We know that 5x-3x =2x
So x(5x-3x)=x×2x
=(2x)^2
=4x^2
Which is given as 18.
X^2=18÷4
=4.5
So x=root over 4.5
Which is approximately 2.25
Step-by-step explanation:
The vertex is the point (-4, 7).
Answer: 1406
Step-by-step explanation:
Given Table :
Admissions Probability
1,040 0.3
1,320 0.2
1,660 0.5
Now, the expected number of admissions for the fall semester is given by :-

Hence, the expected number of admissions for the fall semester = 1406
Answer: 3
Step-by-step explanation:
Given :
343
We need to write 343 in index form of 7.
343 is the same as
, replacing 343 with
, we have

Recall one on the law of Logarithm :

can be written as c
b
So,
can be written as ;
3
7
Also from the laws of Logarithms ,
a = 1
so , Log_{7}[/tex] 7 = 1
The solution then becomes
3 x 1 = 3
Therefore :
343 = 3
Answer:
Step-by-step explanation:
It is any number that is 3 or less
