Answer:
no solution
Step-by-step explanation:
The discriminant is ...
b^2 -4ac = (-4)^2 -4(2)(16) = 16 -128 = -112
A negative discriminant means there are no real solutions to the equation.
_____
The complex solutions are 1±i√7.
If we assume the equation has a typographical error and is intended to be ...
2x^2 -4x -16 = 0
The solutions are x = -2 and x = 4.
You would have a 3 to 10 chance that the first 3 cars are in order
Answer:
Yes it will be able to make the journey in under a year.
Step-by-step explanation:
To find out how many hours it will take
and divide by 8400
So it will take the space ship 190.476 hours to make the trip.
Next, ask our self, how many hours are in a year?
To find out multiply 365 * 24 = 8760 hr
The 365 = number of day in a year. The 24 = number of hours in a day.
Knowing how many hours there are in a year and how long the trip will take tells us that the journey can be made under a year since there are 8760 hours in a year and we know we can make it there in 190.476 hr traveling at 8400 mph
Answer:
There are many lines with slopes of 2. When writing them, they simply need to be y = 2x + b, with which b can be any number.
Step-by-step explanation:
We know this because slope intercept form is y = mx + b, in which m is the slope of the equation.
Answer:
The needed expression is
.
Step-by-step explanation:
Here the given expression is :
"the result of multiplying 1/2 by a number, then subtracting 9"
Let us assume the given number is p.
Firstly we multiply the given number p with (1/2).

Now, subtracting 9 from the result above, we get:

So here, if the number is p, then the result is :
Hence, the needed expression is
.
