Answer:
In this equation X is independent variable while Y is dependent variable.
Step-by-step explanation:
Equation:
Y=10x+100
Independent variable in math:
A variable in an equation that may have its value freely chosen without considering values of any other variable.
Dependent variable in math:
A dependent variable is a variable in an expression, equation, or function that has its value determined by the choice of value of other variable.
<u>According to above definitions Y is dependent of x. As we changes the value of x the value of Y changes.</u>
For example if x = 1, Y will be 110.
And if x = 10, Y will be 200.
Answer:
.
Step-by-step explanation:
We are given 
and 
are zeros of the polynomial 
.
We want to find the value of 
if 
.
Lets use veita's formula.
By that formula we have the following equations:
(-b/a where the quadratic is ax^2+bx+c)
(c/a)
Let's simplify those equations:
If and , then 
.
Let's solve this for k:
Subtract 6 on both sides:
Find a common denominator:
Simplify:
.
i think the answer is 1.6*10^-3
The video will end at 4.20 PM (4.50 - 30 mins). So it starts at 3.15 PM and ends at 4.20 PM. So it is 1 hour and 5 minutes.
