I believe the answer is 30 if u look at this equation you'll notice the numbers adde go down by two, correct me if I'm wrong.Hope this helps
Answer:
36
Step-by-step explanation:
12*3=36
36 of 1/3 feet of yarn
1 year = 3.6 % depreciation
100-3.6=96.4
so you do 35,865 ×0.964 = 34,573.86
so the price after a year is £34,573.86
to find out what the price is after 10 years you do 34,573.86 (0.964) to the power of 10
which equals £23961.73
I hope that was helpful :)
The lines are
i) y=-x+6
ii) y=2x-3
The solution of the system of equations is found by equalizing the 2 equations:
-x+6=2x-3
-2x-x=-6-3
-3x=-9
x=-9/(-3)=3
substitute x=3 in either i) or ii):
i) y=-3+6=3
ii) y=2(3)-3=6-3=3
(the result is the same, so checking one is enough)
This means that the point (3, 3) is a point which is in both lines, so a solution to the system.
In graphs, this means that the lines intersect at (3, 3) ONLY
Answer: The graph where the lines intersect at (3, 3)
