They have 3 Model A machines and 10 Model B machines.
Hope this helps
Answer:
6 + 30 / (4-5) = - 24
Step-by-step explanation:
4-5 goes 1st then you do 6 + 30 .
36 / -1 = -24
Answer:
b=4
Step-by-step explanation:
So, we have the function . We need to find b such that the average rate of change or the slope is -1/8 between the intervel [2, b]. First, let's find f(2).
f(2) = 1/(2) = 1/2
So, we have the point (2, 1/2)
At point b, f(b) = 1/b.
Let's plug this into the slope formula:
Now, we just need to solve for b. First, let's multiply both the numerator and denominator by b (to get rid of the annoying fraction in the numerator).
Now, cross multiply.
Solve for b. Factor using the numbers -4 and -2.
Thus, b=4 or b=2.
However, b=2 is not a possible solution since the interval [2,2] means nothing. Thus, b=4.
The first one, the fourth one, and the last one
B) since 1950 is between 1281 and 2796 add the two valves together and then divide them by two
Not sure of A so ..
