<em>The proper format for scientific notation is a×10ᵇ where </em><em>a</em><em> is a number or decimal number such that </em><em>the absolute value of a is greater than or equal to one and less than ten or, 1 ≤ |a| < 10</em>
As we see 17.4 > 10 which is against the rule above
To have infinitely many solutions, the lines must be identical consisting of exactly the same points to make it. This means when in simplest form their equations are the same as well.
Simplify 2x+2y=8 by dividing by 2 throughout the entire equation. It becomes x+y = 4. This equation matches B.
