Select all the intervals where f is decreasing

Answers

Answer 1

One Answer: Choice C) 0 < x < 1

==================================================

Explanation:

Let's go through the answer choices one at a time.

Choice A represents an increasing interval since the graph goes uphill as we move from left to right. The line through the points (-2, f(-2)) and (-1.5, f(-1.5)) has a positive slope. We can rule out choice A.Choice B is a similar story to choice A. The graph goes uphill when we move from x = -1 to x = 0, so the graph is increasing on the interval -1 < x < 0. We can rule out choice B.In contrast, choice C is a decreasing interval. Going from x = 0 to x = 1 has us move downhill. Choice C is the only answer.Choice D is false because choice C was shown to be true.

Answer 2

The correct option is C

What is a decreasing function?

A function whose value decreases as the independent variable increases over a given range is called a decreasing function.

Considering the options :

A) it represents an increasing interval since the graph goes uphill as we move from left to right. The line through the points (-2, f(-2)) and (-1.5, f(-1.5)) has a positive slope. We can rule out choice A.

B) It is a similar story to choice A. The graph goes uphill when we move from x = -1 to x = 0, so the graph is increasing on the interval -1 < x < 0. We can rule out choice B.

In contrast, C is a decreasing interval. Going from x = 0 to x = 1 has us move downhill. Choice C is the only answer.

Hence, the correct option is 0 < x < 1

5(x-1)=23 solve the equation

Answers

Answer: 28/5 or 5.6

Step-by-step explanation:

5(x-1) = 23 Distribute on the left side

5x - 5 = 23 Add 5 to both sides

+5 +5

5x = 28 Divide both sides by 5

x = 28/5

Answer:

x = 28/5

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Equality Properties

Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtract Property of Equality

Step-by-step explanation:

Step 1: Define

5(x - 1) = 23

Step 2: Solve for x

Divide 5 on both sides: x - 1 = 23/5Add 1 to both sides: x = 28/5

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x: 5(28/5 - 1) = 23(Parenthesis) Subtract: 5(23/5) = 23Multiply: 23 = 23

Here we see that 23 does indeed equal 23.

∴ x = 28/5 is the solution to the equation.

a rectangular box has length 20 cm width 6 cm and height 4 cm find how many cubes of side 2 cm that will fit into the box

Answers

Answer:

Step-by-step explanation:

Get the volume of the rectangular box

Volume of the rectangular box = length * width * height

Volume of the rectangular box = 20 * 6 * 4

Volume of the rectangular box = 480cm³

Get the volume of the cube;

Volume of the cube = l³

Volume of the cube = 2³

Volume of the cube = 8cm³

Amount of 2cm³ cube that will fit = volume of the box/volume of the cube

Amount of 2cm³ cube that will fit = 480/8

Amount of 2cm³ cube that will fit = 60

Hence 60 2cm³ cube will fit into the box

Bill has 5 cups of strawberries he uses 2 and 1/6 to make smoothies he uses the rest of the strawberries to make fruit cups he needs 2/3 cups of strawberries for each fruit cup how many fruit cups can he make

Answers

Answer: Total fruit cups made = [tex]4\dfrac14[/tex]

Step-by-step explanation:

Total cups of strawberries = 5

Cups used for smoothies = [tex]2\dfrac16=\dfrac{13}{6}[/tex]

Since rest of the strawberries are used to make fruit cups = [tex]5-\dfrac{13}{6}=\dfrac{30-13}{6}=\dfrac{17}{6}[/tex]

Cups of strawberries for each fruit cup = [tex]\dfrac23[/tex]

Total fruit cups made = (rest of the strawberries ) ÷(Cups of strawberries for each fruit cup)

[tex]=\dfrac{17}{6}\div \dfrac23\\\\=\dfrac{17}{6}\times\dfrac32\\\\=\dfrac{17}{4}\\\\=4\dfrac14[/tex]

∴ Total fruit cups made = [tex]4\dfrac14[/tex]

the graph shows the number of quarts picked the graph shows the number of quarts picked and amount of money paid by different customers

Answers

Answer:

Step-by-step explanation:

Part A

Since, line shown in the graph passes through origin (0, 0), relation between number of quarts picked (Q) and amount of money paid (M) will be proportional.

M ∝ Q

M = kQ [k = proportionality constant]

k = Slope of the line = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Since, line passes through two points (1, 3.5) and (2, 7),

k = [tex]\frac{7-3.5}{2-1}[/tex] = 3.5

Therefore, M = 3.5Q

This relation states that "For each number of quarts picked, $3.5 is to be paid"

Part B

Equation that represents the proportional relation,

y = 3.5x

Or Amount of money paid = 3.5(Number of quarts picked)
