Answer B
Or in other words helicopter descends 2000ft every 5 minutes.
Solution for the system of linear equations is (4, - 3)
<u>Step-by-step explanation:</u>
Step 1:
Given system of equations
x - 3y = 13 -------- (1)
2x + 4y = - 4 ----- (2)
Step 2:
Multiply eq(2) with 2 to make coefficients of x equal.
2x - 6y = 26 ------ (3)
Step 3:
Subtract eq(2) from eq(3)
⇒ - 10y = 30
⇒ y = -3
Step 4:
Find value of x by substituting value of y in eq(1)
⇒ x - 3 × (-3) = 13
⇒ x + 9 = 13
⇒ x = 4
If the expression is 2*x*3, x must be 1/3 in order to cancel out the 3 which would leave the 2.
Answer:
Recall from Logarithm law Log a - Log b = Log (a/b)
so, Log 2 - Log 4 = Log ( 2/4)
= Log ( 1/2).
Also from the law
Log (a/b) = Log a - Log b
i.e Log (1/2) = Log 1 - Log 2
Recall: Log 1 = 0
which implies : Log 1 - Log 2 = 0 - Log 2
= - Log 2
