Answer: x=-3
Step-by-step explanation:
So we can say 2 square/3 square to whole power 4= 4/9 to the whole power 1, so -7*1=-7
2x-1=-7
x=-3
The answer 2+(-3) well I just need to add more so don’t pay attention to this
Answer:
The relation which is a function is the one in which none of the first coordinates repeated.
Step-by-step explanation:
Note the binomial expansion,
(<em>a</em> + 1/<em>a</em>)³ = <em>a</em> ³ + 3<em>a</em> + 3/<em>a</em> + 1/<em>a</em> ³
so
<em>a</em> ³ + 1/<em>a</em> ³ = (<em>a</em> + 1/<em>a</em>)³ - 3 (<em>a</em> + 1/<em>a</em>)
Similarly,
(<em>a</em> + 1/<em>a</em>)² = <em>a</em> ² + 2 + 1/<em>a</em> ²
We're given <em>a</em> ² + 1/<em>a</em> ² = 79, so
(<em>a</em> + 1/<em>a</em>)² - 2 = 79
(<em>a</em> + 1/<em>a</em>)² = 81
<em>a</em> + 1/<em>a</em> = ±9
but <em>a</em> > 0, so we ignore the negative solution.
Then
<em>a</em> ³ + 1/<em>a</em> ³ = 9³ - 3×9 = 702
The correct answer is: True
A parallelogram means that the lines will not intersect.
As you can see the ^ on both sides witch indicates that they will not touch.
Hope this helps! :3
