Answer:
The inverse of f(x)=3x+1 is f(x)−1=13x−13
Step-by-step explanation:
The basic form of linear function is
y=ax+b
For finding the slope, use the slope formula.
(4-2)/(-2+1)= 2/-1=-2
We first found a which is -2.
Then insert any point to find the value of b. In this case, I will insert (1,-2).
-2=-2+b
b=-2+2=0
The linear graph is y=-2x
Answer:
yes, it makes the inequality true
Step-by-step explanation:
Try it and see.
x - 5y < 7
-3 -5(2) < 7
-13 < 7 . . . . . . true
The given point is a solution.
