Answer:
272
Step-by-step explanation:
note that (f • g)(x) = f(x) × g(x) = (3x - 7)(4x - 5)
To evaluate substitute x = 3 into (3x - 7)(4x - 5)
(f • g)(- 3) = (- 9 - 7)(- 12 - 5) = - 16 × - 17 = 172
A function is seen when you know that for every x value there is one y value. An x value cannot be repeated.
In A, the x coordinates are 3, 4, -3, and 2. They are all different.
In B, they are 2, -1, 5, and 4. Again, they are all different.
Both A and B represent functions.
A and b are the minutes spent on machine A and machine B, respectively.
a+b = 40
b = 40-a
8a + 6b = 300
8a + 6(40-a) = 300
8a + 240 - 6a = 300
2a = 60
a = 30
b = 40-a = 10
30 minutes on machine A and 10 minutes on machine B
Well, first you need to know how many pints go into a quart then with the left over pints that don't make a quart go into the other box. Now I don't have the conversions on hand but you could probably look it up.
