Answer:
B,C,D,F, those are yhe right answer
Answer:
a) 4*x + 50 ≤ 100
b) Domain x (0 ; 12 ) Range f(x) ( 50 ; 98 )
Step-by-step explanation:
The constraint is:
4*x + 50 ≤ 100 where "x" is the number of persons
b) Domain for x
x = 0 up to x = 12 x (0 ; 12 )
c) Range for f(x)
f(x) = 4*x + 50
f(0) = 4*0 + 50 f(0) = 50
f(12) = 4*12 + 50 f (12) = 98
f(x) ( 50 ; 98 )
(a) <em>Slope and intercept
</em>
In the equation y = 2x +8, the coefficient of x is the slope and the constant is the y-intercept.
Thus,
slope = 2; y-intercept = 8
===============
(b) <em>Rate of change and initial amount
</em>
The rate of change is the slope. The units of y are baskets of apples and the units of x are hours. So,
rate of change = 2 baskets of apples per hour
The initial amount when x = o.
When x = 0, y = 8. so
Initial amount = 8 baskets of apples
===============
(c) <em>Graph
</em>
Your graph should look something like the one below.
