Step-by-step explanation:
The two rectangles are similar and the scale factor is
I guess this is the answer
Answer: 
Step-by-step explanation:
To solve this exercise it is important to remembet the definition Definition of a Logarithm:
If 
and, 
, then 
is equivalent to 
(which is the exponential form).
Knowing this definition and having the following logarithmic equation:
You can identify that:
Therefore, susbtituting values into , you can rewrite this equation as an exponential equation. Then:
9514 1404 393
Answer:
- y < -2x +3
- y > 1/2x -2
Step-by-step explanation:
To find the equation of each boundary line, look for the y-intercept. Then find the rise and run to the next grid intersection to the right that is crossed by that line. The equation for the line is ...
y = mx + b . . . . . . m = rise/run = slope; b = y-intercept.

The lines are both dashed, so the inequalities will not include the "or equal to" case. For line (1), the shading is below the line, so the appropriate inequality symbol is <. For line (2), the shading is above the line, so the appropriate inequality symbol is >.
__
<u>Line 1</u>
y-intercept = +3. m = -2/1 = -2
y < -2x +3
<u>Line 2</u>
y-intercept = -2. m = 1/2
y > 1/2x -2
