Answer:
Below in bold.
Step-by-step explanation:
3x + y = -1
2x + y=0
Subtract to eliminate y:
3x - 2x + y - y = -1 - 0
x = -1
So, substituting for x in the first equation;
3(-1) + y = -1
y - 3 = -1
y = 2.
The solution is the ordered pair (-1, 2).
The system is a pair of straight lines which intersect at the point (-1, 2).
Answer:
5h+5
5(h+1)
Step-by-step explanation:
Equivalent expressions are the ones that look different but are the same. As the statement says that mason works h number of hours during the 5 day week and 5 hours on the weekend, you can write the following expression:
5h+5
h= number of hours Mason works
Then, you can find the common factor to get an equivalent expression:
5(h+1)
According to this, the equivalent expressions are:
5h+5
5(h+1)
