Solve the system of equations 4x - 9y = 5 and 8x - y = - 7 by combining the equations.

Ac contractor is building a new subdivision outside of the city. he has started work on the first street and is planning on the other streets to run in a direction parallel to the first. the second street will pass through (-2,4) find the equation of the location of the second street in standard form. a.2x+y=2 b. x-y=2 c.2x+y=2 d. x+y=2

F(x)=x/2-2 and g(x)=2x^2+x-3 find (f+g)(x)

Write the point-slope form of the line passing through (2, -12) and parallel to y=3x.
