You can first multiply your coefficients (7x9), which gives you 63. You can then simplify the exponents by using the rule that when two terms with the same variable are being multiplied, you can simplify by adding exponents. Since 7+3= 10, your simplified answer would be 63x^10 :) hope it helped!
You could give all of the fractions a common denominator. You could also solve each of them (1/2=0.5) to see their value and order them through the value.
Answer:
138°
Step-by-step explanation:
x+115°=6x° [ being vertically opposite angle]
or, 115=6x - x
or, 115=5x
or, 115/5 =x
or, x=23
Then,
x+115°
= 23+115°
=138°

Answer:
As x —> negative infinity, f(x) —> negative infinity
As x —> positive infinity, f(x) —> positive infinity.
Step-by-step explanation:

An odd-degree function, meaning that the graph starts from negative infinity at x —> negative infinity and positive infinity at x —> positive infinity.
As x —> negative infinity, f(x) —> negative infinity
As x —> positive infinity, f(x) —> positive infinity.
An odd-degree function is an one-to-one function so whenever x approaches positive, f(x) will also approach positive.
