Christi buys 48 barrettes. She shares the barrettes equally between herself and her 3 sisters. Write an expression to represent the number of barrettes each girl gets.

Answers

Answer: $48/4$

Step-by-step explanation:

Given : Total barrettes bought = 48

The total number of people shares the barrettes =3+1=4 (Including Christi)

Now, if She shares the barrettes equally between herself and her 3 sisters., then the expression to represent the number of barrettes each girl gets will be :-

$\text{Total barrettes}/\text{Total persons}\n\n=48/4$ ( Using division operation)

Hence, the expression to represent the number of barrettes each girl gets:

$48/4$

48 barrettes is being shared by a total of 4 people (herself+3 sisters=4)
What you're going to do is divide 48 by 4 and each one receives: 12 barrettes.

How do you find the slope

Answers

Remember that the slope of a line never changes, so you can choose whatever 2 points you want and you will always get the same slope. Calculate the rise and run (You can draw it on the graph if it helps). The slope is 2/4, which , of course, you can simplify to ½.

Answer:Use the slope formula, m=y2-y1/x2-x1

PLEASE HELP!!! URGENT!!! Graph the piecewise function
f(x) = 3x-5 if x≤−1
-2x+3 if −1 2 if x≥4

Answers

Answer:

Step-by-step explanation:

To graph a piecewise function, we need to graph each piece separately and then put the pieces together.

The first piece of the function is f(x) = 3x-5 if x ≤ -1. This is a linear function with a slope of 3 and a y-intercept of -5. To graph this piece, we can plot two points on the line and then connect them.

For example, we can plot the points (-1, -2) and (-2, -11). Once we have plotted the points, we can connect them with a straight line.

The second piece of the function is f(x) = -2x+3 if -1 < x ≤ 2. This is also a linear function with a slope of -2 and a y-intercept of 3. To graph this piece, we can plot two points on the line and then connect them.For example, we can plot the points (0, 3) and (1, 1). Once we have plotted the points, we can connect them with a straight line.

The third piece of the function is f(x) = 2 if x > 2. This is a constant function, so it will be a horizontal line at y = 2.Once we have graphed each piece of the function, we can put the pieces together to get the graph of the entire function.
