Hello out there,I need some help with some problems,
the first one is,Solve the inequality:
>
Multiply both sides by -3, and since we are multiplying
by a negative number, we turn the symbol > around and
make it < instead:
<
Multiply on the left to get -54, and
cancel the -3's on the right, and we
have
<
This can also be written as
>
for if -54 is less than x, then
x is greater than -54
.The next one is,Solve the inequality:
d/-2<-4.
<
Multiply both sides by -2, and since we are multiplying
by a negative number, we turn the symbol < around and
make it > instead:
>
Cancel the -3's on the left and multiply on the
right to get 8, and we have
>
The third one is,Solve the inequality:
Divide both sides by -6, and since we are dividing
by a negative number, we turn the symbol > around and
make it < instead:
<
Cancel the -6's on the left and divide on the
right to get -6, and we have
<
And the last one is, Solve the inequality:
10 < y - 4
Add +4 to both sides:
10 + 4 < y
14 < y
We do not turn the symbol around unless we are
multiplying or dividing by a negative number.
However this can be written as
y > 14
because if 14 is less than y, then y is greater
than 14.
