Answer:

  x = ±√((d -c)/a)

Step-by-step explanation:

The usual "solve for ..." approach works fine in this case.

  ax^2 +c = d

  ax^2 = d - c . . . . . subtract c

  x^2 = (d -c)/a . . . . divide by a

  x = ±√((d -c)/a) . . . take the square root

When there are numbers, a graphical solution could work. It depends on whether an exact or approximate solution is required.

Comment on "solve for ..."

When solving an equation for a specific variable, it is worthwhile to consider the Order of Operations. Look at what has been done to the variable, then undo those operations in reverse order. Here, the variable has been squared, the product multiplied by 'a', that product added to c. So, the "undo" consists of subtracting 'c', dividing by 'a', and taking the square root.

Answer:

m∠T = 79°

m∠V = 14°

Step-by-step explanation:

Given

As the sum of measures of the angles is 93°.

so

m∠T + m∠V = 93°

(2x + 85)° + (5x + 29)° = 93°

Remove parentheses

[tex]2x+85+5x+29=93[/tex]

[tex]7x+114=93[/tex]

Subtract 114 from both sides

[tex]7x+114-114=93-114[/tex]

Simplify

[tex]7x=-21[/tex]

Divide both sides by 7

[tex]\frac{7x}{7}=\frac{-21}{7}[/tex]

simplify

[tex]x=-3[/tex]

Determining m∠T

m∠T = (2x + 85)°

substitute x = -3

m∠T = (2(-3) + 85)°

        = -6 + 85

        = 79°

Thus, we conclude that m∠T = 79°

Determining m∠V

m∠V = (5x + 29)°

substitute x = -3

m∠T = (5(-3) + 29)°

        = -15 + 29

        = 14°

Thus, we conclude that m∠V = 14°

VERIFICATION:

m∠T + m∠V = 93°

substitute m∠T = 79° and m∠V = 14°

79° + 14° = 93°

93° =  93°

Step-by-step explanation:

A and E

A

because x+5 = x-5

x-x = -5 -5

0 = -10

E

8 + 4f = 4(3+f)

8 + 4f = 12 + 4f

4f - 4f = 12 - 8

0 = 4

A and E it's not true

Answer:

Step-by-step explanation:

Answer: The answer is It will eventually exceed the population of Country B. The other answer is It is increasing exponentially

Step-by-step explanation:

The correct answers would be statements (C) and (D) for the given table.

An exponential function is defined as a function whose value is a constant raised to the power of an argument is called an exponential function.

The population of these two countries for the last five years is displayed in the given table. Both countries' populations are predicted to continue growing at the same rate.

The following statements can the students use in their report to accurately describe the population of Country A, as:

It will eventually exceed the population of Country B.

It is increasing exponentially.

Hence, the correct answers would be statements (C) and (D).

Answer:

B

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

V = pi r^2 h

isolate h by moving pi & r^2 to the other side.  

Move with opposite operation from multiplying which is dividing, so

h = V / (pi r^2)

Answer:

1. y ≥ 100

2. y ≤ 300

3. y ≥ 20000

4. 2y ≥ 80

5. 2y ≤ 90

Step-by-step explanation:

Let y be the variable.

1. The discount is not less than 100.

If the discount (i.e y) is not less than 100, it means it is either 100 or greater than 100.

This can be written as:

y ≥ 100

2. The cost of the book is at most 300.

This implies that the cost of the book (i.e y) is either 300 or lesser.

This can be written as:

y ≤ 300

3. His monthly income is at least 20000. This simply means that his monthly income (i.e y) is 20000 or greater than 20000.

This can be written as:

y ≥ 20000

4. Twice the number is at least 80.

Let the number be y.

Twice the number y can be written as:

2y

But twice the number is at least 80.

This means that twice the number is 80 or greater than 80. This can be written as:

2y ≥ 80

5. Twice the measure of the acute angle is not more than 90 degree.

Let the angle be y.

Twice the angle can be written as:

2y

But twice the measure of the angle is not more than 90 degree. This implies that twice the angle is 90 or lesser than 90. This can be written as:

2y ≤ 90

Step-by-step explanation:

Answer:

r = 10

Step-by-step explanation:

The equation of a circle centred at the origin is

x² + y² = r² ( r is the radius )

x² + y² = 100 ← is a circle centred at the origin with

r² = 100 ( take the square root of both sides )

r = [tex]\sqrt{100}[/tex] = 10

Answer:

The solution is:

[tex]-\frac{1}{2}x\ge \:4\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \:-8\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:-8]\end{bmatrix}[/tex]

The number line graph of the solution is also attached below.

From the graph, it is clear that the 2nd number line represents the solution set for the inequality.

Step-by-step explanation:

Given the inequality

[tex]-\frac{1}{2}x\ge 4[/tex]

Let us solve the inequality

[tex]-\frac{1}{2}x\ge 4[/tex]

Multiply both sides by -1 (reverse the inequality)

[tex]\left(-\frac{1}{2}x\right)\left(-1\right)\le \:4\left(-1\right)[/tex]

Simplify

[tex]\frac{1}{2}x\le \:-4[/tex]

Multiply both sides by 2

[tex]2\cdot \frac{1}{2}x\le \:2\left(-4\right)[/tex]

Simplify

[tex]x\le \:-8[/tex]

Thus, the solution is:

[tex]-\frac{1}{2}x\ge \:4\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \:-8\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:-8]\end{bmatrix}[/tex]

The number line graph of the solution is also attached below.

From the graph, it is clear that the 2nd number line represents the solution set for the inequality.

Answer:

The sale price was $244.9.

Step-by-step explanation:

With the information provided, you can calculate the sale price by finding the 21% of the sale price and then, subtracting that amount from the sale price:

$310*21%=$65.1

$310-$65.1=$244.9

According to this, the answer is that the sale price was $244.9.
