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) ".

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 = 180In the right triangle shown, m∠G=45° and HI = 7

multiplying two complex numbers involves ______.
a. scaling
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.
So probably A. I sorry, but I need more information. Hope this helps

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.

2. Solve the equation below. please show your work!! :))
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:
[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:
[tex]\frac{4p}{4}=\frac{-12}{4}[/tex]
[tex]p=-3[/tex]
