Answer:
x = -1
Step-by-step explanation:
You want ...
f(x) = g(x)
-2x -8 = 4x -2
-6 = 6x . . . . . . . . . . add 2x +2
-1 = x . . . . . . . . . . divide by 6
Answer:
9.81*106
Step-by-step explanation:
X + 58 = 6
x = 6 - 58
x = - 52
The first one is 4
The second one is 2.449489743 or 2.45
There are 10 letters in the set {a, b, c, d, e, f, g, h, i, j} which is the pool of letters to choose from when making these three letter codes.
We have 10 choices for slot 1
Then 9 choices for slot 2. This is because we can't reuse the choice for slot 1
Then 8 choices for slot 3
Overall, there are 10*9*8 = 90*8 = 720 different permutations
Answer: 720
Note: you can use the nPr permutation formula with n = 10 and r = 3 to get the same answer
