2x-57 degrees = -55
In Roman numerals the symbol "X" means 10.
There's no way we can figure that out until you tell us how 'x' and 'y' are related to each other. That kind of information is called an "equation".
y is a function of x iffor each value of x (in the domain) there is a value of y, andfor each value of y (in the range) there is at most one value of x.
if a function has a unique y value for each x value the function is one to one.
X is an unknown quantity. You would need the rest of the equation to figure out the value of X.
Starting from the right, and working left - each digit is 8 times the value of the preceding one. So - in this example...The figure 3 remains the same.The figure 4 is 8 x 4... 32The figure 2 is 8 x 8 x 2... 128So... 3+32+128=163
Any equation which maps each value of x in the domain to a value in the range is a function of x.
Any equation which maps each value of x in the domain to a value in the range is a function of x.
There are infinitely many. For each value of x there is a value of y, and there are an infinite number of values of x to start with.
A set of ordered pairs that assign to each x-value exactly one y-value is called a function.
each time you add 1 to x the value goes up by one for example if x=2 then 5+2=7 but if you add 1 to x and x=3 then 5+3=8
