Find the y-intercept and the axis of symmetry of f(x)=ax2+2ax+3.

Sonbull [250]

Answer:

$y= cx^2 +dx +e$

We see that:

$c = a, d= 2a , e= 3$

The axis of symmetry is defined by this formula:

$X= - \frac{d}{2c}$

And replacing we got:

$X= -\frac{2a}{2a}= -1$

Thn the axis of symmetry would be X=-1

Step-by-step explanation:

For this case we have the following function:

$y = ax^2 +2ax +3$

If we compare this function with the general expression of a quadratic formula given by:

$y= cx^2 +dx +e$

We see that:

$c = a, d= 2a , e= 3$

The axis of symmetry is defined by this formula:

$X= - \frac{d}{2c}$

And replacing we got:

$X= -\frac{2a}{2a}= -1$

Thn the axis of symmetry would be X=-1

Zachery is solving the equation 3/4 (x - 8) = 12

Maru [420]

Answer:

3/4*x - 3/4*8=12

3/4x -6=12

3/4x=12+6

3/4x=18

x=24

Step-by-step explanation:

multiply 3/4 into the content inside the brackets

have -3/4*8 cross the equal sign changing its sign from - to +

divide both sides by 3/4

What is the solution of 9x-8=34x-12

Cerrena [4.2K]

Answer: x = 2/13

Step-by-step explanation:

9x-8=34x-12

Add 12 on both sides and you get

9x+4=34x

Subtract 9x from both sides and you get

4=26x

Divide 26 from both sides to get

X= 4/26
