Three times the square of a certain positive number exceeds six times the number by nine. find the number:

1 answer:

4 0

With the number being x, we have 3x^2>6(x/9). Expanding, we get 3x^2>6x/9 and 3x^2>2x/3. Dividing by x, we get 3x>2/3 and dividing by 3 we get x>2/9

Help???<br> Its a two step inequality problem. I dunno what X equals too.

Answer:

$x \geq -1$

Step-by-step explanation:

$-4x + 2 \geq -6x$

Add $6x$ to both sides:

$-4x + 2 + 6x \geq -6x + 6x$

$2x + 2 \geq 0$

Subtract 2 from both sides:

$2x + 2 - 2 \geq 0 - 2$

$2x \geq -2$

Divide both side by 2:

$\frac{2x}{2} \geq \frac{-2}{2}$

$x \geq -1$

I need help! Find the equation of a line parallel to 3x-3y=5 that contains the point (-1,-5). Write the equation in slope Interc

Readme [11.4K]

the equation of the line is y= x-4

Step-by-step explanation:

so so the first thing that you're going to do is get y alone

-x-5=y

next you're going to find your slope which in this case is negative one.

after that in order to find the equation of a parallel line you're going to find the reciprocal of the slope.

so in this case the reciprocal is one.

next you're going to substitute in the cordinates to find the y intercept

x+b=y. (-1)+b= -5. (. b is the y intercept)

b= -4
