I want a way to solve such a problem

For f(x)=2x+3 and g(x)=x^2- 8 find (f+g) (x)

Ialready asked this but i never got an answer. will give a high rating and perhaps brainliest. choose the linear inequality that describes the graph. the gray area represents the shaded region. y ≤ –4x – 2 y > –4x – 2 y ≥ –4x – 2 y < 4x – 2

Find the slope of the line that passes through the points (0, 0) and (-2, -3). 2/3 3/2 -3/2
