<span>|4x + 12| = 16
As it is in modulus function, it could be either +ve or -ve
4x+12 = 16 OR 4x - 12 = 16
4x = 16-12 OR 4x = 16 + 12
4x = 4 OR 4x = 28
x = 4/4 OR x = 28/4
x = 1 OR x = 7

In short, Your Answer would be either 1 or 7

Hope this helps!</span>

Write this equation in vertex form.<br> y = x^2 -12x +20

kotegsom [21]

Answer:

$y = (x-6) ^ 2 -16$

Step-by-step explanation:

The vertex form for a quadratic equation has the following form:

$y = (x-h) ^ 2 + k$

Where the vertice of the equation is the point (h, k)

To transform the equation $y = x ^ 2 -12x +20$ in its vertex forms we must find its vertex.

Be a quadratic equation of the form:

$ax ^ 2 + bx + c$

Where a, b and c are real numbers, then the vertex of the equation will be:

$x = - \frac{b}{2a}$

For the given equation:

$b = -12\\a = 1$

Therefore the vertice is:

$x = - \frac{-12}{2(1)}\\\\x = 6$

Now we substitute x = 6 into the equation and find the value of k.

$y = (6) ^ 2 -12 (6) +20\\\\y = -16 = k$

Therefore the vertice is: (6, -16)

And the equation is:

$y = (x-6) ^ 2 -16$

What is 3 1/8 - 1/2

irina1246 [14]

Answer:

$\frac{21}{8}$

Step-by-step explanation:

Given: $3\frac{1}{8} - \frac{1}{2}$

Let's changed that mixed number to an improper fraction. Now we get:

$\frac{25}{8} - \frac{1}{2}$

Let's find out least common denominator. This one is easy, the LCD is 8. Now that we know the LCD, let's convert both our fractions:

$\frac{25}{8} - \frac{4}{8}$

We can use $\frac{4}{8}$ because it is equal to $\frac{1}{2}$ . Now, all we need to do is subtract the numerators:

$\frac{25}{8} - \frac{4}{8}=\frac{21}{8}$
