Answer: i think its 9 but sorry if I'm wrong I'm only in 4th grade
Step-by-step explanation:
The common difference is 5 each time. Take for example -9 and -4 it’s goes up 5, and then 1 and 6 it goes up five and so on,hope this helped!
380-57= 323
Answer: 323 legos remain
Range of is [4,∞).
<u>Step-by-step explanation:</u>
Here we have , function , We need to find range of this function . Let's find out:
In the function , Let's focus on : It's a perfect square whose value will be always positive and greater then equal to zero i.e.
⇒ , So minimum value of is 0 at x=-3 . ∴
⇒
⇒
⇒
Minimum value of is 4 , And maximum value of can be ∞ as value of x can be increased . Therefore , Range of is [4,∞).
When you write a polynomial in the form
You know that you have a polynomial of degree , which crosses the x axis at
So, in your case, you have a cubic which crosses the x axis at x=-5, x=-1 and x=2.
Moreover, since A=1/2 is positive, the end behaviour of the cubic is preserved, i.e.
This is all the information you need to sketch a first draft of the graph.
