Y = a (x + 3)² - 1

Let's take the point (-1;3)

3 = a ( -1 + 3)² - 1
3 = 4a - 1
4a = 4

Therefore a = 4/4 = 1

(x+3)² - 1
= x² + 6x + 9 - 1
= x² + 6x + 8

The answer would be y = x² + 6x + 8.

Hope this helps !

Answer:

x=3

Step-by-step explanation:

I am assuming that your equation is:

$\sqrt{8x + 12} + 4 = 10$

Subtract 4 from both sides to get:

$\sqrt{8x + 12} = 6$

Square both sides to get:

$(\sqrt{8x + 12})^{2} = {6}^{2}$

$8x + 12 =3 6$

$8x =24$

Divide both sides by 8 to get:

$x = \frac{24}{8} = 3$

In the two digit number x,both the sum and the difference of its digit is 6. What is the value of x ?

Levart [38]

Let $a$ be the first digit and $b$ the second. Then the number is $x=10a+b$ . The sum and difference of the two digits is 6, which means

$\begin{cases}a+b=6\\a-b=6\end{cases}\implies a=6,b=0$

which means the number is $x=6\times10+0=60$
