Vertical angles equal each other so (13x-85) = 97
we can solve for x:
13x-85 = 97
add 85 to each side:
13x = 182
divide both sides by 13
x = 182 / 13
x = 14
z and 97 are supplementary angles and need to equal 180 degrees
z = 180 - 97 = 83
Answer:
C. 1/(x^2 +1) > 0
Step-by-step explanation:
The cube of a negative number is negative, eliminating choices B and D for certain negative values of x.
1/x^2 is undefined for x=0, so cannot be compared to zero.
The value 1/(x^2+1) is positive everywhere, so that is the expression you're looking for.
1/(x^2 +1) > 0
