Evaluate the algebraic expression d - b when b = 3, d = 12, h = 2 and r = 7.

(08.01)consider the following pair of equations: x + y = −2 y = 2x + 10 if the two equations are graphed, at what point do the lines representing the two equations intersect? (−4, 2) (4, 2) (−2, 4) (2, 4)

Which is the equation of a line perpendicular to the line with the equation 3x+4y=8

Im literally having a mental breakdown
