The equation y-4=1 has many solution(s).
Answer:
x ≤ - 2
Step-by-step explanation:
Given the inequality :
3x+5≤−1
Subtract 5 from both sides
3x + 5 - 5 ≤ - 1 - 5
3x ≤ - 6
Divide both sides by 3
3x/3 ≤ - 6/3
x ≤ - 2
Mr.Choe's error was that he changed the inequality sign. The inequality sign in this case does not need to be changed.
-8
Step-by-step explanation:
The gradient or slope of a curve y is simply the derivative of the curve at a point x. So we can proceed as follows

Evaluated at x = 2, the gradient of the slope is
