A) (-1.5, 4)
B) (1.5, 10)
C) (4, -1.5)
D) (-1.5, -2)
Answers
-2x+y=7
4x-y=-4 +
2x+0y=3
2x=3
divide 2
x=3/2
sub
2x-y=-7
2(3/2)-y=-7
3-y=-7
minus 3
-y=-10
negative 1 times both sides
y=10

we know that
It is much easier to compute the number of numbers that do not contain a .
In the first numbers
do not contain a
.
In the first numbers
do not contain a
. (This is because these numbers are formed by selecting a digit out of
for the first position and another digit out of the same set for the last position and this may be done in
In the first numbers, reasoning as above, there are
numbers that do not contain a
.
Now the pattern should be becoming obvious.
In the first numbers there are
numbers that do not contain a
.
So
In the first numbers there are
numbers that do not contain a
.
Thus
the ratio of those numbers that do contain a 3 over the total is equal to
therefore
the answer is
In the first 100 -> 100 - 9 * 9 = 19 (contain a 3).
In the first 10^n -> 10^n - 9^n (contain a 3).
The answer is 3.439 numbers contain a 3 in the first 10.000

given
25^(z - 4) = 125
ln(25^(z - 4)) = ln (125)
(z-4)ln(25) = ln(125)
z = ln(125)/ln(25) + 4
z = 5.5
which means that the answer is A.
The solution of 25^(z - 4) = 125 is equal to a. Z = 5.5
How to solve this equation
25^(z - 4) = 125
From here we have to the ln of the equation
z-4 ln25 = ln125
z-4 (3.219)= 4.828
From here we have to multiply the equation
3.219z - 12.876 = 4.828
3.219z = 4.828 + 12.876
When we divide this equation by 3.219
We have z = 5.499
Hence z = 5.5
Therefore the solution to the equation is given as 5.5
