So if you want to have a factored form...

If the zeroes are +4 and +8, you would write
(X-4) (x-8)
Then you would multiply it out to get to quadratic form...

So, (x-4)*(x-8)
X^2 - 12x + 32

Then you would plug it into the formula for axis of symmetry...
X= -b/2a

X=12/2 = 6


X=6

Annette [7]

Answer:

If x=6 and y=5 and we are to find y when x=3.

it will be 6=5,3=y....

5×3=6×y.

y=15/6=2.5 or 2 whole number 1/2.

This is the answer I hope it helps

HELP !! ASAP !!
Sedaia [141]

Answer:

The roots are;

x = (2 + i)/5 or (2-i)/5

where the term i is the complex number representing the square root of -1

Step-by-step explanation:

Here, we want to use the completing the square method to solve the quadratic equation;

f(x) = -5x^2 + 4x -1

Set the function to zero

0 = -5x^2 + 4x - 1

So;

-5x^2 + 4x = 1

divide through by the coefficient of x which is -5

x^2 - 4/5x = -1/5

We now take half of the coefficient of x and square it

= -2/5^2 = 4/25

add it to both sides

x^2 - 4x/5 + 4/25= -1/5 + 4/25

(x- 2/5)^2 = -1/5 + 4/25

(x - 2/5)^2 = -1/25

Take the square root of both sides

x - 2/5 = √( -1/25

x - 2/5 = +i/5 or -i/5

x = 2/5 + i/5 or 2/5 - i/5

What is the product of 7/8×1/2
Gelneren [198K]

\frac{7}{8}   \times  \frac{1}{2}

=  \frac{7 \times 4}{8}

=  \frac{28}{8}

=  \frac{ \cancel{28}}{ \cancel{8}}

= \frac{14}{4}

=  \frac{ \cancel{14}}{ \cancel{4}}  =  \frac{7}{2}

<h2>The required answer is 7/2 </h2>
