Answer:
x² - (4 ≤ 5)
Step-by-step explanation:
(I have x representing the number that is squared, it might be a different letter on your options, but regardless it will be the same general answer. You also may not need the parentheses around the 4 ≤ 5)
Difference means subtraction so we know that the second number/group of numbers will be subtracted from the first that is listed.
Next, if you are squaring any number it's going to have the little 2 to the right of it. That's what that means.
Then, we look at that last bit. <em>"Four is less than or equal to five."</em> This means exactly how it sounds. To write this we need the symbol ≤. This symbol means less than or equal to. You would would but the 4 in front and the 5 in back to get 4 ≤ 5.
Now we just put it together. It tells us that 4 ≤ 5 is being subtracted from a number squared. So this means that a number squared needs to be first, and because difference means subtraction, we would subtract 4 ≤ 5 from that. A number squared can be represented by any letter variable, but for this example, I will use x.
This leaves you with x² - (4 ≤ 5)
I hope this helped :)
Answer:
Step-by-step explanation:
you just give 2 a common factor
2(-5x+1)
An example of quadratic equation with this behavior is:
Which is sketched at the end of this answer.
A quadratic equation has the format:
It's roots are given by:
The number of roots depends on the discriminant 
, that is:
- If
, it has two different real roots. - If
, it has one real root. - If
, it has no real roots.
In this problem, it will have only positive y-values if: and 
Thus, an example is:
Which is sketched below.

Answer:
Step-by-step explanation:
when you look at the graph.. and move to where x =0.. the line of the graph is going thur -5.... so that's what they are asking.. what number is the line at when x=0.... it's -5...
