Answer:
x = 2.5
or
x = 
Step-by-step explanation:
18x + 6 + 4 = 55
18x + 10 = 55
18x = 55 - 10
18x = 45
x = 2.5

Answer: g(1) is 1.
Step-by-step explanation:
If we are solving for g of 1 then the first equation can't be used to solve for g of 1 because it only works in x is equal to -2.
The same way the second function will not work because x has to equal to -1.
But in the last function which is written as a polynomial it will work for this situation because x is not equal to -2 or -1 so apart from those numbers every number will work the same way 1 will work.
So plot 1 into the function and solve for it .
g(1) = 1^3 - 1^2 + 1
g(1)= 1 - 1 + 1
g(1)= 1
Answer:
You calculate the derivative of a given function f(x), f'(x), and see when it is positive:
f'(x) > 0
It will give you an interval of values where the slope is positive.
40/50 is the ratio because the cos formula is adjacent over hypotenuse and you can reduce it to 4/5 as a fraction :)
