Answer:
y = x
Step-by-step explanation:
The slopes of parallel lines are the same, so we know the equation will be ...
y = x + constant
We can find the constant by using the given point's values for x and y:
2 = 2 + constant
Obviously, the constant is zero.
The equation of the parallel line through (2, 2) is y = x.

7(6-2A)=5(-3A+1) help need steps and answer!
Answer:
A = -37
Step-by-step explanation:
7(6-2A)=5(-3A+1)
Distribute
42 - 14A = -15A +5
Add 15A to each side
42 - 14A +15A= -15A+15A +5
42+A = 5
Subtract 42 from each side
42+A -42 = 5-42
A = -37

Answer: (-11, -5.5)
Step-by-step explanation:
Use Midpoint formula: [tex](\frac{x1+x2}{2} ,\frac{y1+y2}{2} )[/tex]
Midpoint M= (-9, -3)
(x1, y1)=(-7, -0.5)
-------------------------------------------------
[tex]\frac{x1+x2}{2}[/tex]=-9
-7+x2=-18
x2=-11
---------------------------------------------
[tex]\frac{y1+y2}{2}[/tex]=-3
-0.5+y2=-6
y2=-5.5
(-11, -5.5)

what are the coefficients of 8+5x-y
Answer:The coefficients are the numbers that multiply the variables or letters. Thus in 5x + y - 7, 5 is a coefficient. It is the coefficient in the term 5x. Also the term y can be thought of as 1y so 1 is also a coefficient.A number used to multiply a variable. Example: 6z means 6 times z, and "z" is a variable, so 6 is a coefficient. Variables with no number have a coefficient of 1. ... Example: In ax2 + bx + c, "x" is a variable, and "a" and "b" are coefficients.First of all, coefficent means the number standing in front of a variable.
So, according to the expression, 2 - 5x - 4 + 8, the coefficient is -5.
Why? because it stands in front of the variable.
Step-by-step explanation:
The following graph describes function 1, and the equation below it describes function 2:
Function 1
graph of function f of x equals negative x squared plus 8 multiplied by x minus 15
Function 2
f(x) = −x2 + 2x − 3
Function ____ has the larger maximum.
(Put 1 or 2 in the blank space)
Answer:
Answer:
Function 1 written in vertex form is f(x) = -x^2 + 8x - 15 = -(x^2 - 8x + 15) = -(x^2 - 8x + 16 + 15 - 16) = -(x - 4)^2 - (-1) = -(x - 4)^2 + 1
Therefore, vertex = (4, 1)
Function 2 written in vertex form is f(x) = -x^2 + 4x + 1 = -(x^2 - 4x - 1) = -(x^2 - 4x + 4 - 1 - 4) = -(x - 2)^2 - (-5) = -(x - 2)^2 + 5
Therefore vertex = (2, 5)
Function 1 has a maximum at y = 1 and function 2 has a maximum at y = 5. Therefore, function 2 has a larger maximum.

The value of β is:
A)60º
B)45º
C)90º
D)30º
E)75º
Answer:
A
Step-by-step explanation:
To solve this problem, it is best to identify the sides (opposite, adjacent, hypotenuse) in terms of β. Since the adjacent side of β is 3 and the hypotenuse is 6, we know that cos(β) = 3/6 = 1/2. That means β = 60º, which is choice A.

Answer:
d ⇒ di^(21-22) = -di, facing right from where it was; order doesn't matter
Step-by-step explanation:
For direction defined as 1, i, -1, -i, a left turn is accomplished by multiplying by i. Then "L" left turns will be multiplication by i^L.
A right turn is equivalent to multiplication by -i, so R right turns will be multiplication by (-i)^R.
We know that turning left and turning right are inverse operations of each other, so we can also write a right turn as multiplication by i^(-1). Then R right turns will be equivalent to multiplication by i^(-R).
We know from the commutative and associative laws of multiplication that the order does not matter. So, L left turns and R right turns will be equivalent to multiplication by ...
(i^L)(i^-R) = i^(L -R)
Hence 21 left turns and 22 right turns is equivalent to a turn of ...
i^(21-22) = i^-1 . . . . one right turn
From an initial facing direction of 'd', the final facing direction after these 43 turns is -di.
A printer prints 4 photos each minute. Let P be the number of photos printed in M minutes. Write an equation relating P to M . Then graph your equation using the axes below. Please include graph!
Answer:
sorry i accidently put stuff in the comments
equation:
T=4M
graph: y=4x (pic is included)
The equation relating P to M is P = 4M and the graph will be a linear graph that passes through the origin.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that:
A printer prints 4 photos each minute. Let P be the number of photos printed in M minutes. Write an equation relating P to M.
P = The number of photos printed in M minutes
M = The number of minutes.
P = 4M
Because the printer prints 4 photos each minute.
The graph will be a linear graph that passes through the origin.
Thus, the equation relating P to M is P = 4M and the graph will be a linear graph that passes through the origin.

