Answer:
(-5, 3)
Step-by-step explanation:
Elimination seems like the best method to use here.
x+y=-2
x-y=-8
---------
2x=-10
Divide everything by two
x=-5
Now plug it back into one of the original equations,
-5+y=-2
Add 5 to everything
y=3
Answer:
y=30x+50 and y=40
Step-by-step explanation:
10 hours seems like the most reliable answer because it matches up the best
Answer:
The second term in the sequence is -9
Step-by-step explanation:
Given the nth term of a sequence to be a(n) = a(n-1)+4 where n is the number of terms of the sequence
If a(1) = -13... (1)
The second term of the sequence is generated for n= 2:
a(2) = a(2-1)+4
a(2) = a(1)+4... (2)
Substituting equation 1 into 2
a(2) = -13+4
a(2) = -9
The second term in the sequence is -8
