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 1

Answer:

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

Step-by-step explanation:

just did it on edge

Answer 2

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

Solve for x.
10x + 44
8x - 23

Answers

Answer:

Simplifying

10x + 44 = 8X + -23

Reorder the terms:

44 + 10x = 8X + -23

Reorder the terms:

44 + 10x = -23 + 8X

Solving

44 + 10x = -23 + 8X

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-44' to each side of the equation.

44 + -44 + 10x = -23 + -44 + 8X

Combine like terms: 44 + -44 = 0

0 + 10x = -23 + -44 + 8X

10x = -23 + -44 + 8X

Combine like terms: -23 + -44 = -67

10x = -67 + 8X

Divide each side by '10'.

x = -6.7 + 0.8X

Simplifying

x = -6.7 + 0.8XStep-by-step explanation:

Rachel is saving money to buy an outfit for a party she has already saved $17 she is earning $5 each month for being a mother's helper to the family next door how many weeks until she has in 39 points $50 to buy the outfit from the store consider she is only paid for working a full week not a 1/2 week.

Answers

Answer:

18 weeks

Step-by-step explanation:

Let the number of months she worked since she is paid monthly be represented by x

The Equation to solve this question is given as:

$17 + 5 × x = $39.50

17 + 5x = 39.50

5x = 39.50 - 17

5x = 22.50

x = 22.50/5

x = 4.5 months

We are asked to calculate how many weeks.

Hence we convert the number of months to weeks

1 month = 4 weeks

4.5 months = x

4.5 × 4 = 18 weeks

Therefore, she works for 18 weeks

Answer: I got 5.0 weeks. and i got it right. it says she got paid for a FULL week, not half a week. if she got paid half it would be 4.5, but in this problem it’s focused on whole so it’s 5.0 weeks. hope this helped!

Solve the following system for all solutions:

(x - 1)^2 + (y + 3)^2 = 13

x + y = -3

Answers

Answer:

( -4, -1 ) and ( -9, - 6)

Step-by-step explanation:

Given(x - 1)^2 + (y + 3)^2 = 13 x + y = -3Solution

From the second equation we get

x = - y - 3

Substituting x in the first equation

(- y - 3 - 1)^2 + (y + 3)^2 = 13(-y - 4)^2 + (y + 3)^2 = 13(y+4)^2 + (y+3)^2 = 13y^2 + 8y + 16 + y^2 + 6y + 9 = 132y^2 + 14y + 12 = 0y^2 +7y +6 = 0(y+1)(y+6) = 0y = - 1y = - 6

Answer: (2, 9 )

========================================================

Explanation:

Any point is of the form (x,y). The x coordinate is always listed first.

We're given (2, ___) where the y value is missing in the blank.

So we're given x = 2.

Plug this into the given equation to find y

y = 2x+5

y = 2*2+5 ... replace x with 2

y = 4+5

y = 9

Therefore (2, ___) updates to (2, 9 )

Suzy's Sculpting gym charges a $10 application fee and $12 per month for membership. Tami's Toning does not charge an application fee, but charges $14 per month for membership. After how many months will the total cost of membership be the same for both gyms?

Answers

Answer:

Total cost of membership will be the same for both gyms after 5 months.

Step-by-step explanation:

Given: Suzy's Sculpting gym charges a $10 application fee and $12 per month for membership.

Tami's Toning does not charge an application fee, but charges $14 per month for membership.

To find: After how many months will the total cost of membership be the same for both gyms

Solution:

Let [tex]t[/tex] denotes number of months after which total cost of membership will be the same for both gyms

For Suzy's Sculpting gym,

Total charges [tex]= 10+12t[/tex]

For Tami's Toning,

Total charges [tex]=14t[/tex]

Now solve [tex]10+12t=14t[/tex]

[tex]10+12t=14t\\10=14t-12t\\10=2t\\t=\frac{10}{2}\\ t=5[/tex]

So, total cost of membership will be the same for both gyms after 5 months.
