Ответ:
x < 3
Step-by-step explanation:
Step 1: Write inequality
4x + 8 > 2(3x + 1)
Step 2: Solve for x
Distribute 2: 4x + 8 > 6x + 2Subtract 4x on both sides: 8 > 2x + 2Subtract 2 on both sides: 6 > 2xDivide both sides by 2: 3 > xRewrite: x < 3Here we see that any value smaller than 3 will be a solution.
Ответ:
f(n) = 8 x 1.17^(n)
f(16) = 8 x 1.17^(16)
f(16) = 8 x 12.330...
f(16) = 98.64243...
This is right because
8 x 1.17 = 9.36
9.36 x 1.17 = 10.9512
10.9512 x 1.17 = 12.812904
