Use the Distributive Property and simplify the expression. 6+4(3x – 2)+5

Anon25 [30]

First, we need to use the distributive property to simplify the expression. So, that means we have to multiply the 4 by all of the integers and variables inside the parentheses.

If done correctly, your expression should be 6+12x-8+5

Next, we should combine all of the constant terms (just numbers without variables), also known as combining like terms.

If done correctly, your expression should be 12x+3.

This matches answer B. 12x+3

Find the vertical asymptotes. 2x2 + 7x + 6 y = 3x2 + 10x - 8 * = [ [?], x=

Llana [10]

Answer:

$-\frac{77}{24}$

Step-by-step explanation:

1. rewrite the equation in standard form: $4\cdot \frac{3}{2}\left(y-\left(-\frac{41}{24}\right)\right)=\left(x-\left(-\frac{3}{2}\right)\right)^2$

2. find (h,k), the vertex. the vertex is $\left(h,\:k\right)=\left(-\frac{3}{2},\:-\frac{41}{24}\right)$

3. find the 'focal length' of the parabola - the focal length is the distance between the vertex and the focus. from the vertex we can see that the focal length, p, = 3/2

4. Parabola is symmetric around the y-axis and so the asymptote is a line parallel to the x-axis, a distance p from the $\left(-\frac{3}{2},\:-\frac{41}{24}\right)$ y coordinate which is at $-\frac{41}{24}\right)$ . Set up the equation:
