Answer:
a. 2n = 3n − 12, 12
Step-by-step explanation:
Let the number be represented by n.
Then 2 times the number is 2*n = 2n
3 times the number = 3*n = 3n
12 minus 3 times the number is 3n-12
It is given that 2 times the number is the same as 12 minus 3 times the number.
Expressing this equation form:
![\[2n=3n-12\]](https://tex.z-dn.net/?f=%5C%5B2n%3D3n-12%5C%5D)
Solving the equation,
![\[3n-2n=12\]](https://tex.z-dn.net/?f=%5C%5B3n-2n%3D12%5C%5D)
![\[=> n=12\]](https://tex.z-dn.net/?f=%5C%5B%3D%3E%20n%3D12%5C%5D)
Hence the required number is 12.
Yes, the equation specifies a function with independent variable x.
Equation: 6x + 19y = 7
This can be put in y = mx + b form,
6x + 19y = 7
19y = -6x + 7
y = -
x + 
Since the equation can be put in the form of a linear function, the domain is all read numbers (-∞,∞) or -∞ < x < ∞ .
Answer
4(y - 6)
Explanation
The difference of y and 6 can mathematically be represented as y - 6.
Therefore, four times the difference of y and six will be 4(y - 6).
1). 8 x 5x - 8 x 3y
40x - 24y
you have to multiply the eight inside the parentheses
3x+22.5 = 69.75
-22.5 -22.5
3x = 47.25
/3 /3
x = 15.75
