Answer:
all real numbers expect 1.
Step-by-step explanation: This is a rational function. when we usually the find the domain of a rational function we would look at the bottom because you don't want the denomonatior to be zero because dividing by zero in math makes the range undefined. so we use the equation and set it up to zero to find the domain. 1-x=0 -x=-1, divide by -1 and we get 1. So x can be any numbers expect 1. Interval notation: (-∞,1)∪(1,+∞)
Answer:
5x²(2y + 5)
Step-by-step explanation:
10x²y + 25x²
to start we have to express the parts of the function as multiplication
2*5*x²*y + 5*5*x²
then we have to see that they have both parts of the sum in common, and what they have in common we get out of common invoice and what is left we add together.
5x²(2y + 5)
Okay so the problem starts you off with the fraction (1/4). Sharing equally among 3 people would mean that you'd want to divide it by three so your equation would initially look like (1/4) / 3. Having two dividing signs is confusing so what you do is change the dividing into multiplying by the reciprocal of 3 = 1/3... This would make your expression (1/4) * (1/3) and when you simplify this you should get 1/12 as the answer.
Change 30 hours into minutes, then divide by 20 and 25
