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) ".

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:

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

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

Boys = b

Girls = g

Equations as per given:

b + g = 180b = g + 32

Substitute b:

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

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

multiplying two complex numbers involves ______.

a. scaling
b. dilation
c. change in magnitude
d. scaling and rotation

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.

So probably A. I sorry, but I need more information. Hope this helps
