Answer:
.
Step-by-step explanation:
From the given graph it is clear that the y-intercept is 16.
The line passes through (-2,24) and (2,8). So, slope of line is
Slope intercept form of a line is
where, m is slope and b is y-intercept.
Substitute m=-4 and b=16 in the above equation.
Therefore, the required equation is
.
Use the estimate but that should be more than the exact price

Answer:
72, 216 , 252
Step-by-step explanation:
Deje que lo que ella leyó inicialmente sea x páginas.
La segunda semana leyó 3 veces esto = 3 * x = 3x.
La tercera semana leyó 5 veces la primera semana menos 108 = 5x-108.
Así que agreguemos todos juntos para obtener x. 3x + x + 5x-108 = 540.
9x = 540 + 108 9x = 648 x = 648/9 = 72 páginas.
Leyó 72 páginas la primera semana.
Ella leyó 3 * 72 en la segunda semana = 216 páginas En la tercera semana leyó 5 (72) -108 = 360-108 = 252 páginas
