Answer:
The input is 1/7
Step-by-step explanation:
If y =f(x)
Given that f(x) = -7x -2, then y = -7x-2
x is the input
y is the output
Given the output y = -3, we are to find the input value x
Recall that y = -7x-2
On substituting the value of y into the equation
-3 = -7x - 2
-7x = -3+2
-7x = -1
x = -1/-7
x = 1/7
Hence the input is 1/7
It would be a horizontal line (dotted line) at the y intercept 3. Make a line 3 units up, and it is dotted. Shade below the dotted line, to show the "less than" part. Hope this helps
Answer: x=6
Step-by-step explanation:
3(5-2x)-3x=3
-15+6x-3x=3
-15+3x=3
3x=3+15
3x= 18
x=6
