Answers

Answer:

Multiplying a complex number by a real number

(x + yi) u = xu + yu i. In other words, you just multiply both parts of the complex number by the real number. For example, 2 times 3 + i is just 6 + 2i. Geometrically, when you double a complex number, just double the distance from the origin, 0.

binomial methods

Complex numbers use binomial methods of multiplication because unlike real numbers, imaginary numbers have two components.

Choose the expression that is equivalent to both −xy and x−y.

Answers

Answer:

x-y

Step-by-step explanation:

The expression which is equivalent to both -x/y and x/(-y) is the -1(x/y)  thus option (C) will be correct.

What is an expression?

A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.

An expression is a mathematical proof of the equality of two mathematical expressions.

As per the given expression,

-x/y and x/(-y)

If an expression is equivalent to both then both also must be the same.

Therefore, -x/y = x/(-y)

[(-1)x]/y = x/[(-1)y]

(-1)[x/y]= -x/y

Thus, -x/y = x/(-y) = (-1)[x/y]

Hence "The expression which is equivalent to both -x/y and x/(-y) is the -1(x/y) ".

2(4p +1) = 2(2p-5)

Answers

Answer:

p = -3

Step-by-step explanation:

2(4p + 1) = 2(2p - 5)

8p + 2 = 4p - 10

Subtract 4p from both sides.

8p - 4p = 4p

4p + 2 = -10

4p + 2 - 2 = 10 - 2

4p = -12

4p ÷ 4 = p

-12 ÷ 4 = -3.

Hence, p = -3.

Hope this helped.

Answer:

[tex]p=-3[/tex]

Step-by-step explanation:

--------------------------------------

[tex]2\left(4p+1\right)=2\left(2p-5\right)[/tex]

Expand:- [tex]2\left(4p+1\right)[/tex]

[tex]=8p+2[/tex]

Expand:- [tex]2(2p-5)[/tex]

[tex]=4p-10[/tex]

-------------------------------------

[tex]8p+2=4p-10[/tex]

→ Subtract 2 from both sides:

[tex]8p+2-2=4p-10-2[/tex]

[tex]8p=4p-12[/tex]

→ Subtract 4p from both sides:

[tex]8p-4p=4p-12-4p[/tex]

[tex]4p=-12[/tex]

→ Divide both sides by 4:

The graph of linear function f passes through the point (3, 2) and has a slope of 2. What is the zero of f?

Answers

Considering the definition of a line and zero of a linear function, the zero of the linear function that passes through the point (3, 2) and has a slope of 2 is 2.

Linear equation

A linear equation o line can be expressed in the form y = mx + b

where

x and y are coordinates of a point.m is the slope.b is the ordinate to the origin and represents the coordinate of the point where the line crosses the y axis.

Zeros of a function

The points where a linear function crosses the axis of the independent term (x) represent the so-called zeros of the function.

That is, zeros of the function are those values ​​of x for which the expression is equal to 0.

Line in this case

In this case, you know:

The line has a slope of 2.The line passes through the point (3, 2).

Substituting the value of the slope m, you get:

y= 2x +b

Replacing the value of the point in the  previous expression, the value of the ordinate to the origin b can be obtained:

2= 2×3 + b

2= 6 + b

2-6= b

-4= b

The equation of the line that passes through the point (3, 2) and has a slope of 2 is y= 2x -4.

The zero of the function is calculated as:

0= 2x -4

Solving:

0 + 4= 2x

4= 2x

4÷2= x

2=x

Finally, the zero of the linear function is 2.

3)There were 180 students in attendance at the dance. If there were 32 more boys than girls at the dance, how many girls and boys were at the dance?

4)There were 293 tickets sold for a concert. Tickets purchased before the concert were $10, but tickets purchased at the gate were $15. The total ticket sales were $3495. How many people bought tickets before the concert, and how many purchased tickets at the gate?

Answers

Answer:

1. 7 Nickels, 13 Dimes

2. 30 Nickels, 15 Quarters

3. 74 Girls, 106 Boys

4. 180 tickets bought before and 113 bought at the gate

Step-by-step explanation:

Answer:

1) 7 nickels and 13 dimes2) 15 quarters and 30 nickels3) 74 girls and 106 boys4) 180 tickets bought before, 113 - at the gate

Step-by-step explanation:

1)

Nickel: n = 5c, Dime: d = 10c

Equations as per given:

d = n + 65n + 10d = 165c

Substitute d:

5n + 10(n+6) = 1655n + 10n + 60 = 16515n = 105n = 105/15 = 7d = n+ 6 = 7 + 6 = 13

2)

Nickels: n = 5c, Quarters: q = 25c

Equations as per given:

n = q + 155n + 25q = 525c

Substitute n:

5(q + 15) + 25q = 5255q + 75 + 25q = 52530q = 450q = 15n = q + 15 = 15 + 15 = 30

3)

Boys = b

Girls = g

Equations as per given:

b + g = 180b = g + 32

Substitute b:

g + 32 + g = 1802g = 148g = 74b = 74 + 32 = 106

4)

Tickets purchased at the gate: g = $15

Tickets purchased before the concert: b = $10

Equations as per given:

b + g = 293 ⇒ b = 293 - g10b + 15g = 3495

Substitute b:

10(293 - g) + 15g = 34952930 - 10g + 15g = 34955g = 3495 - 29305g = 565g = 565/5g = 113b = 293 - g = 293 - 113 = 180
