Gas prices have slowly increased in the past 3 weeks. They are now at $2.68. 3 weeks ago, gas prices were at 2.41. To the nearest percent, what is the percent increase in gas prices?

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)

step-by-step explanation:

set the two equations for y equal to each other. solve for x. this will be the x-coordinate for the point of intersection. use this x-coordinate and plug it into either of the original equations for the lines and solve for y.
