In your situation you said that
Putting those together, you'd have 
because 
.
To evaluate the difference quotient, first find each piece on it's own:
because 
no matter what your x-value is.-
So putting those together:
Remember that the difference quotient is basically finding the slope of something. Since you were given that the slope is 0, the difference quotient should work out to match that.
In standard form the two equations are
7x +y = 5
7x +y = -5
The equations describe lines that are parallel.
Answer:
Step-by-step explanation:
<u>Use identities to set the equation up as a quadratic</u>
<u>Make the substitution u=cos(x) and solve the quadratic</u>
<u />
Hence,
By definition the area of a rectangle is:
A = w * l
The perimeter is:
P = 2w + 2l
Where,
w: width
l: long
Substituting values:
300 = w * l
80 = 2w + 2l
Solving the system of equations we have:
l = 30 m
w = 10 m
Answer:
The length and width of the field are:
l = 30 m
w = 10 m
Answer:
the answer would be x = 3, 0
Step-by-step explanation:
as much as I would like to, I'm really not that good at explaining things
