The options are wrong lol, it is -1/8
Answer:
x = 4 or x = -3
Step-by-step explanation:

Take square both the sides,

x² - x - 12 = 0
x² - 4x + 3x - 3*4 =0
x*(x - 4) + 3*(x - 4)= 0
(x- 4 )(x+3) =0
x -4 =0 or x + 3 = 0
x = 4 or x = -3

Answer:
The current price index number is $604.2.
Step-by-step explanation:
The index value is the ratio between the current value and the reference value, multiplied by 100.
In this problem, we have that:
Current value = $3.48
Reference value: $0.576
Index price = (3.48/0.576)*100 = $604.2.
The current price index number is $604.2.
Answer:
if an equation has the same slope and y intercept the equations will have infinite many solutions. If both equations have the same slope but different y intercept the equations will have no solutions. if both equations are positive or negative and have different slopes and different y intercepts then they will most likely have one solution. (example: y=-2x+3 and y= -4x+4, both slopes are negative so there will be one solution, same goes for if both slopes are positive.
Hope this helps!
