Answer:
Domain: [-8. 4]
General Formulas and Concepts:
<u>Algebra</u><em><u> </u></em><u>I</u>
- Domain is the set of x-values that can be inputted into function f(x)
- Interval Notation
Step-by-step explanation:
From the graph, we can see that our x-values span from -8 to 4. Since both are closed dot, they are inclusive in the domain:
[-8. 4] or -8 ≤ x ≤ 4
Answer:
1/2
Step-by-step explanation:
Answer:
1) The value of 
is 12.
2) The length of the diagonal is 49.
Step-by-step explanation:
1) If the glass is a rectangle, then both diagonal must have the same length, that is, the following equation must be solved:
(1)
We need some algebraic handling to determine the value of :
![[5+(-2)] \cdot x = 36](https://tex.z-dn.net/?f=%5B5%2B%28-2%29%5D%20%5Ccdot%20x%20%3D%2036)
The value of is 12.
2) If we know that , then the length of the diagonal (
) is:
The length of the diagonal is 49.
Answer:
put x=1/2, you will get, r(1/2)=20*1/2-89
=10-89= -70.
hope it will help.
- h - 17 = 19 + h
-2h = 36
h = -18
Hope this helps!!
