X ∈ (real numbers symbol not in brackets) : 0<x<17.89 and 18.61<x
Absolute value is alwas positive
so all of them excet the 3rd one are false
|w|=0 has 1 solution
if the last one was |w|=1 then ther would be 2 solutions, -1 and 1
answer is |w|=0
MAB = 110
mACB = 360 - 110 = 250
hope it helps
Answer: y= -2x + 24
Step-by-step explanation
2x - 4y = 24
subtract 2x from both sides
divide 4y by 4y to get y by itself
then you get y= -2x + 24
Multiply the first equation by 3 and the second equation by 2:
Subtract the two equation to get rid of the x variable:
Use the value of y to determine the value of x: for example, using the first equation we have
