2=9x+5 I think this is how you do it because you say that it have to equal to 2

Answer:
So we have x+3 if -3<=x<=-1
and 5 if -1<=x<=1
Step-by-step explanation:
The one piece from -1 to 1 is horizontal so the line is in the form of y=a number. It goes through 5 on the y-axis so the equation there is y=5.
From -3 to -1, that is a line with positive slope (since that part is increasing).
Slope=rise/run
We see from the filled in dot to the unfilled in dot that the rise is 2 and the run is 2 so the slope is 2/2=1.
So if we did extend this line where we go at on the y-axis? It would go through 3 because starting from the unfilled dot and rising 1 and running 1 will get us to the 3 on the y-axis.
The equation of a line in slope-intercept form is y=mx+b.
We have m=1 and b=3 so the equation is y=1x+3 or just y=x+3.
So we have x+3 if -3<=x<=-1
and 5 if -1<=x<=1
Answer:
20%
Step-by-step explanation:
To find out the percent decrease of the price of the lotion, the first step is to get the amount of the decrease in price.
The lotion is normally $3.00 for the bottle.
This week, it's at $2.40 for the same bottle.
The difference is then of $0.60 per bottle.
Now, we take that $0.60 and we divide it by the original price of $3, we get:
$0.60 / $3.00 = 0.20
So the special is a reduction of 20% from the original price of $3.00 per bottle.
