Seth buys last year's best-selling novel, in hardcover, for $16.90. This is with a 35% discount from the original price. What was the original price of the novel?

The answer would be 4/21 if divided 2/7 by 1.5 which is the correct option (C).

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

/ Division operation: Divides left-hand operand by right-hand operand

For example 4/2 = 2

We have to determine the divide 2/7 by 1.5

⇒ 2/7 ÷ 1.5

Here 1.5 = 3/2

⇒ 2/7 ÷ 3/2

Apply the division operation between both term

⇒ (2/7)/(3/2)

Reciprocal the terms, we get

⇒ (2/7)×(2/3)

⇒ (2×2)/(7×3)

⇒ 4/21

Therefore, the answer would be 4/21

The equation of the line tangent to the curve at x = 11 is y = (5 / 432) · x - 43 / 432.

Herein we have a rational function, of which we must derive the equation of the line tangent to the curve at a given point. First, find the first derivative of the function by derivative rules:

f'(x) = [(6 · x + 6) - 6 · (x - 9)] / (6 · x + 6)²

f'(x) = 60 / (6 · x + 6)²

Second, evaluate the first derivative of the function:

f'(11) = 60 / (6 · 11 + 6)²

f'(11) = 5 / 432

This value represents the slope of the tangent line.

Third, calculate the y-value of the curve:

f(11) = (11 - 9) / (6 · 11 + 6)

f(11) = 1 / 36

Fourth, determine the intercept of the tangent line:

b = 1 / 36 - (5 / 432) · (11)

b = - 43 / 432

The equation of the line tangent to the curve at x = 11 is y = (5 / 432) · x - 43 / 432.

Answer:

The function f defined by the formula f(x) = 2x +1 can be expressed as: f(4) = 9; f(-5) = - 9, f(0) = 1,

The function of a function defines and explains the relationship between two different variables. From the given information, we are meant to replace x with the following given options and solve for the value of x.

f(4) = 2(4) + 1

f(4) = 8 + 1

f(4) = 9

f(-5) = 2(-5) + 1

f(-5) = -10 + 1

f(-5) = - 9

f(0) = 2(0) + 1

f(0) = 0 + 1

f(0) = 1

Step-by-step explanation:

Basically first you have to check what the f(x) fits into what category.

The picture shows different equations based on what the f(x) is.

In this case, f(x) is 7. So first check is 7 greater than 5, YES. But check with the next one too. Is 7 less than or equal to 5, NOPE

So your equation your going to be substituting with is x squared-x

Little bit stuck still? Here:

What is 7 to the power of 2 is 7x7=49

Then, 49-7=42

42 is your answer. If this is for RSM ENTER ONLY 42 INTO THE PORTAL.

Given conditions:

6th term (T6) = -2

first term (a) = 18

n = 6, r = ?

Formula for finding the nth term of a GP:

Where:

T = the given value for the number of term(s)

n = the given number of term

a = The first term

r = The common ratio

Replacing for the values:

Dividing both sides by 18, we have:

The length of each equal side of the isosceles right triangle will be 11 cm.

The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.

The Pythagoras theorem formula is given as

H² = P² + B²

The hypotenuse of an isosceles right triangle is √242 cm.

In an isosceles right triangle, the two legs of the isosceles right triangle are congruent.

Let x be the other leg.

(√242)² = x² + x²

242 = 2x²

x² = 121

x = 11 cm

The equation of a line passing through the origin and parallel to the line passing through the points (8, 3) and (10, 8) is 2y - 5x = 0.

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

Let's suppose the equation of that line as the slope-intercept form is

y = mx + c

Where m is the slope while c is the y-intercept.

Now this line is parallel to a line that passes through points  (8, 3) and

(10, 8) thus meaning the slope of both lines must be the same.

So,

Slope associated with points  (8, 3) and (10, 8) ⇒

m = difference in y's coordinate / difference in x's coordinate

m = (8 - 3)/(10 - 3)

m = 5/7

So our equation will be y = (5/7)x + c

Since it is passing through the origin or (0,0) so it will satisfy the coordinate.

Therefore,

0 = (5/7)0 + c ⇒ c = 0

It means y = (5/7)x ⇒ 7y - 5x = 0 will be the equation.

Hence "The equation of a line passing through the origin and parallel to the line passing through the points (8, 3) and (10, 8) is 2y - 5x = 0".

x = y → (1)

6x + 5y = - 22 → (2)

substitute x = y into (2)

6y + 5y = - 22

The domain of the quadratic equation is all non-negative real numbers.

The picture indicates the case of the launch of an object from the top of a building. The height of the object (f(x)), in feet, as a function of time, (x), in seconds. Both height and time are represented by non-negative real numbers and hence the following solutions do not make sense in the context of problem:

Now we proceed to fill the blanks in the four paragraphs:

f(- 2) = 0, meaning that - 2 second after the object was launched, the object was 0 feet above the ground. This interpretation does NOT make sense in the context of the problem.

f(0.5) = 100, meaning that 0.5 seconds after the object was launched, the object was 100 feet above the ground. This interpretation make sense in the context of the problem.

f(6) = - 224, meaning that 6 seconds after the object was launched, the object was - 224 feet above the ground. This interpretation does NOT make sense in the context of the problem.

Answer:

A) x = m - n - p

Step-by-step explanation:

m - x = n + p

subtract m from both sides

m - x (- m) = n + p (- m)

m cancels out on the left and stays on the right

- x = n + p - m

divide by -1 because this is the constant in front of x

visualize as -1*x if it helps (anything multiplied by 1 is that number)

(- x / -1) = (n / -1) + (p/ -1) - (m/ -1)

the positives become negative and the negatives become positive

x = -n - p + m or x = m - n - p
