2(9x+12) + 2(3x-4)
because there are four sides, and it is a parallelogram, the opposite sides are equal. the answer is 24x+16
Think of sea level as 0 on number line

Step-by-step explanation:
The question is incomplete. I will assume the function is:
Required
Determine the rate of decay
In an exponential function 
,
The decay rate of the function is calculated as:
By comparison:
So, the equation becomes:
Make r the subject
<em>The rate of decay is 0.14</em>
Answer:
Step-by-step explanation:
S+J+M=36
J=S-2 or J=x-2
M=S-16 or M=x-16
Answers:
- Choice B) y = (1/4)x
- The unit rate is <u> 3.89 </u> dollars per pound. It costs <u> 23.34 </u> dollars for a turkey that weighs 6 pounds.
=====================================================
Explanations:
- Direct proportional equations are always in the form y = kx, where k is some constant. In the case of choice B, we have k = 1/4. Visually, direct proportion equations are always straight lines and go through the origin.
- Divide $34.99 over 9 to get 34.99/9 = 3.88777 approximately. This rounds to 3.89, so it costs $3.89 per pound. That's the unit rate. Multiply this by 6 to get 6*3.89 = 23.34 which is the cost of the 6 pound turkey.
