hen by 10 2. 11>-2 Add 5 to both sides, then add 3, then add (-4) 3. -4<-2 Subtract 6 from both sides, then 8, and then 2 4. -8<8 Divide both sides by -4, then by -2 5.

In the given question, we have to perform this experiment and test if the inequality is true or not.

Adding the same value to both sides of the inequality will not change the inequality sign

<h3>Inequality</h3>

data;

  • 4 < 7
  • 11 > - 2
  • -4 < - 2
  • -8 < 8

In the first case, we would do follow the process

6 * 7 * 4 < 7 * 7 * 6\\168 < 294

In the second case;

11 > - 2\\\\5 + 11 > -2 + 5\\3 + 16 > 3 + 3\\4+ 19 > 6 + 4\\23 > 10

In all the scenarios, the operations did not affect the inequality sign because we are doing it equally to all side and at the end of the day nullifies each other.

Find the value(s) of n if n^4=625.
Grace [21]
The answer is 5 and -5, because squaring a positive or negative number give the same value, so square rooting that number should give back those positive and negative value. THIS ONLY WORKS FOR WHEN THE SQUARE ROOT OR THE SQUARING IS AN EVEN NUMBER.

You have a summer job that pays time and a half for overtime. that is if you work more than 40 hours per week,your hourly wage f
Nataliya [291]
Your pay is described by a piecewise function p(t) where t is hours worked.
p(t)=\left\{\begin{array}{rcl}7t&\mbox{for}&t\leq40\\10.5t-140&\mbox{for}&t>40\end{array}\right.

The domain of this function is the number of hours you can work in a week—zero to 168. The range is the set of values p(t) can take on, which we have said is p(0) to p(168). This problem, however, is asking for the range for a typical 40-hour week. That will be p(0) to p(40): the interval [0, 280].

I really need help with this it’s on Aleks
liraira [26]

Answer:

y = 2

Step-by-step explanation:

Given

\sqrt[3]{3y+2} + 4 = 6 ( subtract 4 from both sides )

\sqrt[3]{3y+2} = 2 ( cube both sides )

3y + 2 = 2³ = 8 ( subtract 2 from both sides )

3y = 6 ( divide both sides by 3 )

y = 2
