What is an equation of the line that passes through the point (−5,−1) and is parallel to the line 4x+5y=45?
Answer:
y = -4/5x - 5
Step-by-step explanation:
4x + 5y = 45
we need to write it in slope intercept form, so:
5y = -4x + 45
y = -4/5x + 45/5
y = -4/5x + 9
The line is parallel so the slope will be -4/5x, point ( -5 -1 )
y = mx + b
-1 = -4/5(-5)+b
-1 = 4 + b
-1 - 4 = b
-5 = b
y = -4/5x - 5
Felipe es encargado de un laboratorio de informática y sabe que los alumnos frecuentemente ocupan memorias USB, con el fin de apoyar a los alumnos compra 100 memorias que a precio de mayoreo le salen a $92 cada una. Felipe vende cada USB en $100 ¿cual es el porcentaje de ganancia que obtiene Felipe por la venta de cada memoria?
Explicación paso a paso:
Cantidad total de USB comprado = 100
Precio al por mayor = $ 92
Costo de 100 memorias USB = 100 * $ 92 = $ 9,200
Si vende cada memoria USB por $ 100 cada una a precio minorista, la cantidad total en 100 USB será;
100 * $ 100 = $ 10,000
% beneficio = beneficio / precio de coste * 100%
Beneficio = precio de venta - precio de costo
Beneficio = $ 10,000 - $ 9,200
Beneficio = $ 800
% de beneficio = 800/9200 * 100
% de beneficio = 800/92
% beneficio = 8,696%
De ahí que el porcentaje de beneficio que obtiene felipe por cada venta de cada recuerdo es del 8,696%

write a quadratic function in standard form with zeros 9 and -3 PLZZZZZ HELPP MEEE
Answer:
f(x)=x^2-6x-27
Step-by-step explanation:
x=9 and x-3
set the equal to zero: x-9=0 and x+3=0
x-9 and x+3 are now the factors of your equation:
you equation so far is: (x-9)(x+3)=0
next factor these together to get: f(x)=x^2+3x-9x-27
finally simplify the equation leaving you with f(x)=x^2-6x-27

The difference in the price of 2 TVs is $217.45. If one TV costs $450.50, which of the answer choices could represent the price of the other TV?
A.) $677.95
B.) $657.95
C.)$233.05
D.) $223.05
Answer:
C.
Step-by-step explanation:
450.50 - 217.45 = $233.05 :)
The cost of another TV is $677.95
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
The difference in the price of 2 TVs is $217.45.
One TV costs = $450.5
So, 450 - Another Tv Cost = 217.45
Another Tv Cost = 217.45+ 450.5
Another Tv Cost = $677.95
Hence, the cost of another TV is $677.95

- 4x + 9y = 9
-8x + 10y = 10
Answer:
y = 1, x = 0
Step-by-step explanation:
multiply -4x +9y = 9 by -2 to get 8x -18y = -18
combine the two equations to get -8y = -8
divide both sides by -8 to get y = 1
plug in 1 as the y into one of the equations and solve to get x = 0
Answer:
(0,1)
x = 0
y = 1
Step-by-step explanation:
(-4x + 9y = 9)-8
(-8x + 10y = 10)4
32x - 72y = -72
-32x + 40y = 40
-32y = -32
y= -32/-32
y=1
