What is the length of ? Round to the nearest tenth. 9.7 m 10.4 m 37.3 m 38.6 m

X+ y = k 2x + 3y = k + 1 the point of intersection of the lines has an x-coordinate of a.2k + 1 b.-2k + 1 c.2k - 1

Use the inverse of the function y=x^2-18x to find the unknown value [tex]y = \sqrt{bx + c \: + d} [/tex]

Can someone me and plz do the problem
