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
