<h3>Answer: (-8, 6)</h3>

====================================================

Work Shown:

B = (2,8) is the starting point

B' = (2,-8) after reflecting over the x axis. The y coordinate flips from positive to negative. The x coordinate stays where it is.

----------

(2,-8) is in the form (x,y) with x = 2 and y = -8

$(x,y) \to (y, x+4)\\\\(2, -8) \to (-8, 2+4)\\\\(2,-8) \to (-8, 6)$

This shows (2,-8) translating or shifting to (-8,6) to get to the location for B''

Step-by-step explanation:

Point B(2, 8) reflect to x-axis

It means the x value won't change, the only thing that will change is the y value.

According to it, we can know that B' is (2, -8)

(2, -8) → (-8, 2+4) = (-8, 6) = B''

What type of correlation/association exists?

LuckyWell [14K]

Answer:

Negative Correlation

Step-by-step explanation:

there is a negative correlation between the number of hours you sleep in and the number of hours you are awake during the day as the longer you are either awake or asleep the less time you will be doing the other thing

Here is a graph I made that will hopefully help you understand.

Even if I switched around the label for the x or y-axis, the correlation would still remain the same because the more you stay asleep, the less you will be awake and vice versa.

Steve works two different jobs for a total of 60 hours every Monday through Friday schedule is the same each day and he works th

Semenov [28]

Answer:

Step-by-step explanation:

Steve works:

- 60 hour per week = 12 hours per day (60/5)

- first job: 3 hours per day = 15 hours per week

- x = second job hours per day

equitation:

1st option to calculate:

12 (total hours per day) = 3 (hours per day on first job) + X

9 = X

2nd option to calculate:

60(total hours per week) = 15 (3 hours per day x 5) + x

45 = x

you need to divide 45 / 5 to get the daily hours which is 9

• Trey attended a New Year's Eve event and watched a ball drop at midnight. Prior

jekas [21]

Answer:

x=60.9°

Step-by-step explanation:

Given that the height of ball from the ground is 150ft

The base of the pole with the ball is 80 ft from where Trey is standing

Trey's horizontal line of sight is 6 feet above ground, then;

The height of ball from Trey's horizontal line of sight is;

150ft-6ft = 144ft

To find the angle x, assume a triangle with a base of 80 ft , a height of 144 ft and a slant height that represent the line of sight at an angle x

To get angle x , you apply the tangent of an angle formula where;

tan Ф°= length of opposite site of the angle/length of the adjacent side of the angle

tan x°= 144/80

tan x°= 1.8

x°= tan⁻(1.8)

x°=60.9°
