Answer:
x=[15:-5:-25]'
Step-by-step explanation:
In order to create a vector you need to use this command:
x = [j:i:k]'
This creates a regularly-spaced vector x using i as the increment between elements. j is the initial value and k is the final value. Besides you need to add the character ' at the end in order to convert the arrow vector in a column vector
2x -4y=20
-4y=-2x+20
Y= 1/2x - 5 that’s the answer
34/85%=34/0.85=40
So that's your answer.
