Answer:
x = 133/4 or x = 33.25 decimal
Step-by-step explanation:
Solve for x:
7 - 4 x = -126
Subtract 7 from both sides:
(7 - 7) - 4 x = -7 - 126
7 - 7 = 0:
-4 x = -7 - 126
-7 - 126 = -133:
-4 x = -133
Divide both sides of -4 x = -133 by -4:
(-4 x)/(-4) = (-133)/(-4)
(-4)/(-4) = 1:
x = (-133)/(-4)
Multiply numerator and denominator of (-133)/(-4) by -1:
Answer: x = 133/4
Answer:
P(she selects the route of four specific capitals) = 1 in 2,686,320 or 3.72 x 10⁻⁷
Step-by-step explanation:
Assuming that the order at which she visits each of the four cities matters, the number of possible routes is the permutation of choosing 4 out of 42 capitals:
Therefore, the probability that she selects the route of four specific capitals is 1 in 2,686,320 or 3.72 x 10⁻⁷
Answer:
a and d is the correct answer
Step-by-step explanation:
2 sides and 1 angle I think...
F(t) = 2(0.4)^t
To solve f(-2) we should substitute t = -2 into the equation:
f(-2) = 2(0.4)^(-2)
= 2(6.25)
= 12.5
