Answer:
Subtracting −7n+2 from 2n−1 is 9n - 3.
Step-by-step explanation:
As the expression given in the question be as follow.
−7n+2 and 2n - 1 .
Subtracted −7n+2 from 2n - 1 .
= 2n - 1 - (-7n + 2)
Open the bracket
= 2n - 1 + 7n - 2
Simplify the above
= 9n - 3
Therefore Subtracting −7n+2 from 2n−1 is 9n - 3.
Answer:
x=5, y=-3, x=-4, y=9
Step-by-step explanation:
1. x=5, is a vertical line cutting the x axis at 5
2. y=-3 is a horizontal line cutting the y axis at -3
3. x= -4, is a vertical line cutting the x-axis at -4
4. y=9, is a horisontal line cutting the y-axis at 9
