Answer:
All real numbers greater than or equal to 0.
Step-by-step explanation:
x must be greater or equal to zero because there is no real square root of a negative number.
So the lowest value of the function is 0 and it can be any value greater than that.
The answer is C because if you have 1 bus that’s 35 so it would be y=35(1) then if you have 2 buses it would be y=35(2) That gets you 70 seats. :)
What is the question here???
Answer:
Step-by-step explanation:
Let the number = x
Read carefully the sentence part beginning with 4 times larger
4* something
4 times larger than the square of 1/2 the number
4 * (x/2)^2
4*(x/2)^2 = x
4*x^2/4 = x
x^2 = x be very careful how you handle this. It looks like 0 might be an answer, but it isn't. If you divide x on both sides and you allow 0, you will get 0 / 0 and that is undefined. You must exclude that possibility with some sort of statement.
x cannot be 0.
x^2/x= x/x
x = 1
