Answer:

1)13x - 15 = 12x + 16 \\ 13x - 12x = 15 + 16 \\ x = 31

2)9x - 19 = 2x - 5 \\ 9x - 2x = 19 - 5 \\ 7x = 14 \\  \frac{7x}{7}  =  \frac{14}{7}  \\ x = 2

3)16x - 35 = 7x - 8 \\ 16x  - 7x = 35 - 8 \\ 9x = 27 \\  \frac{9x}{9}  =  \frac{27}{9}  \\ x = 3

4)6x - 5 = 13 - 3x \\ 6x + 3x = 5 + 13 \\ 9x = 18 \\  \frac{9x}{9}  =  \frac{18}{9}  \\ x = 2

5)4x - 9 = 6 - x \\ 4x + x = 9 + 6 \\ 5x = 15 \\  \frac{5x}{5}  =  \frac{15}{5}  \\ x = 3

6)5x - 2 = 10 - x \\ 5x + x = 2 + 10 \\ 6x = 12 \\  \frac{6x}{6}  =  \frac{12}{6}  \\ x = 2

hope this helps

Find the vertex of this parabola:<br> y = -5x2 - 10x - 15<br> Enter the correct answer.
oksano4ka [1.4K]

Answer:

Vertex of parabola (-1, -10)

Step-by-step explanation:

For a given quadratic y = ax² + bx + c, the vertex (h, k) is found by computing h = –b/2a, and then evaluating y at h to find k. If you've already learned the Quadratic Formula, you may find it easy to memorize the formula for k, since it is related to both the formula for h and the discriminant in the Quadratic Formula: k = (4ac – b2) / 4a.
