Answer:
{-1, 2}
Step-by-step explanation:
The quantity x + 1 changes sign at x = -1; equivalently, x + 1 = 0 when x = -1.
If x = -1, then |x+1|+|x−2|=3 becomes |-1 + 1| + |-1 −2|=3, which is TRUE. So x = -1 is a solution.
If x = 2, then we have the equation |2 + 1| + |2 − 2|=3, or |2 + 1| = 3, which is TRUE. So x = 2 is also a solution.
Answer:
8
Step-by-step explanation:
the degree is the highest exponent value
Answer: Choice B) 
Work Shown:
Note: secant is positive in quadrant Q4, when theta is between 3pi/2 radians and 2pi radians (270 degrees and 360 degrees). So that's why we don't consider the minus form of the plus minus.
Answer:
36x
Step-by-step explanation:
18x / 19 = ? / 57
(18x * 3) / (19 * 3) = ? / 57
You multiply by 3 in both the numerator and the denominator.
36x / 57 = ? / 57
After you multiply, your answer equals 36x.
? = 36x
Yes you are right because will be 102 - 52 = 50 degrees
