50-6x=y
since each car wash is 6 dollars and you do not know the number of cars washed it is 6x
50-6x is because you need to find out how much is left in the card so you subtract the total from how much she spent
Numbers that are 510 to 540 (with zeroes) I'm not too sure about the ones place but also numbers 1-4. For example, 521, 1 rounded to 20 = 20. 20 rounded to 500 = 500. You get me?
Answer:
y>=1*x+2
Step-by-step explanation:
y>=k*x+n
we know that 2=k+n and 0=-2k+n
so 4=2k+n and 0=-2k+n
now 4=2n so n=2
now k=1
so y>=1*x+2
