No the inequality symbol only changed when you divide a negative number from both sides.
By slope you mean gradient? If yes then it’s 1 and the y intercept is (0, -7)
Answer:
Step-by-step explanation:
This is part of the Isosceles Triangle Theorem. If one theta is equal to the other theta (and they are or else they wouldn't both be theta; one would be theta and the other might be beta), that means that the sides across from those congruent angles are also congruent. That means that
6x + 6 = 9x - 9 and
15 = 3x so
x = 5
What triangle are you talking about?
