Please help solve with step by step process.

3x + 4.7 < -1.5x + 6.5

Solve the equation using the given values: x= -2.5; y= -7.51. 2xy + 2x²

Which expression can be used to determine the slope of the line that passes through the points -6, three and one, -9

To solve the system of equations below, grace isolated the variable y in the first equation and then substituted into the second equation. what was the resulting equation? 3y=12x x^2/4+y^2/9=1
