Answer:
By a small online search, i found that the actual question seems to be:
"Stephanie uses a ride service to get to different places in her city. If Stephanie uses Uber the service charges $5.00 plus 1.50 per mile . If Stephanie uses lift the service charges $2.00 per mile. Let m represent the number of miles traveled. Which of the following statements are true . Select all that apply"
The statements are not provided, so i will answer it in a general way.
We have two different equations:
1) a fixed amount of $5.00 plus $1.50 for each mile, m.
This is a linear equation:
y1 = $1.50*m + $5.00
2) No fixed amount, only $2.00 for each mile, m.
y2 = $2.00*m
Now, the things we can see are which service will be cheaper as a function of m.
To see this, we can see the difference between y1 and y2.
When the difference is negative, this means that y1 is cheaper.
When the difference is positive this means that y2 is cheaper.
When the difference is zero, both services charge the same.
D = y1 - y2 = $1.50*m + $5.00 - $2.00*m
= (-$0.50)*m + $5.00
First let's find when it is zero.
0 = (-$0.50)*m + $5.00
5.00/0.5 = m = 10
So for 10 miles, both services charge the same.
As the coefficient that multipies m is negative, if we have m > 10, then the difference will be negative.
This means that for m > 10, y1 is cheaper.
Then for m < 10, y2 is cheaper.
y2 – x; use x = 7, and y = 7
Step-by-step explanation:
[tex] {7}^{2} - 7 = 49 - 7 = 42 \\ so \: required \: answer \: is \: 42[/tex]

- 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
-4x + 9(1) = 9
-4x + 9 = 9
-4x = -9 + 9
-4x = 0
x = 0/-4
x = 0

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

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%
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
