Answer:

3 minutes and 30 seconds

Step-by-step explanation:

7-5 = 2

3/2 = 1.5 gallons that empty per each minute

1.5 times 3 (minutes) = 4.5 gallons emptied

Remaining gallons to empty = 0.5

0.5 gallons to empty will take 30 seconds

I hope this helps :)

How can Kendra determine if the function is actually linear?

pashok25 [27]

Answer:

D. She can check to see if the rate of change between the first two ordered pairs is the same as the rate of change between the first and last ordered pairs.

Step-by-step explanation:

Find the rate of change between first two ordered pairs and the second two ordered pairs:

1. Points (2,4) and (3,9). Rate of change:

$\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{9-4}{3-2}=\dfrac{5}{1}=5$

2. Points (3,9) and (4,16). Rate of change:

$\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{16-9}{4-3}=\dfrac{7}{1}=7$

The rate of change for the linear function must the same for each two points on the graph of the function. In this case, the reate of change differs, so this function is not linear and correct option is D.

11 1/2 and 13 3/4 is?

Tpy6a [65]

This would depend on what you are asking for.

If you are adding the two numbers(which the word and is implying) you’re answer is 25 1/4.

You get this by finding a common denominator. In this case, that can be 4.

Turn 1/2 in to 2/4.

Next, you add 11 and 13 to get 24.

Then, you’ll add 2/4 and 3/4. You will get 1 1/4

Add 24 and 1 1/4. You have your answer of 25 1/4

i don’t know how to divide integers and i have a test tomorrow based on adding subtracting multiplication and division on intege

ryzh [129]

In order to divide integers, the first thing to check is the sign:

- When dividing two positive integers, the result will be a positive integer.

- When dividing two negative integers, the result will be a positive integer.

- When dividing integers with different signs (one negative and one positive), the result will be a negative integer.

Then, after checking the sign, we need to calculate the value of the division.

Some examples of divisions are:

$\frac{24}{8},\frac{-15}{5},\frac{-100}{-10}$

In the first division, the result is 3, because we have that 8 * 3 is equal 24.

Also, both numbers are positive, so the result is also a positive number.

In the second division, the result is -3, because 5 * (-3) is equal -15.

The result is negative, because the two numbers have different signs.

In the third division, the result is 10, because -10 * 10 is equal -100.

The result is positive, because both numbers are negative.

Solve equation for X<br> c(x-3)-4=b(x+7)

Alenkasestr [34]

Answer:

c(x-3)-4=b(x+7)
(cx-c•3)-4=b(x+7)
cx-3c-4=b(x+7)
cx-3c-4=bx+b•7
-3c-7b-4=bx-cx
x(b-c)=-3c-7b-4
x(b-c)/b-c = -3c-7b-4/b-c

x=-3c+7b+4/b-c
