Answer:

x ≤ 7.5

Step-by-step explanation:

First, get x alone by multiplying both sides by 3 (to get rid of the fraction)

3 (1/3x) ≥ 3(2.5)

x ≤ 7.5

(The sign will flip whenever you multiply or divide in an inequality)

Since the sign is 'less than or <u>equal to</u>' you need a closed dot on 7.5, and it will be a ray pointing left, because x will be a number smaller (aka less than) than 7.5

-3x^2-168 solve the quadratic equation

vlabodo [156]

Answer:

$x=+2i\sqrt{14}\ \ \,x=-2i\sqrt{14}$

Step-by-step explanation:

$-3x^2-168$

The first step in solving this equation is the factor, remove a factor that both the quadratic and constant term have in common. In this case, such a term would be (-3),

$-3(x^2+56)$

Now set the equation equal to zero so that one can use the zero product property. The zero product property states that any number times zero equals zero.

$-3(x^2+56)=0$
