Answer:
x=2 and y=−6
sorry this is pretty long, I did not know if you needed the steps or not
Step-by-step explanation:
−2y−10=x;−10x−y=−14
Solve−2y−10=x for x
−2y−10=x
−2y−10+−x=x+−x
−x−2y−10=0
−x−2y−10+2y=0+2y
−x−10=2y
−x−10+10=2y+10
−x=2y+10
-x/-1=2y+10/-1
x=−2y−10
Substitute−2y−10 for x in−10x−y=−14
−10x−y=−14
−10(−2y−10)−y=−14
19y+100=−14
19y+100+−100=−14+−100
19y=−114
19y/19=-114/19
y=-6
Substitute−6 for y in x=−2y−10
x=−2y−10
x=(−2)(−6)−10
x= 2
x=2 and y=−6
Answer:
yeah that's the correct answer
Formula to find the arc length is:

Where, s= arc length,
r = radius of the circle
\theta = central angle in degrees.
According to the given problem, \theta= 150 and r =2.4.
So, first step is to plug in these values in the above formula to get the arc length.

=


So, arc length is
.
Answer:
Interes ganado= €59.07
Step-by-step explanation:
Dada la siguiente informacion:
300€ durante 5 años al 0.3% de interés compuesto mensual.
<u>Para calcular el valor final de la inversión y el interés ganado, debemos usar la siguiente formula:</u>
FV= PV*(1 + i)^n
Present Value= 300
i= 0.003
n= 5*12= 60 meses
FV= 300*(1.003^60)
FV= 359.07
Interes ganado= 359.07 - 300
Interes ganado= 59.07
