SVETLANKA909090 [29]

Answer:

$\frac{-5}{3}$

Step-by-step explanation:

3(2 + 4x) = -7 x 2 Distribute the 3

6 + 12x = -14 Subtract 6 from both sides of the equation

12x = -20 Divide both sides by 12

x = $\frac{-20}{12}$ Divide the top and the bottom of the fraction by 4

x = $\frac{-5}{3}$

What is the rule when multiplying or dividing by a negative number to solve inequalities?

Alika [10]

You flip the inequality.
Example: if x > -y and you divide both sides by (-1) then you flip the inequality so: -x < y

The equation of the parabola is:

$y = 24x^2$

---------------------------

The equation of a parabola of vertex (h,k) and focus (0,f) is given by:

$y = 4p(x - h)^2 + k^2$

Vertex at the origin means that $h = 0, k = 0$ .
Focus (0,6) means that $p = 6$

Thus, the equation of the parabola is:

$y = 4p(x - h)^2 + k^2$

$y = 4(6)(x - 0)^2 + 0^2$

$y = 24x^2$
