4x+12=16
4x=4
x=1
or
-(4x+12)=16
-4x-12=16
-4x=28
x=-7
answer Choice C is correct
Answer: 42.6% or you can round it to 43%
Step-by-step explanation:
The mean absolute deviation of the data set is 4
Linear combination method just means to add the equations so that one variable with cancel. In this case the a values are already set up so that they will cancel.
2a + 3b = 1
-2a + b = 11
4b = 12
b = 3
now put 3 back into either of the original equations and solve for a.
2a + 3(3) = 1
2a + 9 = 1
2a = -8
a = -4
(-4,3)
Answer:
Any value of x makes the equation true.
Step-by-step explanation:
all real numbers
interval notation:(-infinity, infinity)
