Answer:

$\boxed{\bold{15x+78}}$

Step By Step Explanation:

Apply Rule - (-a) = a

$\bold{6\left(4x+12\right)-9x-18+4\cdot \:6}$

Multiply: 4 · 6 = 24

$\bold{6\left(4x+12\right)-9x-18+24}$

Expand $\bold{6\left(4x+12\right): \ 24x+72}$

= $\bold{24x+72-9x-18+24}$

Simplify $\bold{24x+72-9x-18+24}$

= $\bold{15x+78}$

Determine the direction that this parabola opens y=4x^2+8x+2

just olya [345]

For this case we have a quadratic equation of the form:
$ax ^ 2 + bx + c
$
What we must keep in mind to know which direction opens the parabola, is the value of a.
We have two options:
If a <0 the parabola opens down
If a> 0 the parabola opens up
We have the following equation:
$y = 4x ^ 2 + 8x + 2
$
We observed that:
$a = 4 (a\ \textgreater \ 0)
$
Therefore, the parable opens up.
Answer:
the direction that this parabola opens is:
Upwards

Answer:

(3,5)

1/3

Step-by-step explanation:

The equation is already in point-slope form. Therefore, both the point and slope can easily be found in the equation. Point slope form looks like $y-y_{1}=m\left(x-x_{1}\right)$ . In this the point is $(x_{1},y_{1})$ and the slope is m. So, the x value is 3 and the y value is 5, making the coordinate (3,5). Finally, the slope is 1/3.
