Answer:
The range consists of all real numbers greater than and equal to -8
y >= -8
Step-by-step explanation:
The range of the function f(x)=-3(x+6)2-8 is ?
This is a parabola.
notice it opens upward starting from the vertex (6, -8)
so the range goes from -8 and upward
X and y are the times in hours that he travelled on foot and on bus
x + y = 1.5 * by 5:-
5x + 5y = 7.5
5x + 60y = 35 subtract:-
55y = 27.5
y = 0.5
and x = 1.5 - 0.5 = 1
so he walked for 1 hour
distance he walked = average speed * time = 5*1 = 5 miles.
