Answer:

5. The sum of angles in a triangle is 180° so we can write:

9x - 16 + 3x + 11 + 7x - 5 = 180

19x - 10 = 180

19x = 190

x = 10°

6. Because the measure of an exterior angle is equal to the sum of its two remote interior angles we can write:

17x - 23 = 3x + 17 + 8x - 4

17x - 23 = 11x + 13

6x = 36

x = 6°

WITCHER [35]

Answer:

${b}^{2} - 4ac = 0 - 4 \times 1 \times ( - 4) = 16$

$\sqrt{16} = 4$

$\frac{ - b}{2a} = \frac{0}{2} = 0$

$\frac{ - 4}{4} = - 1$

it is decreasing from negative infinity to 0

Complete the solution table from left to right for the quadratic function. (I did not select an answer, that was a mistake) Than

Karo-lina-s [1.5K]

Answer: OPTION D

Step-by-step explanation:

To complete the table, you need to substitute the values of "x" given in the table into the quadratic equation $y=x^{2}-x-6$ to obtain the corresponding value of "y".

Then:

When $x=-5$ :

$y=(-5)^{2}-(-5)-6$

$y=24$

When $x=-3$ :

$y=(-3)^{2}-(-3)-6$

$y=6$

When $x=-1$ :

$y=(-1)^{2}-(-1)-6$

$y=-4$

When $x=2$ :

$y=(2)^{2}-(2)-6$

$y=-4$
