<span>I think when you ask me to describe the end behavior of f(x)=10x^4 you mean for me to answer like this 10^4=10,000.</span>
Here is how you would work it out step by step.
You have to factor the equation you're given. (To check you factorization you can "FOIL" it and make sure it matches the original equation)
Then set the two answers you get from FOILing to zero and you should get your answers.
We have to apply the rule of three
8 servings--------------------1/2 cup of sugar
26 servings--------------------- x
x=(26 servings*(1/2) cup of sugar) / 26 servings=1.625 cup of sugar.
3/10 of the households did not use a computer.
Hope this helps.
664=60% off of original
percent means parts out of 100
60%=60/100=0.6
664=60% of original
'of' means multiply
translate
664=0.6 times originail
divide boh sides by 0.6
1106.666666=original
about $1106.67=original
or you could do ratio and proportion
664/60=x/100
answer is still $1106.67
