How many integers n satisfy the inequality 3n² - 4≤44?

Mathematics

Margaret [11]3 years ago

Answer:

The possible values of n  for n ≤ +4  =  (-∞,+4]

The possible values of n for  n ≤ -4  =  (-∞,-4]

Step-by-step explanation:

Here, the given inequality is:

3n^2 - 4 \leq 44

Firstly, let us solve the given inequality for the desirable value of n.

3n^2 - 4 \leq 44

Adding 4 on both sides, we get:

3n^2 - 4 + 4 \leq 44 + 4

3n^2  \leq 48

or, n^2 \leq \frac{48}{3}\implies n^2 \leq 16\\

⇒   n ≤ +4  or  n ≤ -4

So, the possible values of n  for  n ≤ +4  =  (-∞,+4]

And,  the possible values of n  for  n ≤ -4  =  (-∞,-4]

So, we can pick any of the integer values from the both defined sets.

Please find the perpendicular line slope equation please! Thanks!
lana66690 [7]

We need to convert this equation to slope-intercept form first.

We can do that by solving for y.

x - 5y = 15

<em><u>Add 5y to both sides.</u></em>

x = 5y + 15

<em><u>Subtract 15 from both sides.</u></em>

x - 15 = 5y

<em><u>Divide both sides by 5.</u></em>

y = 1/5x - 3

We now know the slope is 1/5.

The slope of the line perpendicular to the line with a slope of 1/5 is -5.

The slope of a perpendicular line is the negative reciprocal of the original slope.

Using a graphing calculator, we know the y-intercept of the line that is perpendicular to the original line must have a y-intercept of -6 to run through the points (-2, 5).

The equation of the new line is y = -5x - 6.
