I believe it is 3. since it touches the x-axis in three areas
Step-by-step explanation:
Put the values of x = 6, y = -7 and z = 0.8 to the expressions:
a) 5x → 5(6) = 30
b) 3y → 3(-7) = -21
c) 10z → 10(0.8) = 8
The solution to the equation includes both the positive and negative portions of the solution. x = 12, -12
Answer is 150/x see photo for solution
