1.
3 x 4 = 12
3 + 4 = 12
The two integers a and b are : 3 and 4
2.
-4 x 1 = -4
-4 + 1 = -3
The two integers a and b are : -4 and 1
3.
-3 x -3 = 9
-3 + -3 = -6
The two integers a and b are : -3 and -3
There you go! I really hope this helped, if there's anything just let me know! :)
Simplify both sides:
x
—- = -9
4
now isolate the variable (x):
x= -9 • 4
x= -36
So an exponential equation is gonna be used for this problem. The formula for such is

, in which the a variable is the initial value and the b variable is the growth/decay rate.
For this situation, 1200 is gonna be your a variable since you've started out with it. And as for your b variable, its gonna be 107.3%, or 1.073, since it's increasing.
Your equation should look like this:

and from here just plug in 10 into the x variable and solve.
Multiply (1.073)^10 (don't round answers until the end), and take that answer and multiply it with 1200, your answer should be $2427.61.
83, 89, and 97 are three primes between 80 and 100.
The primes between 30 and 50 are 31, 37, 41, 43, and 47, all of which are odd. All other numbers between 30 and 50 are composite.
To mentally find 2*50*25, you could either first multiply 25 by 2, to get 50*50, which can easily be calculated as 2500, or you could multiply the 50 by 2, for a result of 100*25, which is clearly also 2500.
Answer:
The zeroes of this function are x=-5 and x=4
