Solve for x in X-2 (x=8)
Substitute X=8 into 3x - 6y =18 (24-6y=18)
Solve for y in 24-6y=18 (y=1)
X=8 and y=1
Answer:
The parameters in the parent function are:
- the parameter correspondig to - 3 in the given function is 0 in the parent function.
- the parameter corresponding to 1/2 in the given function is 1 in the parent function, and
- the parameter corresponding to - 1 in the given function is 1 in the parent function.
Explanation:
The given function is 
.
The parent function of 
. The parameters of the given function are -1 (which is mutlyplying the value of cosine, 1/2 which is multiplying the argument (x), and - 3 which is subtracted.
In the parent function, those values are 1, 1, and 0.
It may help you representing the parameters in the given function with letters:
Then, in the given function A = - 1, B = 1/2, and C = -3.
Now, you can write the parent function:
Then, the parameters are A = - 1, B = 1, and C = 0.
Answer:
If you draw this out, you can see that total fence equation will be:
2L + 4W = 1200
Simplify, divide by 2
L + 2W = 600
L = (600-2W)
:
Area;
A = L*W
Substitute (600-2W) for L:
A = (600-2W)*W
A = -2W^2 + 600W; a quadratic equation
:
The dimension that will produce the greatest area will be the "axis of symmetry
which is: x = %28-b%29%2F%282a%29
:
In this equation a=-2, b=600
W = %28-600%29%2F%282%2A-2%29
W = %28-600%29%2F%28-4%29
W = +150 ft is the width
:
Find the length
L = 600 - 2(150)
L = 300 ft is the length
:
We can say the a field 300 by 150 gives he greatest area
:
This illustrated on a graph where y axis is the area and x axis is the width:
Step-by-step explanation:
1.x=c-h
2.h=w/g
3.a=k+b
4.r=kw
