Answer:
Step-by-step explanation:
-31
You first substract 18 from both sides so you get
10x<-20 you then divide by 10 so the answer is
x<-2
One of the fractions could be 1/2
Hoped this helped at all :)
Answer:

Step-by-step explanation:
Well since in,

the 3x^2is negative that means the parabola has a maximum not a minimum meaning we can take out choices,
B and D.
To find the maximum let’s graph the given equation,
Look at the image below.
By looking at the image we can tell that the maximum is at (1,1).
So the answer is choice A (1,1)
Answer:
The idea is to transform the expression by multiplying
with its conjugate,
.
Step-by-step explanation:
For any real number
and
,
.
The factor
is irrational. However, when multiplied with its square root conjugate
, the product would become rational:
.
The idea is to multiply
by
so as to make it easier to take the limit.
Since
, multiplying the expression by this fraction would not change the value of the original expression.
.
The order of
in both the numerator and the denominator are now both
. Hence, dividing both the numerator and the denominator by
(same as
) would ensure that all but the constant terms would approach
under this limit:
.
By continuity:
.
