Answer:

No! {-2, 1} is not a solution set to the given equation.

Step-by-step explanation:

The statement  X squared take away 2X Takeaway three equals X take away one can be written in mathematical terms as follows:

X² - 2X - 3 = X - 1

⇒ X² - 2X - 3 - X + 1 =0

⇒ X² - 3X - 2 = 0

Now, substitute x= -2 and see if the equation is satisfied.

⇒ (-2)² -3(-2) - 2 = 4 + 6 - 2

= 8 ≠ 0

So, -2 is not a solution to the equation.

Now, check for x = 1.

⇒ (1)² - 3(1) - 2 = 1 - 3 - 2

= -4 ≠ 0

⇒ x = 1 is not a solution as well.

Final answer:

To solve both 3/8 x 4 and 3/6 x 4, we multiply the numerator by 4 and simplify the resulting fraction if necessary, resulting in 1.5 for the first expression and 2 for the second.

Explanation:

To solve the problem 3/8 x 4 and 3/6 x 4, we need to perform multiplication of a fraction by a whole number. For the first part, we multiply the numerator (3) by the whole number (4) and keep the denominator (8) to get 12/8, which simplifies to 1 1/2 or 1.5. For the second part, we simplify the fraction 3/6 to 1/2 since both the numerator and denominator can be divided by 3. Then, again, we multiply the numerator (1) by the whole number (4) and keep the denominator (2), resulting in 4/2, which simplifies to 2.

Step-by-step explanation:

We need to find the false statement.

The first one is true (m<RPS=m<WPR because RU⊥SW).

The second statement is true because the two angles make a linear pair and are supplementary.

The third one is false because we only know that the angle pair is complimentary. Their measures are not equal.

Answer:

π(6²)

Step-by-step explanation:

The base of the cone is a circle with area (A) calculated as

A = πr² ← r is the radius

Here diameter = 12 , hence r = 12 ÷ 2 = 6, thus

A = π(6²)

Answer:

The answer is A

Step-by-step explanation:

The answer is A because a circle is a circle and it doesn't have any sides and it's a bunch of points that are the same distance from each other creating a circle like object.

Hope this helps :))

Option A is the correct answer that is a collection of all points in a plane that are the same distance from a given point.

The circle is defined as the locus of the point traces around a fixed point called the centre and is equidistant from the outer trace.

The circle is also defined as the collection of all points in a plane that are the same distance from a given point.

Therefore Option A is the correct answer that is a collection of all points in a plane that are the same distance from a given point.

The area of the rectangle will be 12b⁶ + 6b³ – 18b².

Let H be the height and W be the width of the rectangle. The area of the rectangle is the product of height and width.

Then the area of the rectangle will be

Area of the rectangle = H × W square units

A rectangle has a height of 3b² and a width of 4b⁴ + 2b – 6.

Then the area of the rectangle will be

Substitute H = 3b² and W = 4b⁴ + 2b – 6. Then the area of the rectangle will be

Area of the rectangle = 3b² x (4b⁴ + 2b – 6)

Simplify the equation, we have

Area of the rectangle = 3b² · 4b⁴ + 3b² · 2b – 3b² · 6

Area of the rectangle = 12b⁶ + 6b³ – 18b²

Thus, the area of the rectangle will be 12b⁶ + 6b³ – 18b².

Step-by-step explanation:

Answer:

C. $945

Step-by-step explanation:

Cost of 1 cellular bill = (number of text msgs per day) x (cost per text msg) x (number of days in billing period)

in this case, it is given that :

cost per text msg = $0.89

number of texts per day = 22 or 23

billing cycle = 6 weeks = 6 x 7 = 42 days

hence,

Cost of 1 cellular bill = (22 or 23) x $0.89 x 42 days

if she sends 22 messages,

Cost of 1 cellular bill = (22) x $0.89 x 42 days= $822.36

if she sends 23 messages,

Cost of 1 cellular bill = (2) x $0.89 x 42 days= $859.74

if we compare thse 2 numbers that we have calculated with the choices, the closest match would be C. $945. The rest are just too far away in comparison.

Answer:

120.35

Step-by-step explanation:

De tanque lleno de agua,se utilizan las dos quintas partes y luego los tres cuartos del resto. Si aún quedan 240 litros ¿cuántos litros tiene?

2/5- 3/4=-0.35

tienes 120 galones más el 0.35

120+0.35=120.35

que tengas un buen día!!!!!!!!!!!!!

The initial amount of water in the tank was 1600 liters.

Let's denote the initial amount of water in the tank as W.

First, two-fifths of the water are used, leaving [tex]\(\frac{3}{5}\)[/tex] of the water remaining.

[tex]\[\text{Remaining amount} = \frac{3}{5} \times W\][/tex]

Then, three-quarters of the remaining water are used, leaving \(\frac{1}{4}\) of the remaining water.

