Answer:
1792, -7168
Step-by-step explanation:
If you can find the constant number multiplied in the pattern, you know that it multuplies by -4. -448 times -4 will be a positive number, which the answer is 1792 if you use the calculator, then you use 1792 and multiplie that by -4 to get -7168.
That's the answer, 1792, then -7168.
Answer:
B. Increasing in x < -1 and decreasing in x > -1.
Step-by-step explanation:
We are given the graph of a function and is required to find the interval in which the function is increasing, decreasing or constant.
Now, from the graph we can see that the critical point i.e. the point at which the graph changes the direction is x = -1.
We observe that the function on the left side of x = -1 is going upwards to reach the point x = -1 and the function on the right side of x = -1 is going downwards.
Hence, we get that the function in increasing in x < -1 and decreasing in x > -1.

Answer:
1010
Step-by-step explanation:
There are a whole class of questions that rely on the method to this one.
First add up what you know
1270 + 1150 + 870 + 1450 = 4740
Now add on the 5th month (which you don't know. Call it x)
4740 + x
Divide by 5
(4740 + x)/5 = 1150 and that is your equation
Solution
Multiply both sides by 5
5*(4740 + x) / 5 = 1150 * 5
4740 + x = 5750
Subtract 4740 from both sides
4740 - 4740 + x = 5750 - 4740
x = 1010
Which seems kind of low, but that's what the numbers come to.
multiply both sides by 2 to get
2A = (a+b)*h
divide both sides by h
to get 2A/h = a+b
subtract b from both sides to get a = 2A/h -b
3rd choice is correct
