Answer:

r = d(x-e)

or r = dx - de

Step-by-step explanation:

x = e + [tex]\frac{r}{d}[/tex]  subtract e from both sides.

x - e = [tex]\frac{r}{d}[/tex]  Multiply both sides by d

d(x -e) = r

Answer:(2x+1)(3x-4)

Step-by-step explanation:Factor the expression out first by getting 6x^2+3x-8x-4. From there, factor again to 3x(2x+1)-4(2x+1) to get the answer (2x+1)(3x-4)

Answer:

(3x - 4)(2x - 1)

Step-by-step explanation:

6x^2 - 5x - 4

When factoring, we want to first find the GCF. In this case, the GCF is one so we leave it as that. Next, we want to try and find the sum and the product. Additionally, we have a leading coefficient. We will multiply the leading coefficient by the last term, which is -4. (You will need to remember this to continue on later.)

x^2 - 5x - 24

Now, we can find the sum and the product. To do this, we need to list the factors of 24. (Remember negatives as well!)

24: 1 and 24, 2 and 12, 3 and 8, 4 and 6.

As -24 is also a negative, that means it will have one positive and one negative factor. This must also add up to -5.

One pair that does this is -8 and 3. They multiply together to -24 and add up to -5.

Now, since we multiplied the leading coefficient in the beginning, we must bring it back down into the parenthesis.

(6x - 8)(6x - 3)

We must divide out and try to simplify this as much as we can to match the leading coefficient. The divisors must multiply up to 6.

(6x - 8)/2 and (6x - 3)/3.   3*2 = 6

(3x - 4)(2x - 1)

An equation in slope-intercept form that represents the situation is y = 3x - 208.

Mathematically, the slope of a straight line can be calculated by using this formula;

Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope, m = (y₂ - y₁)/(x₂ - x₁)

From the information provided, we have the following points:

Points on x-axis = (103, 105).

Points on y-axis = (101, 107).

Substituting the given points into the formula, we have;

Slope, m = (107 - 101)/(105 - 103)

Slope, m = 6/2

Slope, m = 3

Mathematically, the slope-intercept form of a straight line is given by;

y = mx + c

Where:

At point (103, 101), an equation in slope-intercept form is given by:

y - y₁ = m(x - x₁)

y - 101 = 3(x - 103)

y - 101 = 3x - 309

y = 3x - 309 + 101

y = 3x - 208.

What is a standard deviation?

The standard deviation in statistics is a measure of the amount of variation or dispersion in a set of values. A low standard deviation indicates that the values are close to the set's mean, whereas a high standard deviation indicates that the values are spread out over a larger range.

Given data:

The probability that a point chosen at random lies in the shaded region is 0.28

From the question, we are to find the probability that a point chosen at random lies in the shaded region.

The shaded region is a triangle.

The probability that a point chosen at random lies in the shaded region = Area of the triangle / Area of the circle

First, we will calculate the unknown side of the triangle

Let the unknown side be x.

Then, from the Pythagorean theorem, we can write that

12² = 6² + x²

144 = 36 + x²

x² = 144 - 36

x² = 108

x = √108

x = 6√3

From formula,

Area of a triangle = 1/2 × base × height

Area of the triangle = 1/2 × 6 × 6√3

Area of the triangle = 18√3 square units

Now, we will determine the area of the circle

Area of a circle = πr²

Where r is the radius

From the given information,

Diameter of the circle = 12

But,

Radius = Diameter / 2

Therefore,

r = 12/2

r = 6

Thus,

Area of the circle = 3.14 × 6²

Area of the circle = 113.04 square units

Now,

The probability that a point chosen at random lies in the shaded region = 18√3 / 113.04

The probability that a point chosen at random lies in the shaded region = 0.2758

The probability that a point chosen at random lies in the shaded region ≈ 0.28

Hence, the probability is 0.28

Answer:6

Step-by-step explanation:

If the three sides of the triangle is (x + 5), (2x - 3), (21 - x), then the perimeter of the triangle is 23 + 2x

The perimeter of the triangle is the summation of all three sides of the triangle

Perimeter = a + b + c

= (x + 5) + (2x - 3) + (21 - x)

= 2x + 23

= 23 + 2x

Therefore, if the three sides of the triangle is (x + 5), (2x - 3), (21 - x) then the perimeter of the triangle  23 + 2x.

Any two-dimensional figure's perimeter is determined by the space surrounding it. By adding the lengths of the sides, we can determine the perimeter of any closed shape.

The inequality given by 69.50 + 5x ≤ 90 and the maximum gigabyte he can buy is 4.1.

What is inequality?

Inequalities are mathematical expressions where neither side is equal. In inequality, as opposed to equations, we compare two values. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign in between. Sometimes it can be about a "not equal to" relationship, where one thing is more than the other or less than. In mathematics, an inequality is a relationship that results in a non-equal comparison between two numbers or other mathematical expressions.

Let the number of gigabytes consumed be x,

The total cost per month will be 69.50 + 5x

accoding to the question the bill would not exceed $90.

So the inequality,

69.50 + 5x ≤ 90

Simplification for the maximum gigabyte he can buy,

5x ≤ 90 - 59.90

A table of values and an equation for C, in terms of t, representing the total cost of using a computer for t minutes at the internet cafe are as follows:

C                         t

$10.60                1

$11.20                 2

$11.80                 3

C = 0.60t + 10.

In order to write an equation for the total cost, we would assign variables to the amount of time used and the total cost of using a computer, and then translate the word problem into algebraic equation as follows:

Since the cafe has an initial charge of $10 to use a computer and an additional charge of $0.60 for every minute of use, an equation for the total cost is given by:

C = 0.60t + 10

When t = 1, we have:

Total cost, C = 0.60(1) + 10

Total cost, C = $10.60.

When t = 2, we have:

Total cost, C = 0.60(2) + 10

Total cost, C = $11.20.

When t = 3, we have:

The most petunias Ying Ying will ever purchase is 28.

Given data;

Using x as the total amount of money in her wallet and m as the price per petunia

The money remaining in the wallet after buying 2 petunias equals $6.50 according to the provided table.

Now,

6.50 = x - 2m ⇒ (I)

In addition, $5 was left in the wallet after the purchase of 8 petunias,

5 = x - 8m ⇒ (II)

Here, (I) - (II);

6.50 - 5 = x - 2m - x + 8m

Where:

Substitute a = 3 and a₆ = 17 into the formula and solve for d:

[tex]\begin{aligned}\implies a_6=3+(6-1)d&=17\\3+5d&=17\\5d&=14\\d&=2.8\end{aligned}[/tex]

Therefore, the equation for the nth term is:

[tex]\implies a_n=3+(n-1)2.8[/tex]

[tex]\implies a_n=3+2.8n-2.8[/tex]

[tex]\implies a_n=2.8n+0.2[/tex]

To find the 8th term, substitute n = 8 into the equation for the nth term:

[tex]\implies a_8=2.8(8)+0.2=22.6[/tex]

0.302 is the probability that exactly 8 people recognize the brand

This is a binomial probability distribution. We are going to use the binomial distribution formula for determining the probability of x successes:

P(X = r) = nCr . p^r  . q^n-r

Given: number of trial (n) = 10 , probability of success (p) = 0.8, X = 8

probability of failure (q) = 1 - 0.8 = 0.2

P(X = r) = nCr . p^r  . q^n-r

P(X = 8) = 10C8 × 0.8⁸ × 0.2¹⁰⁻⁸

P(X = 8) = 45 × 0.8⁸× 0.2²

P(X = 8) =  0.302

Therefore, the probability that exactly 8 people recognize the brand is 0.302
