If 'x' apples cost 'b' cents, then each apple costs (b/x) cents.
'Y' apples cost 'y' times the cost of each one . . . . . (y) times (b/x) or <em>yb/x cents</em>.
65.0798 rounded to the nearest tenth is 65.1, if the number after the number you are rounding is 5 or over you will round up. If the number after it is under 5 then it will stay the same.
This is a linear polynomials(or first degree polynomials). It is a form of y=ax+b.The line passes through (4, 5) and (2, 2), so we can build a dualistic equation: ｛5=4k + b
｛2=2k + b
solve this equation, we can know that k=1.5 and b=-1, then the function is y=1.5x - 1, D is correct.
If y=1.5x - 1, then y-2=1.5x-1-2=1.5x-3=1.5(x-2), so A is correct, too.
y-4=1.5x-1-4=1.5x-5, so B is incorrect.
y-5=1.5x-1-5=1.5x-6=1.5(x-4), so C is correct. Now we can know the answer: the correct options are A,C and D Sorry my English expression is not very good, but hope it can help you:)
Answer:
c) 392
Step-by-step explanation:
<span>common difference for the sequence = 1/16
cause
1/4 = 4/16
and
3/8 = 6/16
so
4/16 + 1/16 = 5/16
5/16 + 1/16 = 6/16
