Part 1

its asking you to find the slope of the given lines by using the points that they have plotted on the lines

first you need to figure out what the points are, then insert it into the formula

the formula for this would be [tex]\frac{Y2- Y1}{X2-X1}[/tex]

Part 2:

its asking you to find the slope using the points that are written in each box

again, just substitute it into the formula

the formula for this would be [tex]\frac{Y2- Y1}{X2-X1}[/tex]

Boyle’s law states that when considering gases, volume varies inversely with pressure. If V represents the volume of the gas and P represents the pressure of the gas, what would the formula be that represents this relationship? If a balloon has a volume of 4 L of gas with a pressure of 5 atmospheres, what will the volume be when the pressure is 3 atmospheres?


The formula is V = kP, and when P = 3, V = 4/3

The formula is V = kP, and when P = 3, V = 5/3

The formula is k = VP , and when P = 3, V = 4.

The formula is k = VP, and when P = 3, V = 20/3

Answers

Answer:

D.

[tex]V = 20/3L[/tex]

Step-by-step explanation:

Given

[tex]P = 5atm; V = 4L[/tex]

Required

Determine V when P = 3atm

Boyles Law states that;

[tex]k = VP[/tex]

When : [tex]P = 5atm; V = 4L[/tex]

[tex]k = 5 * 4[/tex]

[tex]k = 20[/tex]

Using the same formula:

[tex]k = VP[/tex]

When [tex]P = 3atm[/tex]

We have:

[tex]20 = V * 3[/tex]

Solve for V

[tex]V = 20/3L[/tex]

Answer:

What is the equation of the line that passes through the point (-9. 6) and is
perpendicular to the line -5 + x = 3y

Answers

Answer:

The perpendicular equation is y = -3x -21

Step-by-step explanation:

Perpendicular lines have the exact opposite slope as the other equation and they never have the same y-intercept.

To find the perpendicular slope just look at the slope in the original equation and get the exact opposite.

First let's simplify the equation.

-5 + x = 3y (divide by 3 on both sides to get y by itself)

-5/3 + 1/3x = y or y = 1/3x + 5/3

The exact opposite of this slope would be -3.

Now plug in the point you were given so that we can find the y-intercept.

6 = -3(-9) + b   (b = y-intercept)

6 = 27 + b (subtract 27 on both sides)

-21 = b

So the perpendicular equation looks like this.

y = -3x -21

A cable television station runs a marathon broadcasting 11 hours of program A, immediately followed by 11 hours of program B, immediatly followed by 11 hours of C. If the first episode of program A begins at 8pm. What time does the last episode of program C end?

Answers

Answer:

2 am

Step-by-step explanation:

We are told in the question that:

A cable television station runs a marathon broadcasting 11 hours of program A, immediately followed by 11 hours of program B, immediatly followed by 11 hours of C. If the first episode of program A begins at 8pm. What time does the last episode of program C end?

Program A

8pm + 11 hours = 6am

Program A ends by 6am

Program B

Starts by 6 am

6am + 11 hours = 4 pm

Program B ends by 4 pm

Program C

Starts by 4 pm

4 pm + 11 hours = 2am

Program C ends by 2 am

Answer:

[tex]End\ Time = 4am[/tex]

Step-by-step explanation:

Given

[tex]Start\ Time = 8pm[/tex]

[tex]A = 11\ hours[/tex]

[tex]B = 11\ hours[/tex]

[tex]C = 11\ hours[/tex]

Required

Determine when the last episode of C ends.

This is calculated as thus;

[tex]End\ Time = Start\ Time + A + B + C[/tex]

[tex]End\ Time = 8pm + 11\ hours + 11\ hours + 11\ hours[/tex]

[tex]End\ Time = 8pm + 33\ hours[/tex]

Split 33 hours into 24 hours + 9 hours

[tex]End\ Time = 8pm + 24\ hours + 9\ hours[/tex]

24 hours after a certain time equas the same time on a different day:

[tex]End\ Time = 8pm + 9\ hours[/tex]

9 hours after 8pm is 4am

Hence:

[tex]End\ Time = 4am[/tex]

Solve in inequality: -2 (3x + 5) ≥ 10

Answers

Answer:

x ≤ -10/3

Step-by-step explanation:

Step 1: Write inequality

-2(3x + 5) ≥ 10

Step 2: Solve for x

Distribute -2: -6x - 10 ≥ 10Add 10 to both sides: -6x ≥ 20Divide both sides by -6: x ≤ 20/-6Simplify: x ≤ -10/3

Here we see that any value less than or equal to -10/3 will work as a solution.

Answer:

x < - 3.333 repeating

Step-by-step explanation:

-2(3x + 5) >= 10

open the parenthesis

-6x - 10 >= 10

-6x - 10 + 10 >= 10 + 10

-6x > 20

-6x/-6 > 20/-6

since you divided by a negative, the sign gets flipped

x < -3.33 repeating

Add 3 to both sides

Answer with step-by-step explanation:

Add 3 to both sides

When solving equations like this, you need to make both sides as simplified as possible. In this case, x - 3 = 18, so you'd simplify the equation by adding 3 to both sides. In the end, x = 21

My 4-digit number is a palindrome (meaning, that it does not change if you write it backwards), and it has remainder 21 when you divide it by 100. What is my number?

Answers

Answer: 1221

Step-by-step explanation:

Given : A  4-digit number is a palindrome .

If it has remainder 21 when you divide it by 100, then last two digits are 21.

So required palindrome =  _ _ 21

since palindrome does not change if you write it backwards, so first two numbers should be reverse of 21 = 12

hence, the complete palindrome = 1221

So the number is 1221.
