First you solve the inequality. Add the variables that can be added together. That would be -3 + 1=2. Now the equation is 2 + x<6. After you change the 2 into a negative and put it under the 6 and subtract. that is 3. 3 is the number you put on the number line. When you fine and plot three you make a dot above it. You fill in the dot since the less then sign has a line beneath it. Then you draw a line from the dot to the end of the number line from the direction the sign is facing. It’s a less then sign, so you would draw the line to the left.
Hi!
We will solve this using rations, like this:
$920 equals to 115% = 1,15
$x equals to 100% = 1
_______________________
x = (920*1)/1,15
x = 920/1,15
x = 800
Store earned 15%, or in this case 920 - 800 = $120.
Hope this helps!
Answer:

Step-by-step explanation:
Using the rule of logarithms
•
x = n ⇔ x = 
Hence
with b = 4 and n = - 2
= - 2, then
=
← in exponential form
The slope of the perpendicular line is the negative reciprocal of that of the given line, so is
-1/(3/5) = -5/3
Then the point-slope equation of the perpendicular line can be written as
y = (-5/3)(x -15) -5
y = (-5/3)x +20
The y-intercept of the perpendicular line is y=20.
