We have the expression:
When we have rational functions, where the denominator is a function of x, we have a restriction for the domain for any value of x that makes the denominator equal to 0.
That is because if the denominator is 0, then we have a function f(x) that is a division by zero and is undefined.
If we have a value that makes f(x) to be undefined, then this value of x does not belong to the domain of f(x).
Expression:
Answer: There is no restriction for x in the expression.
Answer:
55.55%= boys & 44.44% = girl
Step-by-step explanation:
1000/(1000+800)=1000/1800=.5555 or 55.55% are boys
800/(1000+800)=800/1800=.4444 or 44.44% are girls.
Therefore, 55,55% are boys and 44.44% are girls.
Answer:
1/2 lb
Step-by-step explanation:
(1)1.75 + 3(3.75) - 4 = 23.5/4
23.5x/4 = 2.95
23.5x = 11.8
x = 0.5
What if I write the equation like this:
y = zero x - 3.
Now you know that the slope of the line is zero and its y-intercept is -3.
That's a horizontal line that crosses the y-axis at -3. And just like the equation says, the value of 'y' doesn't depend on 'x'. It's -3 everywhere.
The answer should be A and D
