When t = 0, S = 2^0 = 1 
<span>When t = 2, S = 2^2 = 4 </span>

Emily spent $55 from her savings on a new dress. explain how to descibe the change Emily's savings balance in 2 different ways
Step2247 [10]
S= savings before she bought the dress   s - $55 would be her new balance after she bought the dress.

We could also talk about her savings now (after her purchase).   If we let n=now
n + $55 would be her balance before she bought the dress.

What is the slope of the line on the graph?<br> Enter your answer in the box.
Firlakuza [10]

Answer:

I think this is the answer you are looking for. (See below)

Step-by-step explanation:

From the given graph it is noticed that the line is passing through many points.

The coordinates of three given points are (1,5), (-1,-1), (-1,-7)

If a line passing through two points (x1 ,y1) and (x2, y2) , the slope of the lie is defined by, m= y2 - y1/x2 - x1

The line passing through two points (-1,1) and (1,5). So the slope of the line is, m= 5 - 1 / 1 minus -1

m=4/2

Therefore, the slope of the line is 2.

Pls if this is wrong, let me know in the comments. I'm not really good at this topic in math but I hope it helps you. Sorry if it is wrong. Have a good day. :)
