Multiplying both sides of this equation by 3, to eliminate the fraction, we get:

9 + m = 6.

Next, we subtract 9 from both sides to isolate m:  m = 6 - 9 = -3

Then m = -3.

Check:  Subst. -3 for m in this equation:

9 - 3       6

------- = ------ = 2 (as expected).  Thus, m = -3 is correct.

  3          3



Problem #10:

4n - 9 = -9     Add 9 to both sides:  4n = -9 + 9 = 0.

Divide both sides by 4:  n = 0.

Check:  Substitute 0 for n:  4(0) - 9 = -9  is true.

A deck of 40 cards contains 20 blue and 20 red cards. Each color has cards numbered 1 to 20.
Marina CMI [18]

Answer:

A red 5 is chosen from the deck. The card is put back into the deck and the a red card is chosen.

Step-by-step explanation:

An independent event is one whose outcome is not dependent on any other event. There are two types of cards in the deck. If a red card is selected it will be from the series 1 - 20, if the card is put back into deck and then again a red card is selected it will be again from the series 1 - 20. This is an independent event since its outcome is same irrespective of the events.

Only the Fahrenheit one plz
makkiz [27]
The formula given is:
F = 1.8C + 32
The temperature C is given as -20
So, all you have to do is plug the given C temperature in the formula to get the corresponding F temperature as follows:
F = 1.8(-20) + 32 = -36 + 32 = -4 degrees Fahrenheit

Drag each tile to the correct location on the image. Each tile can be used more than once, but not all images will be used.
OverLord2011 [107]

Answer:

Switch x and y, and solve for y

f^{-1}(x) =\frac{(x -4)^3}{8}

Step-by-step explanation:

Given

f(x) = 3\sqrt{8x} + 4

Required

Complete the steps to determine the inverse function

Solving (a): Complete the blanks

Switch x and y, and solve for y

Solving (b): Determine the inverse function

f(x) = \sqrt[3]{8x} + 4

Replace f(x) with y

y = \sqrt[3]{8x} + 4

Switch x and y

x = \sqrt[3]{8y} + 4

<u>Now, we solve for y</u>

Subtract 4 from both sides

x -4= \sqrt[3]{8y} + 4-4

x -4= \sqrt[3]{8y}

Take cube roots of both sides

(x -4)^3= 8y

Divide both sides by 8

\frac{(x -4)^3}{8} = y

So, we have:

y =\frac{(x -4)^3}{8}

Hence, the inverse function is:

f^{-1}(x) =\frac{(x -4)^3}{8}

Jan is trying to increase her water intake to meet recommended guidelines. She currently consumes 2 (24 oz. each) bottles of wat
castortr0y [4]

Answer:

Extra 4 cups to make up 11 cups a day

Step-by-step explanation:

Here we have that Jan obtains 15% of her fluid needs from food, therefore, she gets the remaining 85 % from drinking water

If the recommended daily intake = 2.7 liters  or 91.3 oz

And she already consumes 48 oz of water and  16 oz of milk

Note milk is equivalent to 0.87 water therefore total intake = 48 + 16*0.87= 61.92 oz

She needs to take additional (91.3 - 61.92) = 29.4 oz or 3.68 ≈ 4 cups extra to meet her recommended daily dosage.
