Answer :
Step by Step Explanation :
1. 6x - 30 - 4x = 12x - 15
2. 2x - 30 = 12x - 15
3. -10x - 30 = -15
4. -10x = 15
5. x = -10/15
6. x = -2/3 (simplified)
Answer:
Up
Step-by-step explanation:
Y= 1x^2 + 3x + 9
Y= Ax^2 + Bx + C
To determine which way a parabola opens just look at the coefficient (the number) of the x^2 - Always use the coefficient that is beside the x^2
So, if the coefficient A is positive the parabola is opening upward
if the coefficient A is negative the parabola is opening downward
