<h3>
Answer: x = 29</h3>
======================================================
Work Shown:
x+61 = 90
x+61-61 = 90-61
x = 29
------------
Explanation:
- The first step is valid because the two angles x and 61 are complementary angles. They form a right angle or 90 degree angle.
- In the second step, I subtracted 61 from both sides to undo the "+61".
Answer:
Domain: -4 < x < 4
Zeros: (-2, 0), (0, 0) and (2, 0)
The function is positive if: 0 < x < 2
The function is negative if: -4 < x < 0 and 2 < x < 4
Step-by-step explanation:
Domain of the function are those x values where the function is defined, For this case, -4 < x < 4
Zeros of a function are those x values where y = 0, that is, the graph intersect x-axis. For this case, the points are: (-2, 0), (0, 0) and (2, 0)
The function is positive if the graph o the function is above x-axis. For this case, the function is positive at the interval (0, 2)
The function is negative if the graph o the function is below x-axis. For this case, the function is negative at the intervals (-4, 0) and (2, 4)
