If the equation x² + 16x + c = 0 has only one real solution, the value of c is equal to 64.
<h3>Discriminant: </h3>
The quadratic formula includes the discriminant, which comes after the square root. The discriminant of a quadratic equation is important because it indicates the quantity and kind of solutions.
The formula for the Discriminant of a Quadratic Equation ax²+bx +c = 0 is given by
<h3> Discriminant Δ = b² - 4ac </h3>
Here we have
x² + 16x + c = 0 equation has only one real solution
Compare given equation with ax²+ bx + c = 0
=> a = 1, and b = 16
As we know when an equation has only one real solution
then its Discriminant will be equal to zero
=> b² - 4ac = 0
By the above values,
=> 16² - 4(1)c = 0
=> 256 - 4c = 0
=> 4c = 256
=> c = 256/4
=> c = 64
Therefore,
If the equation x² + 16x + c = 0 has only one real solution, the value of c is equal to 64.

Answer:
<em><u>B, The second table.</u></em>
Step-by-step explanation:
If you rode a bike 0.1 Kilometers per minute, and you ride for 5 minutes, you would have biked <em><u>0.5 Kilometers</u></em>, not 0.1 Kilometers.

Answer:
Step-by-step explanation:
Group like terms 6y-2y= 2-1-2
When a number goes over the equal sign= positive + changes to negative, vice versa.
So final answer is 4y= -1= -4y
Because 4 is decided by -1
