Solve the system
4x+5x= -27
x+9y= 1

Aline has a slope of 1/4 and passes through point (0.4,-1/2). what is the value of the y-intercept?

What is the value of x in the diagram below?

Select the correct answer from the drop-down menu. subtracting 3xy^2 from 8xy^2 gives the same result as the expression. [tex]3xy ^{2} - 8xy ^{2} [/tex][tex] { - 7xy}^{2} - {2xy}^{2} [/tex][tex] {7xy}^{2} - {2xy}^{2} [/tex]
