Answer:
Step-by-step explanation:
the quadratic function should be as follows:
Now let's confirm that the zeros of the function are 0 and 8
Therefore we can see that if x = 0
the equation is fulfilled
And we also have 
for this expresion to be equal to zero:
thus, if x = 8
the equation is also fulfilled
The zeros of the quadratic function are 0 and 8.
Answer:
B
Step-by-step explanation:
To solve for x, we have to get x by itself. To do this, perform the opposite of what is being done to the equation.
5x+14=k
First, subtract 14 from both sides, because 14 is being added on to 5x. Subtraction is the opposite of addition.
5x+14-14=k-14
5x=k-14
Now, divide both sides by 5, because 5 and x are being multiplied. Division is the opposite of multiplication.
5x/5=k-14/5
x=k-14/5
So, the correct answer is choice B
