Which is the best first step when solving the following system of equations? y= 7x+3 y=9x

Write the sine and cosine values of a, b, respectively, in the figure for (1) and (2) + explanation.

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

Which spreadsheet would be used to compute the first nine terms of the geometric sequence a^n=32•(1/2)n-1
