Answer:
9,200$ is what he would have after the 40 years
Step-by-step explanation:
9% of 2,000$ is 180$
take the 180$ and multiply it by 40 (40 is the years)
and you get 9,200$
Answer:
Step-by-step explanation:
For the limit of a function to exist, then the right hand limit of the function must be equal to its left hand limit as shown;
If the function is f(x), for f(x) to exist then;
Given the function;
Lets check if the above statement is true.
The right hand limit of the function occurs at x> 9
f(x) = 9-x
The left hand limit occurs at x<9
f(x) = x+9
From the above calculation, it can be seen that 
, this shows that the function given does not exist at the given point.
2 and 4. In equations where the line is parallel, the slope is the same. By eyeing this number 2 is right but number four is right as well because when you put y by itself and divide the 2 from the whole equation, it is ultimately the same and still parallel from the original equation.
Answer:
Elimination (multiplication and subtraction)
There is 1 solution
Step-by-step explanation:
The only way to solve this system of equations is by elimination (multiplication). Let's say that we want to cancel out the x. You multiply the first equation by 5 and you multiply the second equation by 2.
Your equations now are:
10x-5y=55 and 10x+6y=-22
You can subtract these equations to get -11y = 77.
Now that we know that y = -7, we can substitute y in to solve x.
10x-5(-7) = 55
10x=20
x=2
Final answer (2,-7)
