Jack and Jill are hiking on a mountain. Jack's hike is modeled by the linear equation d=0.7t+3 and Jill's hike is modeled by the linear equation d=−0.7t+3, where d is the distance, in miles, from the base of the mountain and t is the time, in hours, since the start of the hike.

a. What is Jack's rate of change?

b. For Extra Credit, explain how Jack is hiking.

Answers

Answer 1

Answer:

a. Jack's rate of change is 0.7 miles per hour

b. Jack is hiking upwards

Step-by-step explanation:

a. 0.7 is his slope (a.k.a change) 0.7 miles because that is how distance is being measured and t is the time in hours

b. since his slope is positive I am assuming that he is going upwards like (/) the line is raising

(3) Describe the complement of A

(4) Describe the union of A and B

(5) Describe the intersection of A and B

Answers

Answer:

 A', is the set of all elements in the given universal set U .

But the union of sets is an operation performed on two sets, say A and B, which results in a set that has all elements belonging either to set A and set B or both.

Find the equation of the line shown above.

Answers

Answer:

y = x + 6

Step-by-step explanation:

The equation for a line in y-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

The slope of the line shown is 1/1 (which simplifies to 1).

The y-intercept is 6.

You would write the equation as y = x + 6.

Solve 4(2x - 9) = 3x + 4

Answers

8x - 36 = 3x + 4
5x = 40
x = 8

Answer:

x = 8

Step-by-step explanation:

First, you distribute

4(2x)+4(-9)=3x+4

8x - 36 = 3x + 4

Subtract 3x from both sides

(8x - 3x) - 36 = (3x - 3x) + 4

5x - 36 = 4

Then add 36 to both sides

5x (-36 + 36) = (4 + 36)

5x = 40

Then divide 5 from both sides

x = 8

Answers

Given:

Total number of patches = 39

Total number of rows = 3

To find:

The number of patches in each row.

Solution:

We have,

Total number of patches = 39

Total number of rows = 3

We need to divide the total number of patches by total number of rows to find the number of patches in each row.

[tex]\text{Number of patches in each row}=\dfrac{39}{3}[/tex]

[tex]\text{Number of patches in each row}=13[/tex]

Therefore, the number of patches in each row is 13.

Caroline is planting flowers in her garden. She plants her first 7 flowers in 4 minutes. After 12 minutes, she has planted 21 different flowers.
Which equation represents this direct variation?

Answers

The answer is B) y= 7/4x

This is because when you graph it you would go up 7 and over 4- you just had to find the rise over run. I also just made sure it was correct on edmentum!

Caroline is planting her first 7 flowers in 4 minutes and then past 12 minutes, she plants 21 different flowers. That suggests that she is planting the flowers following the given equation  y=(7/4)x.

What is dependant variable?

The dependent variable is defined as the variable whose evaluation of the independent variable determines the quality of the dependent variable. That is, it is consistently claimed that the word variable's estimate depends on the mathematical condition's free variable.

How to solve it?

Let Caroline plant y flowers in x minutes.

By using the unitary method we can observe that

4 minutes  → 7 flowers

⇒ 1 minute → 7/4 flowers

⇒ x minutes → (7/4)x flowers

Hence, Caroline is planting y=(7/4)x flowers in x minutes. And y=(7/4)x this equation represents the variation perfectly.

NOTE: We took the number of flowers planted as y because it is a dependent variable. The number of flowers depends on the time elapsed.
