To find out how many 3 course meals there are you will multiply all three numbers together. The reason for this is that you can group each item with each of the other options. This is a triple grouping.
4 x 4 x 5 = 80
There are 80 possible combinations.
Answer:
graph these
y = 2x + 2
y = 2x - 3
Step-by-step explanation:
2x - y = -2
2x - y = 3
convert to y intercept form
first
2x - y = -2
-y = -2x - 2
y = 2x + 2
second
2x - y = 3
-y = -2x + 3
y = 2x - 3
you are left with
y = 2x + 2
y = 2x - 3
i cannot graph these for you, but i assume you know how, there is no solution because the lines are parallel
Answer:
3x + 4y = 16 The rule is you can do any valid operation on both sides of an equation and it will still be equal. Subtract 4y.
3x = -4y + 16 Divide by 3.
x = -4y/3 + 16/3 Answer B.
I could be wrong but I got 28. I devided 420 by 15
