The answer t our question is the first one
I just substituted he number one in every x
The original equation is equal to 147 when x equals to 1
And the first option is also equal to 147 when x equals to one
Answer:
if I remember correctly it would be a triangle.
Answer:
Real numbers are "closed" under multiplication
Irrational numbers are "not closed" under division
Integers are "closed" under subtraction
Positive ration numbers are "closed"
Hope this helps! :)
2 points=2%=0.02
205000×0.02=4,100 cost of 2 points
Closing costs is
4,100+450+575+600
=5,725....answer
Hope it helps!
For this case we must find an expression equivalent to:
![x ^ 3 * y ^ {- 7}](https://tex.z-dn.net/?f=x%20%5E%203%20%2A%20y%20%5E%20%7B-%207%7D)
By definition of power properties we have to meet:
![a ^ {-1} = \frac {1} {a ^ 1} = \frac {1} {a}](https://tex.z-dn.net/?f=a%20%5E%20%7B-1%7D%20%3D%20%5Cfrac%20%7B1%7D%20%7Ba%20%5E%201%7D%20%3D%20%5Cfrac%20%7B1%7D%20%7Ba%7D)
Then, we can rewrite the expression as:
![x ^ 3 * \frac {1} {y ^ 7} =\\\frac {x ^ 3} {y ^ 7}](https://tex.z-dn.net/?f=x%20%5E%203%20%2A%20%5Cfrac%20%7B1%7D%20%7By%20%5E%207%7D%20%3D%5C%5C%5Cfrac%20%7Bx%20%5E%203%7D%20%7By%20%5E%207%7D)
Answer:
![\frac {x ^ 3} {y ^ 7}](https://tex.z-dn.net/?f=%5Cfrac%20%7Bx%20%5E%203%7D%20%7By%20%5E%207%7D)
