Add -5 to each side of the inequality:
-3 ≤ x + 5 ≤ 8
-3 - 5 ≤ x + 5 - 5 ≤ 8 - 5
-8 ≤ x ≤ 3
Since x is an integer, there are 12 possible solutions belonging to {-8, -7, ..., 1, 2, 3}. In the sum of these solutions, the integers -3 to 3 cancel out, and the rest give
-8 - 7 - 6 - 5 - 4 = -30
Answer:
B
Step-by-step explanation:
We can determine that it is sin, not cos, because the equation goes through the origin (0, 0).
The amplitude is 2 and since the amplitude is a for an equation in the form of asinx, the equation must have 2sinx.
Finally, the period is pi. The regular period of sinx is 2pi, so inside of the si, x must be multiplied by 2, which gets us to 2sin(2x).

Answer:
let x represent the number
12.5n/100=4.3
12.5n=4.3x100
12.5n=430
n= 430/12.5
n= 34.4
