Question: 2c - 5 = 9
Answer: c = 7
Because the two angles on the right add to 180 degrees, we can create this system:
We can also prove that
, which, when solved, shows that
.
When plugged in to the original equation, we find that y = 105 degrees.
For # 1, the answer will be 1 because of the exponential rule
.
#2, the answer is going to be
because of the exponential rule
.
#3. I'm not sure that this could be simplified any further.
#4 To get the answer to this question, we must apply the distributive property, along with the exponential rule
. When we apply these properties, we'll get
For the other questions, they all apply the Laws of Exponents.
f(-10) = 4
f(-2) = 4
Since y is constant while x isnt we just dont need to put x
f(x) = 4
