Answer:
g(-1) = -5
g(2a+1) = 16a+11
Step-by-step explanation:
Substitute the given value into the function and evaluate.
So for g(x) = 8x+3
You substitute g(-1)
So g(-1) = 8(-1)+3
That is how you get -5
Then g(2a+1)
So g(2a+1) = 8(2a+1)+3
Thats how you get 16a+11

Answer:
Step-by-step explanation:
Given the equation 4x²+ 49y² = 196
a) Differentiating implicitly with respect to y, we have;

b) To solve the equation explicitly for y and differentiate to get dy/dx in terms of x,
First let is make y the subject of the formula from the equation;
If 4x²+ 49y² = 196
49y² = 196 - 4x²

Differentiating y with respect to x using the chain rule;
Let 





c) From the solution of the implicit differentiation in (a)

Substituting
into the equation to confirm the answer of (b) can be shown as follows

This shows that the answer in a and b are consistent.
Answer:
Step-by-step explanation:
Let x represents the amount that the customer pays per hour
for renting the vacuum cleaner before returning it.
Let y represent the flat rate that the store charges a customer for renting the vacuum cleaner.
Let F represent the amount that the store charges a customer for renting the vacuum cleaner for x hours.
A linear function F for the total retail cost of a vacuum cleaner would be
F(x) = x + y
If the customer rents it for n hours, the total amount becomes
F(x) = nx + y