[tex]\[\text{Final amount} = \frac{1}{4} \times \left(\frac{3}{5} \times W\right)\][/tex]

According to the problem, the final amount is 240 liters:

[tex]\[\frac{1}{4} \times \left(\frac{3}{5} \times W\right) = 240\][/tex]

Now, solve for W:

[tex]\[\frac{3}{5} \times W = 240 \times 4\][/tex]

[tex]\[\frac{3}{5} \times W = 960\][/tex]

[tex]\[W = \frac{960 \times 5}{3}\][/tex]

[tex]\[W = 1600\][/tex]

So, the initial amount of water in the tank was 1600 liters.

Answer:

The speed of the boat in still water is 30 mph, and the speed of the current is 6 mph.

Step-by-step explanation:

Let's say b is the speed of the boat in still water, and c is the speed of the current.

Distance = rate × time

Going downstream:

504 = (b + c) × 14

36 = b + c

Going upstream:

504 = (b − c) × 21

24 = b − c

Two equations, two variables.  Solve with substitution or elimination.  To use elimination, add the equations together.

60 = 2b

b = 30

Plug into any equation to find c.

36 = b + c

36 = 30 + c

c = 6

The speed of the boat in still water is 30 mph, and the speed of the current is 6 mph.

The speed of the boat in still water will be 30 miles per hour and the speed of the current will be 6 miles per hour.

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

Let the speed of the boat in still water be x and the speed of water be y.

A boat traveled 504 miles downstream and back. The trip downstream took 14 hours. Then the equation will be

x + y = 504 / 14

x + y = 36      ...1

The trip back took 21 hours. Then the equation will be

x - y = 504 / 21

x - y = 24       ...2

Add equations 1 and 2, then the value of x will be

2x = 36 + 24

2x = 60

x = 30 miles per hour

Then the value of y will be

30 - y = 24

y = 6 miles per hour

The speed of the boat in still water will be 30 miles per hour and the speed of the current will be 6 miles per hour.

Commission earned by William is $ 45.84

Given that,

William makes a commission of 6% percent on everything he sells

He sells a computer for $764.00

To find: Commission amount of William

Given that he makes a commission of 6 % on everything he sells. So he has received a commission of 6 % of $ 764.00

Commission amount of William = 6 % of $ 764.00

a % of b can be written in fraction as [tex]\frac{a}{100} \times b[/tex]

[tex]6 \% \text { of } 764=\frac{6}{100} \times 764=0.06 \times 764=45.84[/tex]

The first five terms of sequence is 4.5, -27, 162, -972, 5832

Solution:

Given that we have to find first five terms of recursive sequence

Given sequence is:

[tex]a_n = -6a_{n - 1}[/tex]

To find first five terms, substitute n = 2, 3, 4, 5

First term is given = [tex]a_1[/tex] = 4.5

Find second term:

Substitute n = 2 in given sequence

[tex]a_2 = -6a_{2 - 1}\\\\a_2 = -6a_1\\\\a_2 = -6(4.5) = -27[/tex]

Thus second term of given sequence is -27

Find third term:

Substitute n = 3 in given sequence

[tex]a_3 = -6a_{3-1}\\\\a_3 = -6a_2\\\\a_3 = -6(-27) = 162[/tex]

Thus third term of given sequence is 162

Find fourth term:

Substitute n = 4 in given sequence

[tex]a_4 = -6a_{4-1}\\\\a_4 = -6a_3\\\\a_4 = -6(162) = -972[/tex]

Thus fourth term of given sequence is -972

Find fifth term:

Substitute n = 5 in given sequence

[tex]a_5 = -6a_{5-1}\\\\a_5 = -6a_4\\\\a_5 = -6(-972) = 5832[/tex]

Thus the first five terms of sequence is 4.5, -27, 162, -972, 5832

Answer:

x=-7

Step-by-step explanation:

The value of x if,  Lines 1 and 2 are parallel, LINE 1: (-2,5) and (0,0) LINE 2: (x,12) and (-3,2) is -7.

An object having an endless length and no width, depth, or curvature is called a line. Since lines can exist in two, three, or higher-dimensional environments, they are one-dimensional things.

Given:

Line 1 and line 2 are parallel,

The coordinates of lines are given as,

LINE 1: (-2, 5) and (0, 0) LINE 2: (x, 12) and (-3, 2)

As we know that the slope of the parallel lines is equal,

Calculate the slope of Line 1 as shown below,

Slope = 0 - 5 / 0 - (-2)

Slope = -5 / 2

Thus, for the second line,

The slope of Line 2 = (2 - 12) / (-3 - x)

-5 / 2 = -10 / -3 - x

-5(-3 - x) = -20

15 + 5x = -20

5x = -20 - 15

x = -35 / 5

x = -7
