1. Find x and y

Many thanks!

Astrid spent $36 on new shoes. this was $12 less than twice what she spent on a new skirt. part a: which equation would solve for how much she spent on the skirt? part b: solve the equation in the workspace provided below. how much did astrid spend on her skirt?

X² + 4y² = 36 the major axis runs along: a) y=4x b) x-axis c) y-axis

How many and of which kind of roots does the equation f(x)=2x^4−9x^3+17x^2−16x+6 have?
