We can use quadratic formula to determine the roots of the given quadratic equation.
The quadratic formula is:
b = coefficient of x term = -11
a = coefficient of squared term = 2
c = constant term = 15
Using the values, we get:
So, the correct answer to this question are option B and D
Answer:
its 48.139
Step-by-step explanation:
i also needed help , but i only saw this so i guessed the answer and it is 48.139.
Given the recursive formula, each terms is five time the previous one.
This means that:
- is 5 times , which means
- in turn, is 5 times , so we have . This means that
- Finally, So, substituting this back gives
In general, since you have , each time you compute a new term you multiply by a factor of 5, so if , you have
Answer:
(x,y) = (-2, -1)
Step-by-step explanation:
We start off by substituting the value of "x".
5x+7y=-17
x=-
We then solve 5
y=-1 *Substitute the value of "y"
x= -
x=-2
This works.
