We know |x| ≥ 0 for all real numbers. Therefore your answer is x ∈ ∅ (no solution).
1 x 2 x 2 x 2 x 3 x 3 x 7
Answer:
Step one identify the two points on the line in the graph
Example: (0,2) ( 2,1)
Step two calculate the vertical change from one point to the next
Step three write the ratio vertical change over horizontal change
Example (-1/2 )
Answer:

Step-by-step explanation:
Answer: 6+4x=26, 4x=20
Step-by-step explanation: 6+4x=20 is the initial equation but completely multiplied by two, so you can know without solving that it is equivalent.
If you solve the equation, 2x+3=13 (subtract 3 from both sides)
2x=10 (divide both sides by 2)
x equals 5.
if you plug in 5 as x to 4x=20, you get 20=20, which is a true statement, so this choice is also correct. You could also solve to prove x equals 5 in this equation as well. Divide 20 by 4 and you get x=5.
