Answer:
y = 2/3x
Step-by-step explanation:
3x + 2y = 6
2y = 6 - 3x
y = 3 - 3x/2 or y = - 3/2x + 3
- - - - - - - - - - - - - -
Then find the negative reciprocal of the slope of the original line.
y = 2/3x
Answer:
It is found when the line starts moving up or down.
Step-by-step explanation:
1. There
are 10, 000 combinations, you have 10 choices for the four digit and there are
10 x 10 x 10 x 10 which is 4-digit combination from 1-9. This is called combinations;
the calculation comes out to 10^4.
You plug the x value into whichever function it applies to. X represents the number of shirts ordered. So for example, the first question asks the total cost if you order 57 shirts. Look at the piecewise function. If says is x>50 (or equal), you use the equation 14x + 20. 57 is greater than 50 so plug it into the equation. (14)(57) + 20 = 818. You should be able to do the rest now. If you have any more questions, you can ask.
