Answer:
w=30 l=125
Step-by-step explanation:
Perimeter =2l+2w
p=310
w =width
4w+5 = length(4 times plus 5 the width)
2(4w+5) + 2w = 310
8w+10 = 2w =310
10w=300
w=30
30*4=120 120+5=125 l=125
2(125)+ 2(30)= 250+60 =310
Answer:
Always linear...
Decreases with successive trophic level
Answer:
Slope = -1
Step-by-step explanation:
x+y = 14
First convert the equation into slope-intercept form
y = -x+14
Parallel lines have the same slope, so its -1.
Answer:
I tried to answer but I still would like to know what doesn't make sense.
Considering the identity:


The identity is true whenever both sides are defined. It is not supposed to hold the values when we have division by zero, because it is undefined.
If the value doesn't make sense, it is probably not a function, or it is undefined by the given value of
.
Let's go back to the definition of function again:
A function relates a set of inputs and a set of allowable outputs where each input is related to only one output. It basically defines the relation of ordered pairs.
