Answer:
x=9
Step-by-step explanation:
Answer:
josh vendió 17 libros recaudando 306 dolares .
jessica vendió 255 libros recaudando 4590 dolares.
Step-by-step explanation:
Sustituimos por variables :
libros que vendió Jessica = x
libros que vendió Josh = y
entonces:
x + y = 272
Jessica vendió 15 veces mas libros que josh:
x = 15y
Reemplazamos en la anteriior ecuacion:
15y +y = 272
16y = 272
y = 17
Reemplazamos en la primela ecuacion :
x + 17 = 272
x = 255
x=-3 then y= 27
x= -2 then y= 9
x=2 then y: 
x=3 then y: 
The graph of the function decreases from left to right.
Option C is correct.
Step-by-step explanation:
We are given the function: 
and we need to fill the table
if x = -3 then y=?
Putting value of x in the given function:


Applying exponent rule a^-b= 1/a^b

if x = -2 then y=?
Putting value of x in the given function:


Applying exponent rule a^-b= 1/a^b

if x = 2 then y=?
Putting value of x in the given function:


Applying exponent rule a^-b= 1/a^b

if x = 3 then y=?
Putting value of x in the given function:


Applying exponent rule a^-b= 1/a^b

So, x=-3 then y= 27
x= -2 then y= 9
x=2 then y: 
x=3 then y: 
Graph of the function is shown in figure attached.
The graph of the function decreases from left to right.
Option C is correct.
