First work out the parenthesis:

9x⁴y⁴ / 3y²

Then get rid of the denominator using 9/3=3 and y⁴/y² = y²

3x⁴y² is the simplest form.

Mrs William has a prized box with different colored tickets. Each ticket results in different type of prize.
Lera25 [3.4K]

\text{ Answer:} \text{ Probability that he chooses a yellow ticket and then a purple ticket }= \frac{3}{25}

Step-by-step explanation:

Since we have given that

Number of green tickets =3

Number of yellow tickets = 4

Number of purple tickets = 3

Total number of tickets = 3+4+3=10

Now,

As we know that Pedro select a ticket and replace it and then select another ticket , total number of outcomes will never change it will be 10 only for each case.

Probability that he chooses a yellow ticket and then a purple ticket is given by

\frac{4}{10}\times \frac{3}{10}\\\\=\frac{12}{100}\\\\=\frac{3}{25}

Could anybody give me some help? I'm a little confused .-. <3

What your teacher wants is for you to isolate y in the given equation. In other words, get y all by itself. 

To do this, you'll do two basic steps:
Step 1) Subtract 2x from both sides
Step 2) Divide both sides by 3

Let's do that and we get...
2x+3y = 1470
2x+3y-2x = 1470-2x ... apply step 1
3y = 1470-2x
3y = -2x+1470
3y/3 = (-2x+1470)/3 ... apply step 2 
y = (-2x)/3 + 1470/3
y = (-2/3)x + 490

After isolating y, we get y = (-2/3)x + 490
To get this into function notation, we simply replace y with f(x) to get the final answer f(x) = (-2/3)x+490 which is the same as writing f(x) = -\frac{2}{3}x+490

This graph represents all of the ordered pairs (x,y) that make the original equation true. For example, the point (x,y) = (0,490) is on the line where x = 0 and y = 490. This point is when 0 sandwiches are sold and 490 wraps are sold yielding a profit of $1470. Another point on this line is (x,y) = (3,488). Now 3 sandwiches have been sold along with 488 wraps leading to the same profit of $1470. Any ordered pair point you pick on the line should lead you to the same profit.
