Answer:
Step-by-step explanation:
This is called "solving an inequality".
The inequality can flip:
< becomes >
> becomes <
≤ becomes ≥
≥ becomes ≤
This only happens when we multiply or divide both sides by a negative number, or when we swap everything from either sides.
The thing to remember if there are two of the inequalities, we have to do everything to both sides. The goal stays the same. Get the "X" by itself in the middle.
-17 < 5 - 2x <= 9
-5 -5 -5
------------------------
-22 < -2x <= 4
Now we have to divide the -2 on both sides. Remember! Dividing by a negative means we have to FLIP THE SIGNS!
-22 < -2x <= 4
/-2 /-2 /-2
----------------------
11 > x >= -2
And your final answer would be that.
It can also be written this way:
-2 <= x < 11
Answer: Rounded to the nearest tenths place, it is 3.7 meters.
Step-by-step explanation:
Using the above formula, let's multiply 2.5 times 2.5 and 4.5 times 4.5.
2.5 times 2.5, or 2.5 squared, equals 6.25
4.5 times 4.5, or 4.5 squared, equals 20.25
Now, let's subtract 20.25 minus 6.25. The difference is 14.00.
What is the square root of 14? It is 3.74165739. Let's round that number to the nearest tenths place.
What is the number in the tenths place? It is 7. And--what is the number that comes after it? Well, it is 4. Therefore, the 7 should stay a seven. If the number next to the tenths place was five or greater, then we should add one.
Answer: 3x^2+2x+2
