You just told us that 't' is the tax, and 'c' is the cost of the item.
We know it's not the 'equals' sign (=), so the only thing left
that it could be is the 0.07 .
you cannot show too much "work"
basically, you remove what is common to all of the factors, and then put brackets, as it will be multiplied back in, remember that when you multiply exponents with the same base, its same as adding them, so subtract to remove...
you can seperate two of the variables , then factor, then subtract the last one from those two, because it cannot be factored out , as in part2 #2
This is a simple division problem
301/7= 43 mph
12 = 4*3 = 2*2*3
8 = 4*2 =2*2*2
greatest common factor = 2*2 =4
they can have 4 teams: consisting of 3 boys and 2 girls
Assuming the first function is y = 4x2<span> + 1, and the second y = 4x</span>2<span> then the first graph is 1 unit higher than the second.</span>
