Answer:

Domain: c)

Range: d)

Step-by-step explanation:

The domain means all of the possible x-values. To find the domain, find the leftmost and rightmost value of x. They are 0 and 8.5.

The range means all of the possible y-values. To find the range, find the lowest and higher values for y. They are 0 and 12.5.

"All numbers" means x or y can be any number, decimal decimal numbers. "Whole numbers" mean x or y can only be numbers that don't have decimals.

Both x and y can be decimal numbers because the graph is not broken up. If it could only be whole numbers, the graph would be dots.

Answer:

Vertical angles = 81 degrees

Angle (4y-1) = 99 degrees

Linear pair = 81 + 99 = 180 degrees

Step-by-step explanation:

2x + 5 = 3x - 33 (vertical angles)

33+5 = 3x - 2x

38 = x

3(38) - 33 = 81 degrees

4y - 1 + 81 = 180 (linear pair angles)

4y = 180 - 80

y = 100/4

y = 25

4(25) -1 = 99 degrees

Answer:

D. $x = 3 \pm \sqrt{10}$

Step-by-step explanation:

$x^2 - 6x - 1 = 0$

$x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}$

a = 1; b = -6; c = -1

$x = \dfrac{-(-6) \pm \sqrt{(-6)^2 - 4(1)(-1)}}{2(1)}$

$x = \dfrac{6 \pm \sqrt{36 + 4}}{2}$

$x = \dfrac{6 \pm \sqrt{40}}{2}$

$x = \dfrac{6 \pm \sqrt{4 \times 10}}{2}$

$x = \dfrac{6 \pm 2 \sqrt{10}}{2}$

$x = 3 \pm \sqrt{10}$
