Write the number 4,520,000 in scientific notation.
4.52 × 10^6

Explain why substituion might be the better method than elimination for solving.
y=3x+1
x+y=10
Subnstitituion is preferred because one equation is already solved for y, making it easiy to suybsitute.

Describe the conditions under which a system of linear equations has no solutions.
A system of linear equations has no solutions if the lines represented by the equations are parallel, they have the same slope but never interesect.
