How many pencils can you buy for $10 if 4x+4 pencils is 2y d  TOPIC_SOLVED

Henry could buy 4x+4 pencils for 2y dollars. How many pencils could he buy for $10? I tried to solve it with a graph. The x axis was pencils and the y axis was dollars. My slope/y-intercept equation was y=2x+2 which gave me 4 pencils for $10. Or I could have just substituted 10 for y in the original...

Okay, I figured it out with ratios and got the answer in the book, but if anyone can tell me why graphing didn't work I would appreciate it. Thanks in advance!

Re:  TOPIC_SOLVED

Until they give you some sort of relationship between x and y, I'm not seeing how you're supposed to proceed. :confused: I mean, sure, 2y = 10 so y = 5. But so what? Are you supposed to just guess that 2y must also equal 4x + 4...? I guess you are supposed to disregard the relationship, because the...

function problem: If f(x)=x(x+3), find (f(x+h)-f(x-h))/2h  TOPIC_SOLVED

If f(x)=x(x+3), find (f(x+h)-f(x-h))/2h

I'm not sure how to set it up. I tried plugging x(x+3) in for the x's in the numerator and the answer comes out wrong.

Re: 4^(2X)=10: solve for value of X in exponent  TOPIC_SOLVED

Use a log base 10. :lol:

Here are the steps. :idea:

4^2x=10
2x log^10 4=10
2x=10/log 4
x=(10/ log 4) /2

:shock: But I am 12, so I could be wrong

I still don't get it??? I don't understand why you plug x+h and x-h in. shoudn't you plug in x(x+3)? More help would be appreciated
