I hope this helps you
distance=speed×time
first cars time t
second cars time t+3
same distance
distance=55.t
distance=40. (t+3)
55t=40 (t+3)
55t-40t=120
15t=120
t=8
t+3=11
Answer:
see the explanation
Step-by-step explanation:
Let
x ----> the number of males on the elevator
y ----> the number of females on the elevator
we know that
The inequality that represent this situation is
The solution of the inequality is the shaded area below the solid line
The slope of the solid line is negative
The y-intercept of the solid line is (0,18)
The x-intercept of the solid line is (15,0)
see the attached figure
The solution is the triangular shaded area
The maximum number of females is 18 (when the number of males is zero)
The maximum number of males is 15 (when the number of females is zero)
The given expression is,
y = f(x)
This mean that the value of the function is the value that correponds to the y value for a particular x.
From the graph we can see that,
Thus, f(0) = 2.
He ordered 12"x12" 12"
= 12^3
since 12" is one foot he has 1x1x1 cubic feet
or 1 cubic foot or 1^3 cuft
