43 is five percent of 860
Answer:
No for the first one, yes for the second.
Step-by-step explanation:
Plug in the given numbers and see if it works.
15(1) + 3(4) = 10
15 + 12 = 10.
27 ≠ 10
Since 27 does not equal 10, we can already see that solution (1,4) will not work for these equations.
Now for the second problem, do the same thing.
10 = 1 + 9.
This is true, but remember to check the second equation just to be sure.
10 = 4(1) + 6
10 = 4 + 6
This is also true, so it (1,10) is a solution for the second system of equations.
Given y + 3.5 = 0.75(x - 2)
when x = 4,
y + 3.5 = 0.75(4 - 2) = 0.75(2) = 1.5
y = 1.5 - 3.5 = -2.
Thus, the ordered pair (4, -2) is the line with equation y + 3.5 = 0.75(x - 2)
When x = -4,
y + 3.5 = 0.75(-4 - 2) = 0.75(-6) = -4.5
y = -4.5 - 3.5 = -8
Thus, the ordered pair (-4, -8) is the line with equation y + 3.5 = 0.75(x - 2)
When x = 1,
y + 3.5 = 0.75(1 - 2) = 0.75(-1) = -0.75
y = -0.75 - 3.5 = -4.25
Thus, the ordered pair (1, 1.75) is not on the line with equation y + 3.5 = 0.75(x - 2)
When x = 7,
y + 3.5 = 0.75(7 - 2) = 0.75(5) = 3.75
y = 3.75 - 3.5 = 0.25
Thus, the ordered pair (7, 0.25) is not on the line with equation y + 3.5 = 0.75(x - 2)
11/3 = 3 2/3....so the minimum number of trips would be 4
Answer: Its also okay for drinking after boiled
Step-by-step explanation:
According to the Department of Food Science in Cornell University, pasteurised or boiled milk has a longer shelf life than raw milk, contrary to the myth that boiling milk will not reduce its lactose content.
