First, you want all the variables to be on one side:
a - 3b = 4
a - b = -2
Now you want to eliminate one of the variables, in this case a is easiest.
Subtract the second equation from the first and you're left with:
-2b = 6
so b = -3
Sub the value of b back into either of the equations and solve for x:
a - (-3) = -2
a = -5
So your answer is (-5,-3)
The first one is arithmetic sequence as each term decreases by same amount
(1/3) as x = 1,2,3,4...
12 months in a yr
57,000 / 12 = 4750 per month
Answer: is If something is a function, every x-value, only has one (1) y-value. If the line x = 0 intersects the graph in two points, there are to values for y (instead of one). Therefore the graph is not a function of x.
Step-by-step explanation: answer is A
Answer: (-1/6)/(3/7)= - 7/18
Solution:
(-1/6)/(3/7)=-(1/6)(7/3)=-[(1)(7)]/[(6)(3)]=-7/18
