Given:p: x – 5 =10q: 4x + 1 = 61Which is the inverse of p → q?

A
If x – 5 ≠ 10, then 4x + 1 ≠ 61.
B
If 4x + 1 ≠ 61, then x – 5 ≠ 10.
C
If x – 5 = 10, then 4x + 1 = 61.
D
If 4x + 1 = 61, then x – 5 = 10.

Given:p: Two linear functions have different coefficients of x.q: The graphs of two functions intersect at exactly one point. Which statement is logically equivalent to q → p?

A
If two linear functions have different coefficients of x, then the graphs of the two functions intersect at exactly one point.

If two linear functions have the same coefficients of x, then the graphs of the two linear functions do not intersect at exactly one point.
C
If the graphs of two functions do not intersect at exactly one point, then the two linear functions have the same coefficients of x.
