f(x) = 5x + 1
f(4) = 5 * 4 + 1
f(4) = 20 + 1
f(4) = 21
g(x) = 2x² - 3x +1
g(5) = 5 * 5² - 3 * 5 + 1
g(5) = 125 - 15 + 1
g(5) = 111
f(4) + g(5) = 21 + 111 = 132

Answer:
5
Step-by-step explanation:
8(3 + a) = 64
3 + a = 8
a = 5
Answer:
10x + 7y = 2
Step-by-step explanation:
Slope = (6 + 4)/(-4 - 3) = -10/7
Equation:
y + 4 = -10/7(x - 3)
7(y + 4) = - 10(x - 3)
7y + 28 = -10x + 30
10x + 7y = 30 - 28
10x + 7y = 2
Answer: Option B
Step-by-step explanation:
By definition, only those functions that are one to one have an inverse function.
A function is one by one if there are not two different input values,
and
, that have the same output value y
Note that the function
is not a one-to-one function
When x=2 
When x=8 
Note that the function
is not a one-to-one function
When x=1 
When x=-1 
Note that the function
is not a one-to-one function
When x=1 
When x=-1 
Then the answer is the option B.
You can verify that The function
is a one-to-one function and therefore its inverse is a function
