Nina knows that the average of the x-intercepts represents the line of symmetry for a quadratic function through the x-axis. which equation represents the average of the x-intercepts for f(x) = 4x2 β 24x + 20? startfraction negative 5 minus 1 over 2 endfraction = negative 3 = β3 startfraction negative 10 minus 2 over 2 endfraction = negative 4 = β4 startfraction 1 + 5 over 2 endfraction = 3 = 3 startfraction 2 + 10 over 2 endfraction = 4 = 4

Arianna is buying plants for her garden. she buys 15 flowering plants for $96. pink flowering plants sell for $8, and purple flowering plants sell for $5. how many pink flowering plants did arianna buy? i figured out the answer! the answer is 7. 8x +5y = 96 plug in 7 for x 8 (7) + 5y = 96 56 + 5y = 96 subtract 56 from both sides 5y/y = 40/5 y = 8 she bought 7 pink and 8 purple plants
