What are the zeros of the quadratic function f(x)=8^2-16-15
Free_Kalibri [48]

Answer:

C)

Step-by-step explanation:

f(x)=8x^{2} -16x-15
8x^{2} -16x-15=0
x=\frac{-b+-\sqrt{b^{2}-4ac } }{2a}  ,  a=8, b= - 16, c= - 15

x=\frac{-(-16)+-\sqrt{(-16)^2-4*8*(-15)} }{2*8} = \frac{16+-\sqrt{736} }{16} =\frac{16+-4\sqrt{46} }{16} = 1 +- \frac{\sqrt{46} }{4} = 1+- \frac{\sqrt{23} \sqrt{2}}{2\sqrt{2} \sqrt{2} } =1+-\frac{\sqrt{23} }{2\sqrt{2} } = 1+-\frac{\sqrt{23} }{\sqrt{8} }

X+ k = w + v for x ? Some one please explain this for me
Troyanec [42]

Answer:

x = w + v - k

Step-by-step explanation:

For this question, we would have to solve for the variable x.

Solve for x:

x + k = w + v

To solve it, we would have to get "x" by itself.

Subtract k from both sides.

x = w + v - k

Since "x" is by itself, we know what the value of "x" is.

Therefore, your answer is x = w + v - k
