Question

Which values for x and y make the statement (x-5)(y + 6)=0 true?
A. x=-5, y=6 B. x=5, y=-6 C. x=-5, y=-6 D.x=5, y=6

Answer 1

@chrisbush put all the values in option in given equation.If they satisfy the given equation, then that option is correct

Answer 2

can you get it what i am saying?

Answer 3

No i dont understand because i was never taught this,im now in a corse recovery program for summer and i came across this awesome website (:

Answer 4

ok.. i will explain you

Answer 5

first take option A, where x=-5, y=6
then put these values in given equation
The given equation is = \(\large (x-5)(y+6)=0\)
so our new equation becomes,
\[\large (-5-5)(6+6)=0\]
now, solve for L.H.S .

Answer 6

@chrisbush

Answer 7

Okay (: now how do i solve the rest of the new equation?

Answer 8

lol.. just like as option A . Only you need to do is that take different options like A,B and C.
And solve for L.H.S and if any option's L.H.S is zero then that option is correct answer.

Answer 9

ok.. @chrisbush i hope you understand

Answer 10

(-5-5)(6+6) = 0 is not true because (-5-5)(6+6) = -10*12 = -120 != 0
so this is not a solution, so not try the next

Answer 11

Lol im so confused D; i dont know the answerrr

Answer 12

lolzz.... @chrisbush try again and again as @zzr0ck3r said

Answer 13

notice if you put in x = 5 then the whole thing is 0
notice if you put in y = -6 then the whole things is 0
so pick the one/ones that have either x=5 or y=-6 or both

Answer 14

note: 0*anything = 0

Answer 15

so it would be b?

Answer 16

yes!!!

Answer 17
