Which number line shows the solution to inequality 3x – 3 < 12?

Answers

Answer:

A

Step-by-step explanation:

The Graph "A" show the value of x in  inequality 3x – 3 < 12

What is inequality?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

What does open circle and close circle shows in graph?

A closed circle indicates "greater than or equal to" or "less than or equal to," while and open circle indicates "greater than" or "less than".

According to the question

Given inequality 3x – 3 < 12

Solving for x

3x – 3 < 12

3x < 12 + 3

3x < 15

x < 5

Open circle will be used to show the greater than sign

Therefore,

Graph  A shows the inequality .

Hence, the Graph "A" show the value of x in  inequality 3x – 3 < 12

Answers

Answer:

[tex]f^{-1}[/tex] (22) = 7

Step-by-step explanation:

The inverse function maps the output of the function back to its input

f(7) = 22 means when input is 7 the output is 22

The inverse maps the output 22 back to the input 7 , that is

The formula

gives the number of calories C in a serving of food that contains f grams of fat, p grams of protein, and c grams of carbohydrate.†

Find the number of grams of protein in an 8-ounce serving of vanilla yogurt that contains 179 calories, 3 g of fat, and 31 g of carbohydrate.
g

Answers

Answer:

7 grams of protein

Step-by-step explanation:

C = 9f + 4p + 4c

Plug the given information into the given formula

179 = 9(3) + 4p + 4(31)

Use PEMDAS

179 = 27 + 4p + 124

Combine like terms

179 = 151 + 4p

Subtract both sides by 151 to isolate variable p

179 - 151 = 4p

28 = 4p

Divide both sides by 4 to isolate variable p

28 ÷ 4 = p

7 = p
