This table displays the amount of water in a bathtub as it is being drained.

A 2-column table with 4 rows. Column 1 is labeled Time (minutes) with entries 7, 8, 9, 10. Column 2 is labeled Water (gallons) with entries 38.5, 36.25, 34, 31.75.

Use the table to interpret the rate of change.

What is the rate of change for the relationship?

Answers

Answer:

i know its late but its -2.25 if you still need it

Step-by-step explanation:

just did it on edge

The rate of change for the relationship, given the data, is -2.25 gallon/min

What is velocity?

Velocity is simply defined as the rate of change of displacement with time. Mathematically, it can be expressed as:

Velocity = displacement / time

With the above idea in mind, we can obtain the rate of change for the given relationship.

How do determine the rate of change?

Column 1 i.e time (min) = 7, 8, 9, 10.

Column 2 i.e Water (gallons) = 38.5, 36.25, 34, 31.75.

What is the formula for the Rate of change?

Rate = Change in gallon/change in time

Rate = (36.25 - 38.5) / (8 -7)

Rate = -2.25 / 1

Rate of change = -2.25 gallon/min

What is x and the measurements?

Answers

Answer:

see explanation

Step-by-step explanation:

The perimeter is the sum of the measures of the 3 sides.

Sum the sides and equate to 75, that is

2x - 9 + 3x + 4 + 2x + 3 = 75, that is

7x - 2 = 75 ( add 2 to both sides )

7x = 77 ( divide both sides by 7 )

x = 11

Thus

AB = 2x - 9 = 2(11) - 9 = 22 - 9 = 13 m

BC = 3x + 4 = 3(11) + 4 = 33 + 4 = 37 m

AC = 2x + 3 = 2(11) + 3 = 22 + 3 = 25 m

Answer:

x=11

Side lengths:

AB=13

AC=25

BC=37

Step-by-step explanation:

We can create an equation based off of the given information. Then, we simplify the equation to solve.

[tex](2x+3)+(3x+4)+(2x-9)=75\\(2x+3x)+(3+4)+(2x-9)=75\\(5x+7)+(2x-9)=75\\(5x+2x)+(7-9)=75\\7x-2=75\\7x=77\\x=11[/tex]

Then, we insert 11 for x, and evaluate the expressions for the side lengths.

[tex]AB=2x-9=2*11-9=22-9=13[/tex]

[tex]AC=2x+3=2*11+3=22+3=25[/tex]

[tex]BC=3x+4=3*11+4=33+4=37[/tex]

Finally, we check.

13+25+37 is 75, so this should be correct.

Answer:

x = 3.

Step-by-step explanation:

log4 (3x - 1) = log4 (x + 5)  Since they are both logs to the base 4:

3x - 1 = x + 5

2x = 6

x = 3.

On solving the logarithmic equation, we find that x = 3.

Answers

Answer:

y = 2x + 10

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - [tex]\frac{1}{2}[/tex] x + 7 ← is in slope- intercept form

with slope m = - [tex]\frac{1}{2}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{1}{2} }[/tex] = 2 , thus

y = 2x + c ← is the partial equation

To find c substitute (- 2, 6) into the partial equation

6 = - 4 + c ⇒ c = 6 + 4 = 10

y = 2x + 10 ← equation of perpendicular line

solve for y and find solution

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

Finding the y-intercept:

Look where the line touches the y-axis then that point is the y-intercept....in this case it's -3

Finding the Slope:

Look for a perfect point on the line then count how many places down you have to go and how many places right you have to go till you reach the next perfect point, this is called rise over run....so in this case it will go down 2 and right 1. So basically it's like this...

[tex]\frac{-2}{1}[/tex]

So that will simplify to -2

Finding the answer:

Once we plug everything in this formula...

Witch expression is equivalent to 1/5(150x - 80y + 50 - 50x- 25y + 20)?

Answers

Answer:

20x - 21y + 14

Step-by-step explanation:

1/5(150x - 80y + 50 - 50x- 25y + 20)

Step 1 - Distribute

1/5 • 150x = 30x

1/5 • (-80y) = -16y

1/5 • 50 = 10

1/5 • (-50x) = -10x

1/5 • (-25y) = -5y

1/5 • 20 = 4

Step 2 - Combine Variables

30x - 10x = 20x

-16y - 5y = -21y

10 + 4 = 14

Step 3 - Arrange the Set of Numbers

20x - 21y + 14

This is the simplified expression, I know it is correct, I doubled checked on my expression calculator.
