Answer:
Option D) c = 100, a = 50, s = 20
Step-by-step explanation:
we have
6c + 7a + 2s = 990 -----> equation A
3c + 3a + 4s = 430 -----> equation B
2c + 4a + 4s = 480 ----> equation C
Isolate variable s in equation A
2s = 990 -6c-7a
s=495-3c-3.5a -----> equation D
Substitute equation D in equation B and in equation C
3c + 3a + 4(495-3c-3.5a) = 430
3c + 3a +1,980-12c-14a= 430
-9c-11a=-1,550 -----> equation E
2c + 4a + 4(495-3c-3.5a) = 480
2c+4a+1,980-12c-14a=480
-10c-10a=-1,500 -----> 10c+10a=1,500 -----> equation F
Solve the system of equations E and F by graphing
using a graphing tool
Let
The variable c -----> the x-axis
The variable a ----> the y-axis
The solution is the point (50,100)
see the attached figure
so
c=50, a=100
Find the value of s
s=495-3(50)-3.5(100)=-5 -----> is not make sense
therefore
Let
The variable c -----> the y-axis
The variable a ----> the x-axis
The solution is the point (50,100)
so
a=50, c=100
Find the value of s
s=495-3(100)-3.5(50)=20
therefore
The solution is
c=100,a=50,s=20
Given:
The two functions are:
To find:
The type of transformation from f(x) to g(x) in the problem above and including its distance moved.
Solution:
The transformation is defined as
.... (i)
Where, a is horizontal shift and b is vertical shift.
- If a>0, then the graph shifts a units left.
- If a<0, then the graph shifts a units right.
- If b>0, then the graph shifts b units up.
- If b<0, then the graph shifts b units down.
We have,
The function g(x) can be written as
...(ii)
On comparing (i) and (ii), we get
Therefore, the type of transformation is translation and the graph of f(x) shifts 2 units up to get the graph of g(x).
<u><em>16.1 is the final answer. </em></u>
<em>Product- it's going to be multiply by the numbers only.</em>
<em>You can also round up to the nearest tenths is 16.0</em>
