Find the solution set of this inequality|10x+20| ≤10

Answers

Answer:

solution is

[-3,-1]

Step-by-step explanation:

we are given

$|10x+20|\leq 10$

Firstly, we will find critical values

so, let's assume it is equal

$|10x+20|= 10$

now, we can break absolute sign

For $|10x+20|= -(10x+20)$ :

$-(10x+20)= 10$

we can solve for x

$-10x-20= 10$

Add both sides by 20

$-10x-20+20= 10+20$

$-10x= 30$

Divide both sides by -10

and we get

$x=-3$

For $|10x+20|= (10x+20)$ :

$(10x+20)= 10$

we can solve for x

$10x+20= 10$

Subtract both sides by 20

$10x+20-20= 10-20$

$10x= -10$

Divide both sides by 10

and we get

$x=-1$

so, critical values are

$x=-3$

$x=-1$

now, we can draw a number line and locate these values

and then we can check inequality on each intervals

For $(-\infty,-3)$ :

We can select any random value from this interval and plug that in inequality

and we get

we can plug x=-5

$|10* -5+20|\leq 10$

$|-50+20|\leq 10$

$30\leq 10$

so, this is FALSE

For $[-3,-1]$ :

We can select any random value from this interval and plug that in inequality

and we get

we can plug x=-2

$|10* -2+20|\leq 10$

$|-20+20|\leq 10$

$0\leq 10$

so, this is TRUE

For $(-1,\infty)$ :

We can select any random value from this interval and plug that in inequality

and we get

we can plug x=0

$|10* 0+20|\leq 10$

$|0+20|\leq 10$

$20\leq 10$

so, this is FALSE

so, solution is

[-3,-1]

Which expression could be used to determine the cost of a $50 video game after a 20 percent discount?

Answers

The price of a video game is now 50 dollars after the 20% discount.The question is what is the expression to be able to solve that amount before the 20% discount.=> 100% - 20% = 80%=> 50 is the 80% => 80% = .80Expression = .80 = 50, where x is the unknown number that we need to know.
=> .80 = 50 => .80x / .80 = 50 / .80=> x = 62.5 dollars is the original price of the said video game on sale.

50x.2 is the correct expression.

What is 16.81 rounded to the nearest tenth and whole #

Answers

16.81 rounded to the nearest tenth would be 16.8 because 1 is less than 5 so the 8 would stay the same
16.81 rounded to the neared whole number would be 17 because 8 is more than 5 so 6 is rounded up

Hope this helped! :))

The tenths place is the place right after the decimal point. When rounding, you look at the next place over (which would be the hundredths place in this case) and look at the number closely. If it is 5 or more than 5, the hundredths place disappears and becomes 16.8. When rounding to a whole number, you do practically the same thing but you look at the ones place (the place right before the decimal point) and look at the next place over (tenths place). Again, is it 5 or more? Yes, so you round up to 17 and get rid of the tenths place and everything after.
