The x-value corresponds to a y-value of 1 is π
Step-by-step explanation:
The given is:
- y = - cos x
- y = 1
- 0 < x < 2π
We need to find x when y is 1
∵ y = - cos x
∵ y = 1
∴ 1 = - cos x
- Multiply both sides by -1
∴ -1 = cos x
- Switch the two sides
∴ cos x = -1
- Use the inverse of cos to find x
∴ x = 
∵ cos(π) = -1
∴ x = π
The x-value corresponds to a y-value of 1 is π

The correct answer is b. The HL theorem says that if the hypotenuse and one leg of a right triangle are congruent to the hypotenuse and one leg of another right triangle, then the triangles are congruent. We know that the hypotenuse is congruent in both triangles because it is shared. We know that one leg of each triangle is congruent because they are marked with a single line.

Answer:
False because a linear equation always crosses the x axis (unless x is zero, which it isn't in this case).
