Choose the expression that is equivalent to both −xy and x−y.
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)
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:
6/5 = 1.2 is the answer for the question
The question is 21/400 * 21/400 * 21/400 * 21/400. We can rephrase this as 21^4/400^4 for simplicity. 21^4 = 194,481, and 400^4 = 25,600,000,000. 194,481/25,600,000,000 = 7596.91406 * 10^8
The graph of linear function f passes through the point (3, 2) and has a slope of 2. What is the zero of f?
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 equationA 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 functionThe 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 caseIn 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.

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

1) 7 nickels and 13 dimes2) 15 quarters and 30 nickels3) 74 girls and 106 boys4) 180 tickets bought before, 113 - at the gateStep-by-step explanation:
1)
Nickel: n = 5c, Dime: d = 10c
Equations as per given:
d = n + 65n + 10d = 165cSubstitute d:
5n + 10(n+6) = 1655n + 10n + 60 = 16515n = 105n = 105/15 = 7d = n+ 6 = 7 + 6 = 132)
Nickels: n = 5c, Quarters: q = 25c
Equations as per given:
n = q + 155n + 25q = 525cSubstitute n:
5(q + 15) + 25q = 5255q + 75 + 25q = 52530q = 450q = 15n = q + 15 = 15 + 15 = 303)
Boys = b
Girls = g
Equations as per given:
b + g = 180b = g + 32Substitute b:
g + 32 + g = 1802g = 148g = 74b = 74 + 32 = 1064)
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 = 3495Substitute b:
10(293 - g) + 15g = 34952930 - 10g + 15g = 34955g = 3495 - 29305g = 565g = 565/5g = 113b = 293 - g = 293 - 113 = 1801/6x + 2/3x + 4 = x + 2
