Answer:
The solution to the equation are x = 5.089 and x = -0.589
Step-by-step explanation:
Given:
x(at the power of 2) = 6 + 9x
To Find:
The solution of the equation = ?
Solution:
The given equation can be written as
=> 
=>
=>
Using the quadratic formula,
where
a= 2
b = -9
c = -6
Substituting these values,
x =5.089 x = -0.589
Answer: I had to anotate it , so you have to download that file. Good luck with what you doing.
Step-by-step explanation:
Since it turns downwards (the shape on an "n", it is a maximum point)
Maximum point occurs at (-2, 1)
Answer: (B) (-2, 1) maximum
This is a simple equation.
The equation is y = 1.6x with y being the miles and x being the kilometers.
Lets plug the kilometers in.
Y=1.6(7.7)
1.6 * 7.7 = 12.32
12.32 miles is equal to 7.7 kilometers
HOWEVER
There are about .6 miles in a kilometer, so if you typed this wrong I don't know.
It is still the same concept.
Y = .6x
Y = .6(7.7)
.6 * 7.7 = 4.8
In this case there are 4.8 miles in 7.7 kilometers
