Answer:
8w + 3
Step-by-step explanation:
4(5w +3) - 2(w - 1) =
= 20w + 12 - 2w + 1
= (18w + 13) / 10 = 8w + 3
Given Equations
- 5x+3y=8--(1)
- 4x+7y=34--(2)
Let it has solution (x,y)
Add both
It will also have same solution (x,y)
#1) (b)
#2) (d)
#3) (d)
My explanations are the same as your previous questions.
Given:
The function is:
To find:
The inverse of the given function, then draw the graphs of function and its inverse.
Solution:
We have,
Step 1: Substitute .
Step 2: Interchange x and y.
Step 3: Isolate variable y.
Step 4: Substitute .
Hence, the inverse of the given function is and the graphs of these functions are shown below.
