<h3>Answer: \sf 3\dfrac{4}{31} \quad or \quad \dfrac{97}{31}</h3>

-------------------------------------------------------------------------------------------------------

The given expression:

\sf \dfrac{2b + 3c^2}{4a^2 - 2b}

Here given <u>a = 8</u>, <u>b = 4</u>, and <u>c = 16</u>

<u />

Inserting this values

\sf \dfrac{2(4) + 3(16)^2}{4(8)^2 - 2(4)}

Simplify following

\sf \dfrac{8 + 3(256)}{4(64) - 8}

Distribute inside parenthesis

\sf \dfrac{8 + 768}{256 - 8}

Add/Subtract similar terms

\sf \dfrac{776}{248}

Simplify following, in improper fraction

\sf \dfrac{97}{31}

In mixed fraction, answer:

2+(5+y) I need help pls! If you know the answer to this problem, please explain, THANK YOU!!!
anzhelika [568]

Answer:

y= -7

Step-by-step explanation:

I'm not sure if this is what you are looking for but here you go!

If the equation is set equal to zero.

2+(5+y)=0          This is the original expression, we need to find the value for y.

5+y= -2              We move the two to the right to remove it from the left side of                    

                          the equation.

y= -7                   We repeat the same thing as we did in the last step, except              

                          with the value 5. This then gives us our y-value, which is -7.

I hope this helps!

Use the discriminant to determine all values of k which would result in the graph of
Shalnov [3]

Answer:

k > 100

Step-by-step explanation:

y= x²+20x+k

if the graph doesn't intersect the x-axis it means it has no real roots so the discriminat has to be negative so will have imaginary roots

discriminant is

b²-4ac = 20²-4*1*k = 400-4k for this to be negative k has to be more then 100 so will have 400 - a number bigger then 400

k > 100 is the solution
