Answer:

The answer would be y= -2x+1

Step-by-step explanation:

To get this answer, you are going to find the y-intercept and the slope (rise over run). The y-intercept is where the line passes through the y-axis.

When looking at this graph we see the line passes through the y-axis at (0,1) making our y-intercept positive 1.

To find the slope, we are going to find our rise over run. So, essentially, we already know that only answer B has a positive 1, so looking at this slope (using y=mx+b), we see -2. We can just put this over 1 and our rise over run will be -2/1. By counting these spaces on the graph, we can see this matches the points the line passes through.

31. Students are going through a three-step process to obtain their ID cards. Each student will spend 2 minutes at the registrat

mars1129 [50]

Answer:

The answer is 72 minutes.

Step-by-step explanation:

The first step will be the registration desk, which last 2 minutes.

The second step is going to one of the three cashiers, this step takes 10 minutes.

The third step is to visit one of the four ID processing stations, to take their picture and to print the ID card. this step take 20 minutes.

Demand rate= 0.5 students per minute

This means 1 student every 2 minutes.

The total amount of time of the three-step process is 32 minutes.

During 40 minutes 20 students will start their process. These means that the student number 20 will start his/hers process at the minute number 40 of the whole process. As he/she is the last one, no one will finish their process before him/her.

The process takes 32 minutes.

We just need to add 40 minutes to the total amount of time of the three-step process takes, which is 32 minutes.

$time=40+32=72 minutes$

Therefore to process 20 students it will take 72 minutes.

Solve 2(y – 3) = 1.2 – y.

Ne4ueva [31]

First write down your equation. 2(y-3)=1.2-y. the distribute your 2. 2 times y is 2y and 2 times -3 is -6. now you have 2y-6=1.2-y. bring your y to the other side of the equation with the opposite sign and do the same with your 6. you have 2y+y=1.2+6. combine the like terms and constants. now you have 3y=7.2. divide bother sides of the equal by 3 to get y alone. 3y/3= 7.2/3. your answer is y=2.4.

A Web site defines a regular polygon as “a polygon with all angles the same measure.” Is this definition valid?

grandymaker [24]

Answer:

Yes, because all regular polygons fit this definition.

Choice D is correct

Step-by-step explanation:

A polygon is said to be regular if it is equiangular that is all its angles are equal and equilateral which implies that all its sides have equal length. Examples of regular polygons include;

Regular pentagon

Regular octagon

At 9:00 pm bob leaves his home and starts walking to the bus stop at a constant speed of 9.3 feet per second. bob's house is 432

klio [65]

a. define variables for the quantities that are changing (be specific).
We define variables:
t = time in second
d = distance traveled
The variables that are changing are t and d.
As the time increases, the distance decreases.

b. what does it mean to say bob walks at a constant speed of 9.3 feet per second?
It means that for every second that passes, Bob walks 9.3 feet.

c. consider the formula d = 4320 - 9.3t i. what does t represent? ii. what does 9.3t represent? iii. what does d represent?
For this case we have:
t = represents the time in seconds
9.3t = represents the distance traveled by Bob
d = represents the distance Bob must travel to get to the bus stop.
