The value of x is
-4x + 8 = 42
-4x = 42 -8
-4x = 34
x = -8,5
6.5 is the answer to your question

Answer:
y = -1/2x + 3
Step-by-step explanation:
It can work to start with the 2-point form of the equation for a line.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (1 -5)/(4 -(-4))(x -(-4)) +5 . . . . . fill in point values
y = -4/8(x +4) +5 . . . . . . . . simplify a bit
y = -1/2x -2 +5 . . . . . .eliminate parentheses
y = -1/2x +3 . . . . collect terms
sqrt(81) = 9
sqrt(100) = 100
sqrt(92) is between 9 and 10.
Answer: 10
