help me solve 4x - 3 < 7

Answers

Answer:

x< 2 1/2

Step-by-step explanation:

[tex]4x - 3 < 7[/tex]

Add 3 to both sides of the equation

[tex]4x - 3 + 3 < 7 + 3 \\ 4x < 7 + 3 \\ 4x < 10[/tex]

Divide both sides of the equation by 4

[tex] \frac{4x}{4} < \frac{10}{4} [/tex]

Simplify

[tex]x < \frac{5}{2} [/tex]

The solution to the inequality is x < 5/2.

What is an inequality?

In Mathematics and Geometry, an inequality is a relation that compares two (2) or more numerical data, number, and variables in an algebraic equation based on any of the inequality symbols;

Greater than (>).Less than or equal to (≤).Less than (<).Greater than or equal to (≥).

In this scenario and exercise, we would determine the solution set to the given inequality for x in parts as follows;

4x - 3 < 7

By adding 3 to both sides of the inequality, we have:

4x - 3 + 3 < 7 + 3

4x < 10

x < 10/4

x < 5/2.

The diagonal of a square is 10m long. What is the length of the side of the square?(Give your answer to the nearest cm)

Answers

Answer: 7 cm

Step-by-step explanation: The formula for this type of question is; √2×d÷2 where d stands for the diagonal so, √2×10÷2 = 7.071067812, to the nearest cm is 7cm.

Answer:

7 cm

Step-by-step explanation:

The diagonal divides the square into 2 right triangles.

Using Pythagoras' identity with the diagonal as the hypotenuse.

let x be the side of the square, then

x² + x² = 10²

2x² = 100 ( divide both sides by 2 )

x² = 50 ( take the square root of both sides )

x = [tex]\sqrt{50}[/tex] ≈ 7 cm ( to the nearest cm )

What are rational numbers?

A number that can be expressed as an integer or the quotient of an integer divided by a nonzero integer.

What are irrational numbers?

Irrational number, any real number that cannot be expressed as the quotient of two integers.

How to find which expressions given equal a rational number?

Firstly, we know that π is an irrational number .

So π x √4 = 2π

2π is an irrational number and so option A cannot represent a rational number.

2/3 + 4/3 = 6/3 = 2

Since 2 is a rational number, we can say option b represents a rational number

[tex]\sqrt{36} + \sqrt{5}[/tex]

= 6 + [tex]\sqrt{5}[/tex]

We, know that  [tex]\sqrt{5}[/tex] is an irrational number , So option C cannot represent a rational number.

[tex]\sqrt{3} - \sqrt{3} = 0[/tex]

0 is a rational number

So, option D represents a rational number.

[tex](\sqrt{49} )(\sqrt{1} ) \\= 7[/tex]

7 is a rational number and so option E represents a rational number.

PLEASE HELP ME!!. The local store where Tim shops charges 7% sales tax for clothing. Complete the table by figuring the cost of jeans after sales tax is applied. The first row has been done for you

Answers

Step-by-step explanation:

for 1 jeans

7% tax=7/100×25.68

=1.7976

So 1.7976$ is charged on one jeans.

7% tax for 2 jeans =2×1.7976

=3.5952$

Total price=3.5952+25.68

=29.2752

7% tax for 3 jeans=3×1.7976

=5.3928

Total price=5.3928+25.68

=31.0728

Hope this answer will help you

Answer:

$51.36

$77.04

Step-by-step explanation:

Multiply the cost of the number of pairs of jeans by the sales tax amount, 7%.

cost of 2 pairs:   48 + 7/100 x 48 = $51.36

 

cost of 3 pairs:   72 + 7/100 x 72 = $77.04

Consider the function f(x) = x2 – 331. Chivonne claims a domain restriction x ≥ 0 produces the inverse function f–1(x) = StartRoot x minus 331 EndRoot . Which statement describes whether Chivonne is correct? The expression for f–1(x) is correct, but the domain restriction is not. The domain restriction is correct, but the expression for f–1(x) is not. Both the expression for f–1(x) and the domain restriction are correct. Neither the domain restriction nor the expression for f–1(x) is correct.

Answers

Answer:

The correct option is;

The domain restriction is correct but the expression for f⁻¹(x) is not

Step-by-step explanation:

The expression for the function is given as follows;

f(x) = x² - 331

The inverse function suggested = f⁻¹(x) = √(x-331)

The domain restriction is x ≥ 0

The inverse function if given as follows;

y = x² - 331 (Interchange x and y to get)

x = y² - 331

x + 331 = y²

y = ±√(x + 331)

Given that the domain restriction has been put as x ≥ 0, we select the + case to give;

f⁻¹(x) = √(x + 331)

Therefore, the domain restriction is correct but the expression for f⁻¹(x) is not.

Answer: B

The domain restriction is correct, but the expression for f–1(x) is not.

Determine NO

Since O is a segment on NP, we have that

I go and come with a strange liberty in Nature, a part of herself. As I walk along the stony shore of the pond in my shirt sleeves, though it is cool as well as cloudy and windy, and I see nothing special to attract me, all the elements are unusually congenial to me. The bullfrogs trump to usher in the night, and the note of the whippoorwill is borne on the rippling wind from over the water. Sympathy with the fluttering alder and poplar leaves almost takes away my breath; yet, like the lake, my serenity is rippled but not ruffled. These small waves raised by the evening wind are as remote from storm as the smooth reflecting surface. Though it is now dark, the wind still blows and roars in the wood, the waves still dash, and some creatures lull the rest with their notes. The repose is never complete. The wildest animals do not repose, but seek their prey now; the fox, and skunk, and rabbit, now roam the fields and woods without fear. They are Natures watchmen, links which connect the days of animated life. . . . Some of my pleasantest hours were during the long rain storms in the spring or fall, which confined me to the house for the afternoon as well as the forenoon, soothed by their ceaseless roar and pelting; when an early twilight ushered in a long evening in which many thoughts had time to take root and unfold themselves. . . . Men frequently say to me, I should think you would feel lonesome down there, and want to be nearer to folks, rainy and snowy days and nights especially. I am tempted to reply to such,This whole earth which we inhabit is but a point in space.
