An equation 3 (2x - 7) = 3
Part A: How many solutions does this equation have?
Part B: What are the solutions to this equation? Show your work.

Answer:-√ 5

Step-by-step explanation:

4√ 20 = 8√ 5
3√ 45 = 9√ 5
8√ 5 - 9√ 5 = -√ 5

Answer: 7x - 140

The expression 7(x-20) is a product of 7 and a grouping of x-20. To simplify this expression, we use the distributive property, which states that we can multiply the 7 by each term inside the grouping. So, 7(x-20) becomes 7x - 140. This is because 7x is the product of 7 and x, and 140 is the product of 7 and 20.

Step-by-step explanation:

The initial fee charged to customers for using the gym, given the graph showing the charges to customers is $ 20.

To find the initial membership fee, you should look at the y - intercept of the graph.

The y - intercept is the point where the x vale is 0 and this case this point shows the cost when the customers have not worked out in the gym for any hour yet.

This y - intercept is therefore $ 20 as this is the point on the graph where the value of x is 0.

There are other methods to write a division issue, such as using a / or a to denote "divided by." As a result, in the equation 473 / 2 = 1 the divisor is the quotient, the remainder is 236, and the divisor is 2.

Divide the dividend's first digit, which should be on the left, by the divisor, then write the result as the quotient on top. Write the difference below after subtracting the outcome from the digit. Bring down the dividend's next digit (if present).

Long division strategy: lengthy division techniques. The same symbols are used for long division as they are for short division: dividend (the number being divided) under the "bus stop," divisor (the number the dividend is being divided by), quotient (the solution) on top, and each place value aligned with the dividend.

Dividend Divisor = Quotient + Remainder is the formula for dividing two numbers.

Three letters will be selected from five letters. The number of possible selections is 10.

A combination is a method of picking elements from a collection where the order of selection is irrelevant. Assume we have three numbers P, Q, and R. The number of ways we can choose two numbers from each set is determined by combination.

Suppose we want to pick k elements from a set of n elements, then the number ways it can be chosen is:

C(n,k) = n! / k! (n-k)!

Where n! is n factorial.

In this case, there are 5 letters and we want to select three letters. Hence, k = 3, and n = 5.

C(5,3) = 5! / 3! (5-3)!

C(5,3) = 5! / (3! 2!) = 10

Thus, there are 10 possible selections.

The expression represents the area of the room not covered by the rug is A(x) = 2x² - 22x + 144.

Area of room = 3x² + 2x

Area of rug = x² + 24x - 144

We have to find the area of the room not covered by the rug.

Area of the room not covered by the rug = Area of the room - Area of rug

= (3x² + 2x) - (x² + 24x - 144)

= 3x² + 2x - x² - 24x + 144

= (3x² - x²) + (2x - 24x) + 144

a) Equation would be 5x + (x - 6) + (x - 6) = 180°

b) m∠1 = 180° and  m∠2 = 30°

What is the measure of angle?

The term "degree measure" refers to the measurement of an angle in degrees. Because one entire revolution equals 360°, it is divided into 360 parts. Each stage of the revolution represents a degree.

a) The angle measures in a triangle must add up to 180°.

Therefore, the equation to find x is:

        5x + (x - 6) + (x - 6) = 180°

b) Solving for x, we get:

x = 36

Therefore, angle m∠1 = (5x) = (5 * 36) = 180° (major angle)

angle m∠2 = (x - 6) = (36 - 6) = 30° (minor angle)

Answer: 30$

Step-by-step explanation:

To find the slope of the equation, you can use the formula (y2-y1)/(x2-x1). Plugging the points the question gives us we can get:

(205-100)/(5-2)

= 105 / 3

= 35

Plugging this information along with a point into the formula y = mx + b:

100 = 35*2 + b

100 = 70 + b

b = 30

y = 35x + 30

To double check this is correct:

y = 35 * 5 + 30

y = 175 + 30

y = 205

(5,205) is a point therefore y = 35x + 30 is the equation

Because the x of the graph represents the number of months, the initial membership fee would be when x = 0.

y = 35*0 + 30

y = 30$

The area, in square inches, will be 156.25π

You would require the radius in order to get the circle's area. You would enter the circumference (25) into the equation for the circle's circumference, which looks like this:

C = 2πr

25π = 2πr

Then you would figure out how to solve for r. (the radius)

25π = 2πr

12.5π = πr

12.5 = r  

After that, you would enter the radius into the equation for a circle's area.

A = π(r^2)

A = 12.5^2π

A = 156.25π

Due to the fact that meters were used as the unit of measurement, your response would be 156.25 meters.

The fourth option represents the reflection over the x-axis of f(x)=√x. The graph has been attached below. The solution has been obtained by the concept of reflections.

What is reflection?

A flip is the term for a reflection in geometry. The shape is mirrored in a reflection. The line of reflection is a line across which an image will reflect. A reflection is the shape's mirror image. Every point in a figure is said to reflect the other figure when they are all equally spaced apart from one another. The reflected picture should have the same size and shape as the original, but it faces the opposite way.

We are given the function f(x)=√x.

When we replace x with -x, then the graph of the resulting equation i.e.

f(x)=√-x is captured by reflecting the graph of f(x)=√x vertically across the x-axis.

What is trigonometric function?

Simply put, trigonometric functions also referred to as circular functions are the functions of a triangle's angle. This means that these trig functions provide the relationship between the angles and sides of a triangle.

The given trigonometric function is -

sec θ = 13/12

Sec function is written as the ratio of hypotenuse to adjacent.

sec θ = 1/cos θ

Cos function is written as the ratio of adjacent to hypotenuse.

cos θ = 12/13

To find the opposite, apply the Pythagoras theorem -

(Opposite)² = (Hypotenuse)² - (Adjacent)²

(Opposite)² = (13)² - (12)²

(Opposite)² = 169 - 144

Opposite = √25

Opposite = 5

Tan function is written as the ratio of opposite to adjacent.

tan θ = 5/12
