PLEASE HELP IM SCARED! I clicked on one of those xtiny. cf links and pressed download and now I heard that it’s a virus??? What do I do?!?!

F(x)=|x| is shifted down 4 units and to the right 3 units.

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]

Give the equations of two different lines that are perpendicular to the line 3x + 4y = 7.
