2. Presley graphed a system of equations, and the graph showed two parallel lines. What does this mean? A. The system of equatio
ns has one solution. B. The system of equations has no solution. C. The system of equations has infinitely many solutions. D. Presley made an error in her graphing.
Parallel lines never touch, in order for a system of equation to have a solution the two equations have to intersect, because parallel lines never intersect the system of equations that Presley graphed would have no solution
The second one: 3^7 x 3^(86/10) x 3^(9/1000) That is because when you multiply powers with the same base ( in this case they are all 3), you just leave the base as it is and add the exponents so it is basically 3^(7 + 86/100 + 9/1000) which is 3^7.869
⇒ Ten to the third power
⇒ Ten to the fifth power
