The graph shows Marcia's walk.
Which statement best describes what Marcia could be doing on the interval from B to C?
A. Marcia is running home.
B. Marcia is walking home.
C. Marcia is turning a corner.
D. Marcia is stopping to rest.
Answers
Answer:
D. Marcia is stopping to rest
Step-by-step explanation:
At intervals B to C, we can see that Marcia's distance from home has not risen nor dropped. We can safely assume that she is not moving. Of course, time has not stopped, because the line continues to move from left to right. So, Marcia is likely stopping to rest for a moment.

Answers
Answer:
-(x-120)
x-(-12)
-(x-(-12))
0
x / 3
-(x/3)
0
Step-by-step explanation:
1. || x-120||, if x<-120.
If x is less than -120, then x - 120 will be a negative number.
Since absolute value will make a negative number positive, the answer will be -(x-120).
2. ||x-(-12)||, if x > -12.
Basically x -(-12) = x + 12. If x is greater than -12, then ||x+12|| will be positive. The answer is x-(-12).
3. ||x-(-12)||, if x < -12.
Again, x-(-12) = x + 12. If x is less than -12, ||x+12|| will be negative.
Absolute value makes a negative number positive. The answer is -(x-(-12)).
4. ||x-(-12)||, if x = -12.
So we can substitute x with -12. ||-12-(-12)|| = ||-12+12||, which equals ||0||, which is also just 0. (Answer is 0.)
5. ||x / 3||, if x > 0.
Any positive number divided by another positive number will be positive, meaning you can just take out the absolute value sign. Answer is x /3.
6. ||x / 3||, if x < 0.
Any number less than 0 is negative, and any negative number divided by a positive number will be negative. If we take out the absolute value, we'll have to reverse it with a -. Answer: -(x/3).
7. ||x / 3||, if x = 0.
||0/3|| = ||0||, which is still 0.

The table shows the number of bottles of different kinds of juice sold at a cafeteria on Monday.
If the cafeteria has 80 customers on Tuesday, which prediction for Tuesday is NOT supported by the data in the table?
Pls answer ASAP
Answers
First you need to add up everything to find out the amount of costumers more Monday. You will get 40. Then you would have to multiply 40 by 2 to get 80 which is the total amount of costumers for Tuesday. This means that you have to double the amount of everything on the table to find out how much of each item was sold. The questions says which is NOT supported by the table. When you do the math you see that everything is accurate except C because the number of apple juice sold on Tuesday is 22 and the number of cranberry juice sold on Tuesday is 14. 22 is not 6 times more than 14 which makes C the correct answer.

She can expect to hit the bullseye 5 times.
Answer:
A. 5
Step-by-step explanation:
Regina throws 25 darts and hits the bullseye 20% of the time. So we would set up the equation as 0.20*25 (as we are looking for 20% of 25 and of means multiplication and 20% is 0.20). 0.20*5=5 so she can expect to hit the bullseye 5 times. Therefore, A is the correct answer choice.

Basically, try finding the x and y intercept for each problem and then make those your coordinates!!
Step-by-step explanation:
1) So to answer these questions first plot the "b" value (which in number 1's case would be 3).
2) Go up three spaces on the graph. and that should leave you at the point (0,3) Plot this point.
3) Now go down 3 (-3x) and go over one point to the right(this should put you at point (1,1). Plot this point.
4) Move on to the next equation in number one. Go up three spaces on the graph.
5) Go down one and over one until you find that you have plotted a point in which both equations intercept (this point would be (0,3).
6)Repeat this process for the rest of the problems
