L Por el alquiler de un coche cobran 100
pesos diarios mas 0.30 centavo por
kilometro. Encuentra la ecuacion de la recta
que relacoma el costo diarlo con el número
de kilometros
y representala.Si en un dia
se ha hecho un total de 300 km, que
importe debemos abonar?
Answers
Answer:
Sabemos que el costo del alquiler es 100 pesos diarios, más 0.30 pesos por kilómetro.
Entonces, solo por alquilar el coche por un día, hay que pagar 100 pesos.
Si además lo conduces x kilómetros, tendrás que pagar x veces 0.30 pesos.
Entonces el costo diario, en pesos, será:
C(x) = 100 + 0.30*x
Para graficar esta ecuación simplemente se deben encontrar dos pares:
(x, C(x)) en un eje de coordenadas, y luego conectarlos con una línea.
Por ejemplo, si tomamos:
x = 0
C(0) = 100 + 0.30*0 = 100
entonces tenemos el par (0, 100)
si x = 10
c(10) = 100 + 0.30*10 = 100 + 3 = 103
entonces tenemos el par (10, 103)
Ahora podemos graficar esos dos puntos y conectarlos con una línea, como en el ejemplo de abajo.
b)
También queremos conocer el costo diario si se han hecho un total de 300km.
Entonces simplemente reemplazamos x por 300 en la ecuación del costo:
C(300) = 100 + 0.30*300 = 100 + 90 = 190
El costo será de 190 pesos.
El dinero total a pagar por 300 Km es de 190 pesos.
La ecuación de una recta viene dada por y = mx + c
m = pendiente
c = intersección
Así, dado que cobran 100 pesos por día más 0,30 centavos por kilómetro, podemos escribir;
y = 100 + 0,30 x
Dado también que hay un total de 300 km, ahora tenemos;
y = 100 + 0.3(300) = 190 pesos

Answer:

Step-by-step explanation:
180°- 95°= 85°
(95° is on a straight line, angles on a straight line adds up to 180° so 95° is being subtracted from 180°. Therefore the next angle in the triangle will be 85°)

Answers
Answer:
75.5
Step-by-step explanation:
In the picture, since x is an inscribed angle, it's arc(arc XO) would be twice it's measure. Therefore, arc XO in this picture would be represented by 2x and the larger arc(arc XYO) will be represented by 360-2x since it is all of the perimeter except for the portion that is the measure of arc XO.
For this picture, you would use:
[tex]\frac{arc XYO-arc XO}{2}[/tex] =29
[tex]\frac{360-2x-2x}{2}[/tex] Substitute in the measures of the arcs.
[tex]\frac{360-4x}{2}[/tex] Combine -2x with -2x to simplify the problem
180-2x=29 DIvide by 2
-2x= -151 Subtract by 180 from both 180 and 29
x= 75.5 Divide by -2. (Both numbers are - so the answer is a +)
The points (6, 9) and (0, 6) fall on a particular line. What is its equation in slope-intercept form?
Answers
Answer:
[tex]y = \frac{1}{2}x + 6[/tex]
Step-by-step explanation:
[tex]Let \ (x _1 y _ 1 ) = ( 6 , 9 ) \ and \ (x _ 2 , y _ 2 ) \ = ( 0 , 6 )\\\\[/tex]
Step 1 : Find slope, m
[tex]slope, m = \frac{y _ 2 - y _ 1}{x_ 2 - x_ 1 } = \frac{6 - 9}{0 - 6 } = \frac{-3}{-6} = \frac{1}{2}[/tex]
Step 2 : Find the equation
[tex](y - y _ 1 ) = m ( x - x_ 1) \\\\( y - 9 ) = \frac{1}{2} (x - 6 ) \\\\y = \frac{1}{2}x - 3 + 9 \\\\y = \frac{1}{2}x + 6[/tex]
Answer:
y = 1/2x + 6
Step-by-step explanation:
y = mx + b is the formula. m is the slope and to calculate that you use the slope formula y2 - y1/ x2 - x1.
(6, 9) is the first coordinate so 6 is x1 and 9 is y1. Similarly in (0, 6), x2 is 0 and y2 is 6. Now if we put that into the slope formula it would look something like this: 6-9/0-6. that comes to -3/-6. simplify and cancel out the negatives and you get 1/2 which is the m ( slope).
The b is the y-intercept, which is the y value for where the x is 0. In this question, they already give you the coordinate where x is 0. (0, 6). x is 0 and y is 6. therefore the b (y-intercept) is 6.
Put all of this into y =mx +b, and you get y= 1/2x + 6.
If you want to make sure you did it right, just plug in one of the coordinates into this equation. Let's use (6, 9).
9 = 1/2 (6) + 6
9 = 3 + 6
9 = 9. It works out, therefore the equation right.

Answers
Answer:250
Step-by-step explanation:
j+m=5
50(j+m)=50x5=250
Answer:
If you mean 5(j + m) and j + m = 5 then you answer is 6j + 6m = 5.
If you mean 50j + m and j + m = 5 then there is no solution.
Step-by-step explanation:
j + m = 5
5(j + m)
5(j + m) + j + m = 5
5j + 5m + j + m
6j + 6m = 5
A debt payment of $5,500 is due in 27 months. If money is
worth 8.4% p.a. compounded quarterly, what is the equivalent
payment? Now? 15 months? 27 months? 36 months?
Answers
Step-by-step explanation:
A=P(1+0.084) ^n;
=5500(1
The payment now is $4561.7450, 15 months later $5061.28, 27 months later $5500.00595 and 36 months later $5853.83.
Interest rate = 8.4/4 =2.1% = 0.021 every 3 months
The debt of $5500 is due in 27 months.
What is the formula to find compound interest?The formula to find the compound interest is [tex]FV=PV(1+r)^{n}[/tex].
Now, [tex]PV=FV(1+r)^{-n}[/tex].
The payment now:
5500*(1.021)^-9 = $4561.7450
So if $5500 is due in 27 months its current value is $4561.7450.
( b) 15 months from now? 5 quarters
FV(15months)= 4561.75*1.021^5
4561.75*1.021^5 = $5061.28
(c) 27 months from now? 9 quarters
FV(15 months)= $5500 that was given in the question
Verification:
FV(27months)=4561.75*1.021^9
4561.75*1.021^9 = $5500.00595
(d) 36 months from now? 12 quarters
FV(36months)=4561.75*1.021^12
4561.75*1.021^12 = $5853.83
Therefore, the payment now is $4561.7450, 15 months later $5061.28, 27 months later $5500.00595 and 36 months later $5853.83.
