I rounded the answer I got which is 1.6 or 1.60
Answer:
)
Step-by-step explanation:
This system we can solve by substitution method :
y=13x-1
y=9x+4
_______
y=13x-1
13x-1=9x+4 (instead y in second equation we use 13x-1 and first rewrite)
_______
y=13x-1
13x-9x=4+1 (subtract 9x and add 1 for each side)
______
y=13x-1
4x=5 (divide by 4)
_____
y=13x-1
(instead x in first eq we write 5/4)
______

Answer:
21,600
Step-by-step explanation:
If in the coding system being used there are 6 vowels (A, E, I , O, U and Y)
Number of Consonants =26-6 =20
- First entry must be a consonant, therefore the first entry can be chosen in 20 ways.
- The second entry must be an integer 1 through 9, therefore the second entry can be chosen in 9 ways.
- The third entry must be one of the six vowels, therefore the third entry can be chosen in 6 ways.
- The last entry must be a consonant, therefore the last entry can be chosen in 20 ways.
Therefore:
Number of different possible ciphers =20*9*6*20
=21600
Answer:
The slop of line perpendicular to line y =
x - 2 is ( - 3)
Step-by-step explanation:
Given Line equation as ,
y =
x - 2
The equation of line is y = mx + c
Slop of this line (m1) = 
Now second line with slop (m2) is perpendicular to line first , then
(m1) × (m2) = - 1
So, (m2) =
Or , (m2) = 
∴ (m2) = - 3
Hence the slop of line perpendicular to line y =
x - 2 is ( - 3) Answer
X/3=8/12
x/3=2/3
x=2
The answer is C
