Answer:
Both are equal to 
Step-by-step explanation:
If the exponent is negative we can turn it into a fraction and make it positive.
This means the number goes to the denominator and the numerator becomes one. Therefore the following.

Answer:
x = 26
Step-by-step explanation:
There is 360 degrees in a full revolution.
There are 7 sides/edges/vertices in a heptagon.
360/7 = 51.42857143
The degree of an angle in a regular heptagon is thus 51.42857143 degrees.
75 x 15= 1,125
1,125/100=11.25
75-11.25= 63.75
The answer is (3,-4). On a graph you see it is right in the middle. Hope this helps.
