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)
Answer:
Step-by-step explanation:
density of oil, d = 30 lb/ft³
Volume of tank, V = l x w x h = 1 x 2 x 1 = 2 ft³
mass of oil, m = Volume x density of oil = 1 x 30 = 30 lb
Work = m x g x h = 30 x 32 x 3 = 2880 units
(39x52=2028) (3.8x62=18.62) 2028 divided by 18.62 equals (108.915145) 108.91
Answer:
27/70
Step-by-step explanation:
This is simple: First, you multiply the numerators. 3x9 is 27. That is the numerator to your answer.
Next, you multiply the denominators. 7x10 is 70. That's the denominator to the answer.
Put them together and you get 27/70.
Hope I helped!!!
