Answer:

a. x + 2 ≤ 6 or x + 2 ≥ 10 b. x  ≤ 4 or x  ≥ 8

Step-by-step explanation:

a. Write a compound inequality

Let x be the number.

Since x + 2 is no more than 6 then x + 2 ≤ 6 and x + 2 is no less than 10 then x + 2 ≥ 10

So, the compound inequality is x + 2 ≤ 6 or x + 2 ≥ 10

b. Solve the inequality

Solving each inequality, we have,

x + 2 ≤ 6

x  ≤ 6 - 2

x  ≤ 4

x + 2 ≥ 10

x  ≥ 10 - 2

x  ≥ 8

So,  x  ≤ 4 or x  ≥ 8

Answer:

X=32.666

Step-by-step explanation:

12(x-2)+3x=12(x+6)+2

12x - 25 + 3x = 12x + 72 +2

15x-24=12x+74

15x=12x+98

3x=98

x=32.666

Hope this helped!

Answer:

x=32.67

Step-by-step explanation:

12(x-2)+3x=12(x+6)+2

12x-24+3x=12x+72+2

simplify

15x-24=12x+74

15x-12x-24=12x-12x+74

3x-24=74

3x-24+24=74+24

3x=98

x=32.67

Answer:

Step-by-step explanation:

The question asks for f(3).  f(3) is the y value.  "3" is the x value.  In other words the question asks, "What is the value of y when x is 3?"

When x is 3, y=7.

Answer: The perimeter of the large rectangle measured 75 feet.

Step-by-step explanation:

For two similar rectangles,

[tex]\dfrac{\text{Perimeter of image }}{\text{Perimeter of pre-image }}=\dfrac{3}{2}[/tex]

The perimeter of the small rectangle is 50 feet.

Given ratio between two similar rectangles: 3:2

So,

[tex]\dfrac{\text{perimeter of large rectangle}}{\text{perimeter of small rectangle}}=\dfrac{3}{2}\\\\\Rightarrow\ \dfrac{\text{perimeter of large rectangle}}{50}=\dfrac{3}{2}\\\\\Rightarrow\ \text{Perimeter of large rectangle} =\dfrac{3}{2}\times50\\\\\Rightarrow\ \text{Perimeter of large rectangle} =75[/tex]

Hence, the perimeter of the large rectangle measured 75 feet.

The perimeter of a rectangle is the sum of the dimension of the rectangle

The ratio of the side length is given as:

[tex]Ratio = 3 : 2[/tex]

Represent the perimeters of both rectangles with

P1 and P2.

So, we have:

[tex]P1 : P2 = 3 : 2[/tex]

The smaller rectangle has a perimeter of 50 feet.

So, we have:

[tex]P1 : 50 = 3 : 2[/tex]

Express as fraction

[tex]\frac{P1 }{ 50 }= \frac 3 2[/tex]

Multiply both sides by 50

[tex]P1= \frac 3 2 \times 50[/tex]

[tex]P1= 75[/tex]

Hence, the perimeter of the larger rectangle is 75 feet

Answer:

392cm³

Step-by-step explanation:

First, we need to find what fraction of the whole volume was just added. We started with 4/7 and ended up with 3/4, so we can take the difference of the two to find the fractional part added:

[tex]\frac{3}{4}-\frac{4}{7} =\\\\\frac{21}{28}-\frac{16}{28} =\frac{5}{28}[/tex]

So, that 70cm³ represents 5/28 of the whole glass. If 70cm³ is 5/28 of the glass's volume, then 70/5 = 14cm³ must be 1/28 of the volume. From here, we can simply multiply 14 by 28 to find the total volume, all 28/28 of it:

14 · 28 = 392cm²

Answer:

Part 1

The given information represented as a function, f(x) is;

f(x) = 150 - 10·x

Part 2

Please find attached the given information represented as a graph is created with Microsoft Excel

Part 3

Mrs. Dyal will run out of pencils after giving away pencils for 15 weeks

Step-by-step explanation:

The word problem relates to linear functions of the form f(x) = y = m·x + c

The given parameters are;

The number of pencils Mrs. Dyal has at the start of the year = 150 pencils

The number of pencils Mrs. Dyal gives away per week = 10 pencils

Part 1

Let "x" represent the number of weeks at which Mrs. Dyal is giving away the pencils

Given that she gives away 10 pencils each week, we have the function that represent the number of pencils remaining after "x" weeks is given as follows;

f(x) = 150 - 10×x.

The number of weeks, "x", that passes before Mrs. Dyal runs out of pencil (f(x) = 0) is given as follows;

f(x) = 0 = 150 - 10 × x

∴ 150 Pencils = 10 Pencils/Week × x

x = 150 Pencils/(10 Pencils/Week) = 15 Weeks

x = 15 Weeks

Therefore Mrs. Dyal will run out of Pencil at when x = 15 Weeks

Part 2

The function can be represented as a graph using the table of values as follows ;

Pencil remaining  [tex]{}[/tex]              Number of weeks

150                      [tex]{}[/tex]                    0

The domain = 0 ≤ x ≤ 15 {x ∈ N including 0}

The range = 0 ≤ f(x) ≤ 150

From the graph of the function created with Microsoft Excel, Mrs Dyal has no more Pencils left when x = 15 weeks