Samantha is wall papering her bedroom and wants to make sure that she bought enough wall paper. Each wall in her room measures 10 feet by 11 feet. How many rolls of wall paper will Samantha need if each roll covers a total of 25 square feet.
Answer:
4.4 rolls of wallpaper
Step-by-step explanation:
Dimensions of Samantha's room= 10 feet by 11 feet
Length= 11 feet
Width= 10 feet
Area of Samantha's room= Length × width
= 11 feet × 10 feet
= 110 square feet
Each roll covers a total of 25 square feet
Total rolls of wallpaper = Area of the room / Area covered by each roll
=110 square feet / 25 square feet
= 4 10/25
= 4 2/5
= 4.4 rolls
a(x+b)=g+3f
solve for x
Answer:
[tex]x = (\frac{g + 3f}{a}) - b[/tex]
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
Note that PEMDAS =
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction
& is the order of operation.
First, divide a from both sides:
[tex]a(x + b) = g + 3f[/tex]
[tex]\frac{a(x + b)}{a} = \frac{g + 3f}{a}[/tex]
[tex]x + b = \frac{g + 3f}{a}[/tex]
Next, subtract b from both sides to isolate the variable, x.
[tex]x + b (-b) = \frac{g + 3f}{a} (-b)[/tex]
[tex]x = (\frac{g + 3f}{a}) - b[/tex]
[tex]x = (\frac{g + 3f}{a}) - b[/tex]

Answer:
option 3
Step-by-step explanation:
Nancy decides to roll a die three times. What's the probability that she will roll all even numbers?
Answer:
1/8
Step-by-step explanation:
The probability of rolling an even number on one roll is 3/6 = 1/2. Assuming the rolls are independent, the probability of rolling an even number 3 times is ...
(1/2)(1/2)(1/2) = 1/8
The probability that Nancy rolls all even numbers in 3 rolls is 1/8.
The probability that she will roll all even numbers is 1/8.
It should be noted that there are 6 numbers in one roll of a dice. Therefore, there are 3 even numbers and 3 odd numbers.
The probability of getting even numbers in one roll will be:
= 3/6 = 1/2
The probability that she will roll all even numbers will be:
= 1/2 × 1/2 × 1/2
= 1/8

Juan proyecta alquilar un local para hacer funcionar un gimnasio cuando las normas sanitarias lo permitan. El alquiler mensual es de S/2000, ¿a cuanto equivale el impuesto que debe pagar el dueño por alquilar su local?
Answer:
Si posee una propiedad y la alquila a inquilinos, ¿cómo se gravan esos ingresos?
La respuesta es que los ingresos por alquileres se gravan como ingresos ordinarios. Si está en el tramo impositivo marginal del 22% y tiene $ 5,000 en ingresos por alquiler que declarar, pagará $ 1,100.
Sin embargo, hay más en la historia. Los propietarios de propiedades de alquiler pueden reducir sus cargas fiscales de varias formas. De hecho, una propiedad rentable en alquiler podría no mostrar ingresos, o incluso una pérdida, a efectos fiscales.
Si uno de sus inquilin os le extiende un cheque por $ 1,000 por mes para cubrir su alquiler, se trata de ingresos por alquiler.
El impuesto deducido en el que incurre el propietario depende del tramo impositivo marginal del estado del país. Si el tramo impositivo marginal es del 20%, el impuesto será 20/100 x 2000 = 400
