susbstitute (-5) for x

anonymous · Answer

So the quation is -4*5-10?

anonymous · Answer

-4*-5-10

anonymous · Answer

oh ok so what now i solve that? would it be 10?

anonymous · Answer

oh ok what about this one? Given the function f(x) = 2(x + 6), find x if f(x) = 22. 

 56 

 5 

 38 

 17

anonymous · Answer

hmm... i think that would be just be 2(22+6)

anonymous · Answer

ok ty and last one :P Given the function f(x) = −2x + 8, find x if f(x) = 14 

 −20 

 36 

 −3 

 −11

anonymous · Answer

yeah, same as the others -2(14+8) think of f(x) being y so sorta like the equation y= -2x+8 if that made any sense

anonymous · Answer

I dont get how to solve that one

anonymous · Answer

im sorry, i wrote the equation wrong i meant -2(14) +8

anonymous · Answer

ok thanks so much!
