Solve using linear combination. y + x = –5y – x = 5,a) 0, 5 b) (–5, 0) c) (0, –5) d) (5, 0)

Its worth 10000000 points need asap if you answer correctly ill mark brainliest

Don't know how to find x given these segment lengths

Sketch the region enclosed by the given curves. decide whether to integrate with respect to x or y. draw a typical approximating rectangle and label its height and width. y= 5x, y=7x^2then find the area s of the region.
