x + y = 24
5y = x
The solution to the given system of equations is (x,y). What is the value of y?


Answers

Answer 1

Answer:

The value of y is 4.

Step-by-step explanation:

Note the system of equation:

x + y = 24

5y = x

First, plug in 5y for x in the first equation:

x + y = 24

(5y) + y = 24

Simplify. Combine like terms. Like terms are terms that have the same amount of the same variable:

(5y + y) = 24

(6y) = 24

Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Divide 6 from both sides of the equation:

(6y)/6 = (24)/6

y = 24/6 = 4

Now, plug in 4 for y in one of the given equations in the system of equation:

x + y = 24

x + (4) = 24

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 4 from both sides of the answer:

x + 4 = 24

x + 4 (-4) = 24 (-4)

x = 24 - 4

x = 20

x = 20 , y = 4

~

Check. Use the other equation. Plug in 4 for y, and 20 for x:

5y = x

5(4) = (20)

5 * 4 = 20

20 = 20 (True)

~

The value of y is 4.

What is the greater common factor of 24 and 32

Answers

Answer:

8

Step-by-step explanation:

To calculate the greatest common factor of 24 and 32, we need to factor each number (factors of 24 = 1, 2, 3, 4, 6, 8, 12, 24; factors of 32 = 1, 2, 4, 8, 16, 32) and choose the greatest factor that exactly divides both 24 and 32, i.e., 8.

Answer:

Gabrielle angles her pool cue against the edge of her pool table, as shown below. What is the measure of angle a and angle b

Answers

The relationship between angle A and angle B is supplementary angles.

∠A  = 2(5) + 40 = 50 degrees

∠B = 5 + 125 = 130 degrees

What are supplementary angles?

Supplementary angles are angles that sum up to 180 degrees. The sum of the two angles for a supplementary angles is 180 degrees .

Therefore, the relationship between angle A and angle B is supplementary angles.

Therefore,

∠A + ∠B = 180 degrees

∠A  = 2x + 40

∠B = x + 125

2x + 40 +  x + 125  = 180

2x + x + 40 + 125 = 180

3x + 165 = 180

3x = 180 - 165

3x = 15

x = 15 / 3

x = 5

Therefore,

∠A  = 2(5) + 40 = 50 degrees

∠B = 5 + 125 = 130 degrees

Answer:

Area = 6647.610055 cm^2

Circumference = 289.02652413 cm

Step-by-step explanation:

Area of Circle: Area = π*r^2

Circumference: C = 2*π*r or π*d


Area = π * 46^2 = 6647.610055

Circumference = 2*π*46 = 289.02652413

Area = 6644.24 cm^2
Circumference = 288.88 cm

Area of a circle is pi * radius squared or pi * r^2


pi = 3.14 (the problem told us this)
radius = 46 cm


plug in the numbers

A = 3.14(46)^2

(square the 46 first)

A = 3.14 * 2116

A = 6644.24 cm ^ 2


Circumference formula is

2pi* r



plug in the numbers

C = 2 * 3.14 * 46

C = 6.28 * 46

C = 288.88 cm

The missing probability for the given mutually exclusive event is 3/10

What is Mutually Exclusive Event?

Mutually exclusive events are those events that do not occur at the same time.

Here, Let P(A) be x,

         P(B) = 11/20,     P(A or B) = 17/20,    P(A and B) = 0

         By Addition theorem of Probability,

         P(A or B) = P(A) + P(B) - P(A and B)

          17/20 = x + 11/20 - 0

          x = [tex]\frac{17}{20} - \frac{11}{20}[/tex]

          x = 6/20

Explanation:

The jump from 24 to 16 is -8

The jump from 16 to 8 is also -8

Each time we need a new term, we add on -8 which is the common difference. So we'll add -8 to 0 to get 0 + (-8) = 0 - 8 = -8 as the next term.

If you wanted another term after that, then it would be -8 + (-8) = -8-8 = -16

Then the next term after that is -16+(-8) = -16-8 = -24, and so on.

If z=-1-i, find z^10 in rectangular form.

The polar form of this problem is 3cis90degrees, what’s the rectangular form?

Answers

Answer:

See below for answers and explanations

Step-by-step explanation:

Problem 1

Let [tex]z=r(\cos\theta+i\sin\theta)[/tex] be a complex number, where [tex]n[/tex] is an integer and [tex]n\geq 1[/tex]. By DeMoivre's Theorem, if [tex]z^n=r^n(\cos\theta+i\sin\theta)^n[/tex], then [tex]z^n=r^n(\cos n\theta+i\sin n\theta)[/tex].

Hence, we must first convert from rectangular to polar form:

[tex]z=-1-i\\\\r=\sqrt{a^2+b^2}\\\\r=\sqrt{(-1)^2+(-1)^2}\\\\r=\sqrt{1+1}\\\\r=\sqrt{2}[/tex]

[tex]\displaystyle \theta=\tan^{-1}\biggr(\frac{y}{x}\biggr)\\\\\theta=\tan^{-1}\biggr(\frac{-1}{-1}\biggr)\\ \\\theta=\tan^{-1}(1)\\\\\theta=45^\circ[/tex]

Therefore, the rectangular form for the complex number is [tex]z=\sqrt{2}(\cos45^\circ+i\sin45^\circ)[/tex], and now we can apply DeMoivre's Theorem to raise the complex number to the 10th power:

[tex]z=\sqrt{2}(\cos45^\circ+i\sin45^\circ)\\\\z^{10}=\sqrt{2}^{10}(\cos45^\circ+i\sin45^\circ)^{10}\\\\z^{10}=2^5(\cos10\cdot45^\circ+i\sin10\cdot45^\circ)\\\\z^{10}=32(\cos450^\circ+i\sin450^\circ)\\\\z^{10}=32(0+i)\\\\z^{10}=32i[/tex]

Therefore, [tex]z^{10}=32i[/tex] in rectangular form.

Problem 2

[tex]3\:\text{cis}\:90^\circ=3(\cos90^\circ+i\sin90^\circ)=3(0+i)=3i[/tex]

if f (1) =5 and f (n) = 5f (n-1) + 5 then find the value of f (3)

Answers

Using the given information, the value of the f(3) is 155

Determining the value of a function

From the question, we are to determine the value of f(3)

From the given information,

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

∴ f(2) = 5f(2-1) +5

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

From the given information,

f(1) = 5

Then,

f(2) = 5(5) + 5

f(2) = 25 + 5

f(2) = 30

Also,

f(3) = 5f(3-1) + 5

f(3) = 5f(2) + 5

∴ f(3) = 5(30) + 5

f(3) = 150 + 5

f(3) = 155

Hence, the value of the f(3) is 155.
