Answer:

solution: (9, 3) ,   x = 9, y = 3

Step-by-step explanation:

Negative 4 x + 6 y = negative 18 and y = negative 2 x + 21

convert to algebra.

- 4x + 6y = -18 ;

y = -2x + 21;

let us solve this with elimination

change -4x + 6y = -18  to  -2x + 3y = -9

get:  -2x  + 3y = -9

and  2x + y = 21

add.

-2x + 2x + 3y + y = -9 + 21

4y = 12

y = 3

2x + (3 ) = 21

2x = 18

x = 9

Answer: -16

Step-by-step explanation:

Let the number be y

Four times a number minus twenty-one can be written as:

(4 × y) - 21 = 4y - 21

Six times the number plus eleven can be written as:

(6 × y) + 11 = 6y + 11

Combining both equations will give:

4y - 21 = 6y + 11

4y - 6y = 11 + 21

-2y = 32

y = 32/-2

y = -16

The number is -16

Answer:

A. 56.52 cm

Step-by-step explanation:

Formula:

Circumfrence= 2πr

r(radius) = 9 cm

C = 2πr

C = 2 x 3.14 x 9 cm

C = 6.28 x 9 cm

C = 56.52 cm

Circumfrence is 56.52 cm

The circumference of the circle is 56.52cm (A)

To calculate the circumference of a circle, the formula is Circumference (C) = 2πr.

Where;

radius (r) = 9cm

π = 3.14

Substitute the values into the formula.

C = 2 x 3.14 x 9

C = 56.52 cm

Therefore, the circumference of the circle is 56.52cm (A)

Answer:

The product of the real and complex number given is -10+40i

Step-by-step explanation:

The general form of a complex number is expressed as z = x+iy where

x is the real part and y is the imaginary part.

Given a complex and a real value as shown

z1 = −2+8i and z2 = 5+i0

Taking their product;

z1z2 = (−2+8i)(5+i0)

z1z2 = -10+0+40i+0

z1z2 = -10+40i

According to the product of the complex numbers, the resulting real part is -10 and the complex part is 40.

The representation on the complex plane is as shown in the attachment.

The complex number −2+8i has modulus of (1. 2√17)

When −2+8i is multiplied by 5, the modulus of the product is (2. 10√17)

Multiplying a complex number by a real number results in a scalar of the complex number. The quadrant location of the complex number and its product with (3. a positive real number) are the same.

Answer:

The probability of choosing tiles which sum is 12 is 1/21

Step-by-step explanation:

The numbers we have is 1.2,3,4,5,6 and 7

The sum we are looking at is 12. The only sum that can give us this sum is the addition of 7 and 5

There are only two ways we can make this selection if order matters.

Either we pick 5 first then 7 second or 7 first and 5 second

The probability of picking a 5 first will be 1/7, since it is without replacement , the probability of picking a 7 next will be 1/6

The joint probability here would thus be 1/7 * 1/6 = 1/42

In the other second case where we are picking a 7 first and a 5 second, the probability here will be the same as first just that we reversed the other. Hence, the probability here is also 1/42

Now, the probability of either of the two orders happening will be 1/42 + 1/42 = 2/42 = 1/21

Final answer:

The probability of choosing tiles whose sum is 12 is 1/49.

Explanation:

Probability of choosing tiles whose sum is 12:

Number of favorable outcomes: 1 (getting two tiles that sum up to 12, which is 6+6)Total number of possible outcomes: 7*7 = 49 (as there are 7 choices for each tile)Probability = Number of favorable outcomes / Total number of possible outcomes = 1/49

Answer:

$1,467.20

Step-by-step explanation:

Adjusted monthly income is the gross income minus any payments made every month. 5600 - 360 = 5240. To get 28% of her adjusted income multiply 5240 X.28 =1467.20

To calculate 28% of $5600, multiply 5600 by 0.28. The result is $1568, which is 28% of Adeva's gross monthly income.

The issue is figuring out 28% of Adeeva's gross monthly salary, which is fixed at $5600. The calculation is simple to perform using the (Amount/Total) x 100 rule for percentage calculations. The decimal equivalent of 28% is 0.28, so multiply $5600 by that number to get 28%. The computation yields a value of $1568. Therefore, $1568 or 28% of Adeeva's gross monthly revenue. By analyzing particular sections of overall profits, this technique demonstrates a fundamental use of percentages, enabling accurate financial computations and planning.

Answer: Option C.

Step-by-step explanation:

We have functions of r(θ)

In our graph, we can see that the minimum value of r is when θ = 0°, and the maximum value is when θ = 180°.

We also know that the graph is in the square (-5, 5)x(-5, 5) and you can see that the maximum radius is almost less than 5.

Then let's analyze the options:

A) r = 3 - 2*cos(θ)

the maximum is at the right angle, but the maximum is:

r = 3 -2*(-1) = 5, so this maximum value is bigger than the one in the graph.

B) r = 3 - sin(θ)

For the sin functions, the maximum and minimum do not correspond with the values i write earlier, so we can discard this option.

C) r = 3 - cos(θ)

The maximum is: r = 3 - (-1) = 4, so this may be the correct answer.

the minimum is r = 3 - 1 = 2,

this is a possible equation for our circle.

D) r = 2 - 2*cos(θ)

Here, when θ = 0, we have: r = 2 - 2*1 = 0, but in the graph we can see that the radius is not 0 when θ = 0, so we can discard this option.

So the only option that makes sense is option C.

The answer is D. x2 + 6x + 9 i just took the assignment

Final answer:

The expression that represents the area of a square plaza with side length 2x + 3 is x^2 + 6x + 9.

Explanation:

The question is asking to determine the expression that represents the area of a square plaza. The formula to calculate the area of a square is the length of one side squared (s2). If the side length is represented by the expression 2x + 3, then the area will be (2x + 3)2. When this binomial is squared, it follows the formula (a + b)2 = a2 + 2ab + b2, which leads to (2x)2 + 2(2x)(3) + (3)2 = 4x2 + 12x + 9. So, the correct expression representing the area of the plaza is x2 + 6x + 9.

Answer:

(5/3,5)

Step-by-step explanation:

The solution to the system of equations y = 13x - 1 and y = 5 is (6/13, 5).

To find the solution to the system of equations y = 13x - 1 and y = 5, we can substitute the second equation directly into the first one. Since both equations equal y, they must equal each other, thus:

13x - 1 = 5.

We can then solve for x:

Add 1 to both sides: 13x = 6

Divide both sides by 13: x = 6/13

Having determined the value of x to be 6/13, we can substitute this back into either equation to find y. Using the simpler one, y = 5.

Thus, the solution to the system of equations is (6/13, 5).

We are gonna use "dollars" instead of "soles.

According to the problem, tickets cost $30 for adults and $20 for children.

Last Saturday assisted 248 people which gave a total of $5930.

To know the number of adults and children were there, we need to defined a system of equations.

[tex]x+y=248\\30x+20y=5930[/tex]

Where [tex]x[/tex] represents adults and [tex]y[/tex] represents children.

First, we multiply the first equation by -20

[tex]-20x-20y=-4960[/tex]

Then, we sum this equation with the second one

[tex]10x=970\\x=97[/tex]

There were 97 adults.

Now, we use this value to find the other one

[tex]x+y=248\\97+y=248\\y=248-97\\y=151[/tex]

There were 151 children.

Therefore, 97 adults and 151 children assisted to that show.
