Answer:
The given expression can be written as -1=19(-1)+18.
Step-by-step explanation:
According to quotient remainder theorem:
For any integer a and a positive integer d, there exist unique integers q and r such that
It can also written as
The given expression is
Here a=-1 and d=19.
If -1 is divides by 19, then the remainder is 18. The value of r is 18.
Therefore the given expression can be written as -1=19(-1)+18.
Answer:
In general, we determine the domain of each function by looking for those values of the independent variable (usually x) which we are allowed to use. (Usually we have to avoid 0 on the bottom of a fraction, or negative values under the square root sign).
The range of a function is the spread of possible y-values (minimum y-value to maximum y-value)
Substitute different x-values into the expression for y to see what is happening. (Ask yourself: Is y always positive? Always negative? Or maybe not equal to certain values?)
Make sure you look for minimum and maximum values of y.

Answer:
Inequality
x+35=56
Step 1: Subtract 35 from both sides.
x+35−35=56−35
So the answer is 21.
Step-by-step explanation:
Answer:
x = 60
Step-by-step explanation:
80/ 4+x = 16
(4 + x) * 80/ 4+x = 16 = 16 (4 + x)
80 = 16 + 4 + x
80 = 20 + x
60 = x or x = 60
