Answers
Answer:
(A) is correct.
Step-by-step explanation:
As we know,
The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
From the first graph:
The line goes through the points:
(-2, 2) and (2, 1)
y - 1 = (1-2)/(2+2)[x -2]
y - 1 = (-1/4)[x -2]
y = -x/4 + 1/2 + 1
y = -x/4 + 3/2
The constant additive rate of change = -1/4
Thus, the function shown in graph (A) has a constant additive rate of change is -1/4 option (A) is correct.
Fatima is selling cookies in a bake sale. She packages 20 cookies in 4 minutes. Describe the relationship between the amount of cookies and the time it takes to package them.
Answers
Based on the number of cookies that Fatima was able to package in a certain amount of time, the relationship between the cookies and the time it takes to package them is a single cookie is packaged in 12 seconds.
How long does it take to package the cookies?To find the amount of time it takes to package the cookies, the formula is:
= Number of minutes / Number of cookies
= 4 / 20
= 1/5
= 0.20 minutes
When converted to minutes, this is:
= 0.20 x 60 seconds per minute
= 12 seconds
In conclusion, it takes 12 seconds to package a cookie on average.

use headlights between sunset and sunrise and at any time when visibility is less than 500 feet to 1000 feet.
Answers
Use headlights between sunset and sunrise and at any time when visibility is less than 500 feet to 1000 feet: TRUE
What are headlights?A headlamp is a lamp connected to the front of a vehicle to illuminate the road ahead. Headlamps are also commonly referred to as headlights, but in the most precise usage, the flashlight is the term for the device itself, and the headlight is the term for the beam of light produced and sold by the device. If you are driving with your high-beam lights on, you must dim them at least 500 feet from any oncoming vehicle to avoid blinding the oncoming driver. If you are within 200-300 feet of the vehicle you are following, you must use low-beam lights. When visibility is less than 500 feet and there is insufficient light/adverse weather, headlights must be turned on for 1/2 hour after sunset to 1/2 hour before sunrise.Therefore, the statement "use headlights between sunset and sunrise and at any time when visibility is less than 500 feet to 1000 feet" is TRUE.

Deb wants to organize a group of friends to go to a karaoke studio Friday night. She must pay $30 to reserve a private karaoke room plus $5 for each person in the group. She also wants to have snacks for the group at a cost of $2 per person. How many people can Deb invite in order to spend a total of $65?
Fill in the blanks to create an equation to represent the situation.
blank x + 2x + blank = 65
Answers
Based on the solution below, the number of people Deb can invite in order to spend a total of $65 is 5 people.
How do we use an equation to find a number?Given:
blank x + 2x + blank = 65 ............................... (1)
Where:
x = Number of people Deb can invite
First blank with x variable = 5; since Deb must pay an additional $5 for each person in the group
Second blank without x variable = 30; since Deb $30 to reserve a private karaoke room
Substituting the relevant values into equation (1) and solving for x, we have:
5x + 2x + 30 = 65
7x = 65 - 30
7x = 35
x = 35 / 7
x = 5

For a show during the halftime break up a football game a stage will be set up on the field the center of the stage is on the 35 yard line if the distance from the center to the outer edges is 11 yards which equation can be used to find the location of the outer edges of the stage
Answers
The absolute value equation that can be used to find the location of the outer edges of the stage is:
|x - 35| = 11.
What is the absolute value function?The absolute function is defined by:
|x| = x, x ≥ 0.|x| = -x, x < 0.It measures the distance of a point x to the origin, hence, for example, |2| = |-2| = 2.
For this problem, the outer edges are 11 yards away from the 35 yards line, hence the equation is:
|x - 35| = 11.
The solutions are given as follows:
x - 35 = -11 -> x = 24 yard line(first edge).x - 35 = 11 -> x = 46 yard line(second edge).More can be learned about the absolute value function at https://brainly.com/question/24734454

Answer:
d = 90° , e = 129° , f = 51°
Step-by-step explanation:
d and 90° are a linear pair and sum to 180° , that is
d + 90° = 180° ( subtract 90° from both sides )
d = 90°
e and 129° are vertically opposite angles and are congruent , then
e = 129°
