Question

Which values for x and y make the statement (x + 4)(y - 1) = 0 true?

x = -4, y = 1

x = -4, y = -1

x = 4, y = 1

x = 4, y = -1

Answer 1

the product of 2 numbers is 0 if either of the two is 0 or if both are zero
so we have - (x + 4)(y - 1)
the product can be zero if x+4 becomes 0
so x+4= 0
so x=-4
the product can become 0 when y-1=0
so y=1

so 1st option is correct :)

Answer 2

oh ok tysm!

Answer 3

welcome :D

Answer 4

Which values for x and y make the statement (x - 3)(y + 8) = 0 true?

x = -3, y = 8

x = 3, y = 8

x = 3, y = -8

x = -3, y = -8

for this one would my answer be c?

Answer 5

yes :)

Answer 6

ok thnx!

Answer 7

no problem :D
