Consider the sequence of steps to solve the equation 3(x-4)+5x=9x-36

liubo4ka [24]

Answer:

Simplification of the given expression gives value of x = 24.

Step-by-step explanation:

Here, the given expression is 3(x-4)+5x=9x-36

Now, by DISTRIBUTIVE PROPERTY:

A ( B - C ) = AB - AC

Simplifying the given expression step by step ,we get:

3(x-4)+5 x = 9 x - 36 ⇒ 3(x) - 3(4) + 5x = 9x - 36

or, 3x - 12 + 5x = 9x - 36

⇒ 8x - 9x = -36 + 12

or, - x = - 24

⇒ x = 24

Hence, the the simplification of the given expression, the value of x = 24.

The line of symmetry of the parabola whose equation is y = ax^2 -4x + 3 is

alex41 [277]

Answer:

B. -1

Step-by-step explanation:

If we have a parabola whose equation is:

$y=ax^{2} +bx+c$

The line of symmetry is calculated as:

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

Now, we have the equation $y=ax^{2}-4x+3$ and the line of symmetry is $x=-2$

Where:

$b=-4\\c=3$

So, we can replace $b$ by -4 and $x$ by -2 and solve for $a$ using the following equation as:

$x=\frac{-b}{2a}\\-2=\frac{-(-4)}{2a}\\-2(2)a=4\\-4a=4\\a=-1$

It means that the equation of the parabola is equal to:

$y=-1x^{2}-4x+3$
