h(x) = x^2 - x + 7

Find f[g(5)]

A. 92
B. 2
C. 30
D. 242

Answers

Answer:

A

Step-by-step explanation:

Evaluate g(5), then use the value obtained to evaluate f(x) , that is

g(5) = 2(5)² - 4(5) = 2(25) - 20 = 50 - 20 = 30, then

f(30) = 3(30) + 2 = 90 + 2 = 92

can some please help me with this

Answers

Answer:

x = 25

Step-by-step explanation:

3x + 5 + 5x - 25 = 180 (collect like terms)

8x - 20 = 180 (add 20 on both sides)

8x = 200 (divide by 8 on both sides)

x = 25

Since they are supplementary that mean together they add up to 180 so that's why I added them together.

Carrie and nine of her friends go out to dinner. The total bill comes to $200. They decide to leave a 15% tip. Each person will contribute an equal amount to the total tip. What each person should contribute

Answers

Answer:

$3

Step-by-step explanation:

To find the value of the tip, multiply 200 by 15%.

200 x 15% = 30

Divide the tip by the number of people at the dinner (Carrie plus 9 friends = 10 people)

30 / 10 = 3

Each person should contribute $3 toward the tip.

Each person will contribute $23.

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Total Bill= $200

Tip= 15%

So, the amount of bill be paid after tip

= 200+ 200 x 15%

= 200+ 200 x 15/100

= 230

Now, each of them have to pay

= 230/ 10

= $23

Hence, Each of them paid $23.
