S the difference of 2 squares:-
a^2 - b^2 = (a + b)(a - b)
so her it is (2y + z)(2y - z)
The x coordinate of the vertex = -b/2a = -(-6) / 2*34 = 0.08824
y coordinate = 34(0.08824^2 - 6(0.08824) + 15 = 14.735
so its (0.088, 14.735) correct to 3 decimal places
Answer:
Step-by-step explanation:
- −2x + 5(x − 2) > 7x − 6
- -2x + 5x - 10 > 7x - 6
- 3x - 7x > - 6 + 10
- -4x > 4
- x < - 1
- x = (-∞, -1)
The graph is all points to the left from -1, where -1 is not included
I believe the answer to this is F and i think D also
