I need help with geometry i suck at it very bad

Farnesene is a sesquiterpene. how many different isomers arising from double-bond isomerizations are possible? g

Which of the following equations is of the parabola whose vertex is at (4, 3), axis of symmetry parallel to the y-axis and focus at (4, -3)? a.) y+3=1/24 (x+4)^2 b.)y-3=-1/24 (x-4)^2 c.)x-4=-1/24 (y-3)^2

Find the solution set of this inequality. enter your answer in interval notation using grouping symbols. |8x-4| ≤ 12
