Pretend that the inequality symbol is a equal sign. Divide 2 on both sides

it should look like this:|x+10| > 3 (Reason being you are trying to isolate the absolute value symbol so you divide 2 on both sides and 9 divided by 2 is 3)

Now take the absolute value of both sides. (You should still have the same answer you are just getting rid of the absolute value symbol) so now it should look like this : x+10>9

Subtract 10 on both sides ( reason being you are trying to isolate the variable now)

so your answer is x>-1

(The symbol is suppose to be greater than or equal to symbol...im on my laptop & I dont have that button)

I hope this helps!

2(x+10) >= 9

2x + 20 >= 9

2x >= -11

x >= -11/2

-2(x+10) >= 9

-2x - 20 >= 9

-2x >= 29

x <= -29/2

Answer

x <= -29/2 or x >= -11/2

Your plan was to be on the road by 9 A.M. but you did not leave the garage until 10 A.M. You then drove with the cruise control

Wittaler [7]

Answer:

The average speed over the time interval from 9 A.M. to noon was of 33.33 mph.

Step-by-step explanation:

The average speed is given by the following equation:

$v = \frac{d}{t}$

From 10A.M. to noon.

You traveled at 50mph during 2 hours. So how long you traveled?

$50 = \frac{d}{2}$

$d = 50*2$

$d = 100$

You traveled 100 miles.

What was your average speed over the time interval from 9 A.M. to noon

From 9 A.M. to 10 A.M, you did not travel.

From 10 P.M. to noon, 100 miles.

So 100 miles during 3 hours.

$v = \frac{d}{t} = \frac{100}{3} = 33.33$

The average speed over the time interval from 9 A.M. to noon was of 33.33 mph.

At 2:00 pm there are 350 freshmen and 200 sophomores at a school carnival. After 2:00 pm 20 freshman leave every hour and 35 sop

dmitriy555 [2]

Answer:

160:340

Step-by-step explanation:

The hours between 2:00pm and 4:00pm is 2 hours. If originally 350 freshman and 200 sophomores are at the carnival, and 20 freshman leave every hour, we can determine how many freshman left in 2 hours:

$=20\cdot{2}=40$

and if 35 sophomores arrive every half our, we know that for every two hours there is 4 half hours, therefore:

$=35\cdot{4}=140$

The amount of freshman at 4:00pm:

$200-40=160$

and the amount of sophomores:

$200+140=340$

the ratio is 160:340

The data shown on the scatter plot below demonstrates the relationship between the time of day and the total number

viva [34]

Answer:

Good question! The correct answer is a) increases and b) increases.

While the pair of answers a) decreases and b) decreases or the pair a) stays the same and b) stays the same would be technically correct answers, this is the best way of describing the trend of the scatter plot; typically, trends are described by how the dependent or y-variable responds to the independent or x-variable increasing.
