Answers

Answer 1

Answer:

A) f(2) = 7/2

B) f'(2) = 5

Step-by-step explanation:

We are given that;

f(x) = (x + 5)/x

f'(x) = 5/(x - 1)

A) Now, f(2) will be gotten by Plugging in 2 for x in to f(x) equation;

f(2) = (2 + 5)/2

f(2) = 7/2

B) similarly, f'(2) will be gotten by Plugging in 2 for x in f'(x) equation. Thus;

f'(2) = 5/(2 - 1)

f'(2) = 5/1

f'(2) = 5

The anwser is A

By multiplying the second equation by -2, it makes the new equation -6x+2y = -8

When you add that to the first equation you get x=-5

What are the types of solutions of a system f linear equations?

If a system of equations only contains two linear equations with two variables, the system's equation can be graphed, the graph will have two straight lines, and the intersection point(s) of those lines will be the system's solution.

There are only three matching forms of solution for a given system of equations because there are only three different ways that two straight lines in the plane can graph.

Given, A linear system,

5x - 2y = 3...(1) and 3x - y = 4...(2)

Now, To eliminate one of the variables 'x' or 'y' we can apply arithmetic operations to the linear operations.

Now, If we Multiply the second equation by  - 2 and then add the result to the first equation we'll have,

- 6x + 2y = - 8

Now, Adding this to the eqn(1) variable 'y' gets cancelled and we have,

Solve 2( 4x - 1) = 18

Answers

the answer is 2.5

2 (4x - 1) = 18
8x - 2 = 18
8x = 20
x = 2.5

Answer:

x=2

Step-by-step explanation:

Simplifying

2(4x + 1) = 18

Reorder the terms:

2(1 + 4x) = 18

(1 * 2 + 4x * 2) = 18

(2 + 8x) = 18

Solving

2 + 8x = 18

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2' to each side of the equation.

2 + -2 + 8x = 18 + -2

Combine like terms: 2 + -2 = 0

0 + 8x = 18 + -2

8x = 18 + -2

Combine like terms: 18 + -2 = 16

8x = 16

Divide each side by '8'.

x = 2

Simplifying

x = 2

Roy and two friends are at a game center. Each person buys hot dogs for $3, fries for $2.49, and a drink for $2.50. They also have a coupon for $1 off each drink. Write an expression to represent the total cost. Then find the total cost.

Answers

Answer:

$20.97

Step-by-step explanation:

3 people, meaning to multiply each one by 3.

Total price of Hot Dogs= 9.00

Total price of Fries=7.47

Total price of Drinks=7.50
