Answer:
I can help you with 1, 2 and 3.
Step-by-step explanation:
1. 2x + 3y = 1470
Subtract 2x from both sides: 3y= -2x+1470
Divide three from both sides: y= \frac{-2}{3}x +490
2. To graph it, you would first go to (0,490) because that is where the y-intercept is. Since slope is ride over run, you can either go up 2 left3 or down 2 right 3. You can proceed doing that until you have enough points to draw the line.
3. f(x)= -2/3x +490. This function means represents how many wraps are sold based on how many rolls are sandwich.
I like to start by dividing the given number by 2, unless a larger factor is evident.
1386 = 2(693). It's pretty obvious that we can divide 693 by 3: 693=3(231).
Then we have 1386 = (2)(3)(231). Try the same procedure. Does 231 have any integer, prime factors? See how far you can take this factoring.
