Which graph shows the solution to this system of linear inequalities? y ≥ 2x + 1
y < -2x - 3

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

If (x-2) 2= 49, then x could be a. -9 b. -7 c.- 2 d. 5 e.9

Can someone factor this fully? my friend and i have two different answers and i would like to know if either of them is right. you in advance. a^2 - b^2 + 25 + 10a
