Add the two monthly incomes together:
1400 + 1100 = 2500 a month.
There are 12 months in a year, multiply the monthly income by 12:
2500 * 12 = $30,000 per year.
Answer:
mhmm
Step-by-step explanation:
Answer:
no solution
Step-by-step explanation:
y = -2x + 3
6x + 3y = -3
the substitution method means you plug one equation into the next, because the first equation gives us a solution for y we can go ahead and plug that into y of the second equation
6x + 3(-2x + 3) = -3
6x - 6x + 9 = -3
9 = -3
which is false meaning that there are no solutions and the lines don't touch at any point
Answer: 
Step-by-step explanation:
Remembert that, by definition:
→ 
Then, you can rewrite 
in exponential form:
Now you can solve for the variable "x":
Add 6 to both sides of the equation:
And finally you must divide both sides of the equation by 2, then:
Answer:
-75 and -77
Step-by-step explanation:
This can be wrote as 
. Combine like terms and subtract 2 from both sides to get 
. Divide by two to get 
and then add two to get -75.
