 1 × 102 times B. 1 × 103 times C. 1 × 104 times D. 1 × 105 times

Answers

Number of times a grain of salt is wider than Rhinovirus

= width of average grain of salt / width of rhinovirus

=0.0003 / 0.00000003

=1 × 10^4

Hence, the number of times a grain of salt is wider than Rhinovirus is 10,000 times.

Does 6/10+8/100 = 14/10 or 68/10??

Answers

Answer:

The answer is 68/100 or 17/25

Step-by-step explanation:

To solve this problem, you need to find common denominators. In this equation, the easiest way to do this is to make both fractions have a denominator of 100. 8/100 is already in the proper denominator, and 6/10 can be multiplied by 10 to get 60/100. After adding, you get 68/100 which simplifies to 17/25

A spinner with repeated colors numbered from 1 to 8 is shown. Sections 1 and 8 are purple. Sections 2 and 3 are yellow. Sections 4, 5, and 6 are blue. Section 7 is red. Determine the theoretical probability of the spinner not landing on yellow, P(not yellow).

Answers

Answer: 0.75 or [tex]\frac{3}{4}[/tex]

Step-by-step explanation: Well there are 2 section colored purple, 2 sections yellow, 3 sections are blue, and 1 section is red.

First lets find the number of favorable outcomes, which would be outcomes with out yellow. 6 out of 8 sections do not have yellow therefore the amount of favorable outcomes is 6.

Now for the total amount of outcomes which is 8.

If we input those numbers in this formula [tex]\frac{Favorable Outcomes}{Total Outcomes}[/tex] so [tex]\frac{6}{8}[/tex] we get 0.75 or [tex]\frac{3}{4}[/tex].

Together, teammates Pedro and Ricky got 2685 base hits last season. Pedro had 281 more hits than Ricky. How many hits did each player​ have?

Answers

Answer:

1,483 is the answer

Answer:

Step-by-step explanation:

Let's say Pedro got x hits

and Ricky got y hits.Given,Pedro and Ricky together got 2685 hits.So, the

equation will be as (x+y)=2685................eq (1)

Given,Pedro had 281 more hits than Ricky.So the equation looks like

x=281+y..........eq(2).

substitute eq(2) in eq(1).We get,

2685=(281+y)+y

2685=281+2y

2685-281=2y

2404=2y

2404/2=y

y=1202

substitute y=1202 in eq(2).We get,

x=1202+281

x=1483

So,Pedro hit 1483 and Ricky hit 1202

A biologist is studying the growth of a particular species of algae. She writes the following equation to show the radius of the algae, f(d), in mm, after d days:

f(d) = 9(1.04)d

Part A: When the biologist concluded her study, the radius of the algae was approximately 12.81 mm. What is a reasonable domain to plot the growth function? (4 points)

Part B: What does the y-intercept of the graph of the function f(d) represent? (2 points)

Part C: What is the average rate of change of the function f(d) from d = 3 to d = 9, and what does it represent?

Answers

Answer:

Step-by-step explanation:

Part A: A reasonable domain to plot the growth function would be from 0 to a reasonable maximum number of days, such as 30 or 60, depending on the duration of the study.

Part B: The y-intercept of the graph of the function f(d) represents the initial radius of the algae when d = 0, which would be 9 mm.

Part C: To find the average rate of change of the function f(d) from d = 3 to d = 9, we can calculate the difference in the function values at these two points and divide it by the difference in the input values. The average rate of change represents the average growth rate of the algae over that time period.
