Question

Which of the following is the additive inverse of -4b?

4b

-4b<----my answer

1/4b

-1/4b

Which values for x and y make the statement (x + 5)(y - 6) = 0 true?



x = 5, y = -6


x = 5, y = 6


x = -5, y = 6


x = -5, y = -6

Answer 1

additive inverse of x is -x
that is we just switch the signs

so additive inverse of -4b will be??

Answer 2

opps i meant i chose A my mistake

Answer 3

when a+b = 0
we say a=-b

when pq = 0, we say
either p=0 or q=0

so,
when (x+5)(y-6) =0

we say
x+5 = 0 or y-6 = 0

x+5 = 0
just subtract 5 from both sides, what do u get?

y-6 =0
just add 6 on both sides, what do u get?

Answer 4

so x= -5 and y= 6?

Answer 5

yes, 4b is correct for the 1st one

and x=-5, y= 6 is also correct!
good :0

Answer 6

thank you cx

Answer 7

Which values for a and b make the statement (a - 2)(b + 3) = 0 true?

a = -2, b = 3

a = 2, b = 3

a = -2, b = -3

a = 2, b = -3

Answer 8

is the answer to this question D?

Answer 9

yes, D is correct :)

Answer 10

ok thank you again cx
