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

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.

Hello! Remember you have to write complete questions in order to get good and exact answers. I'll help you to understand this problem, but I have to assume some things.
We know that the empty cup in the shape of a cylinder is being filled with water. Suppose the volume of this cylinder is:

Suppose that the cup is filled at a constant rate of
, so in 7 seconds the cup is filled the following amount:

So this represents the following percentage:

Finally, after 7 seconds the cup is 77.78% filled
Answer:
2. x2 - 2x - 8 - 3/x + 3
3. 2x2 + 5x +3
4. 2x2 + 3x + 1
5. x + 7 + 8/x + 2
6. 3x + 5 - 6/3x +5
Step-by-step explanation:
Answer:
-5^x + 3x + 2
Step-by-step explanation:
(f - g)(x) = ƒ(x) -g(x) = -5^x -(-3x -2) = -5^x + 3x + 2
The absolute value of 14 is 14.l
Hope it helps :)
