Question

Which number is a solution of the inequality? HELP
x(7 – x) > 8
2
-1
0
8

Answer 1

replace the x's with 2's
and see if the inequality holds true

Answer 2

then do the same until you find one that makes the inequality true

Answer 3

like for example
enter in 2
2(7-2)>8
is this true is 2(7-2) greater than 8?

Answer 4

substitute the variable with the number

Answer 5

i THINK ITS a .... am i right

Answer 6

is that because you think 2(7-2)=2(5)=10 is greater than 8
if so yeah
it happens to be the first choice we tried

Answer 7

yes i think thats it!

Answer 8

the other choices won't work
if we enter in -1 for x
we see that
-1(7-(-1))=-1(8)=-8
and -8>8 is definitely not true
trying x=0
0(7-0)=0
0>8 not true
and then so on..
