Answer: k = 2x
Step-by-step explanation:
x2 = k
Swap sides so that all variable terms are on the left hand side.
k=x
2
I think the answer is C hope this would help you
Alright lets interpret this first.
x - 4 = 4( x + 2 )
This question is basically asking you if it has infinite, none or only one solution.
To figure out no solutions you would need to find out if x = anything.
let's simplify first!
x - 4 = 4x + 8
Now once you remove all the parenthesis you can actually take out two options.
Infinite and No Solutions.
It is not infinite because in its simplest form they are still different.
It is not no solutions because it can still be done (they aren't impossible)
Example:
No solution -> (x+2)=(x+3)
Infinite -> (x+2)=(x+2)
Now back to the problem!
x - 4 = 4x + 8
Solve for x to find out what the solution is.
Do this first by taking out the x
-4 = 3x + 8
subtract the 8
-12 = 3x
finally divide by 3
-4 = x
Tada!
Hope this helps!
Given the time t = 2 seconds, simply plug in it to the equation.
h = - 16(2)² + 541
= - 16(4) + 541
= - 64 + 541
h = 477 feet
