Answer:
Domain: ( -∞ , ∞ )
Range: ( -∞ , 4 ]
Step-by-step explanation:
Hi there!
The domain tells us the possible x-values of a function. Because there are arrows at the end of each side, it means the graph is travelling infinitely to both the left and the right side. This means the the domain is all real numbers, meaning that for any value of x, there is a real value for y.
( -∞ , ∞ )
The range tells us the possible y-values of a function. Both sides of the graph are travelling infinitely downwards, starting from 4.
( -∞ , 4 ]

Answer:
The product of a rational number with an irrational number is an irrational number. To see this assume that x is a rational number and y an irrational number. Then let us assume that the product xy is rational, which means that there are integers a,b such that xy=a/b. But then we obtain y=(1/x)(a/b) which is also rational since the set of rational numbers is closed under multiplication. But this is a contradiction since y was assumed to be an irrational number.
Step-by-step explanation:
Question:Now consider the product of a nonzero rational number and an irrational number. Again, assume x =a/b , where a and b are integers and b ≠ 0. This time let y be an irrational number. If we assume the product x · y is rational, we can set the product equal to m/n, where m and n are integers and n ≠ 0. The steps for solving this equation for y are shown. Based on what we established about the classification of y and using the closure of integers, what does the equation tell you about the type of number y must be for the product to be rational? What conclusion can you now make about the result of multiplying a rational and an irrational number?
Answer:2
Answer:
31 students will be going on the trip.
Step-by-step explanation:
Create an equation.
60x+40x+30x=4030
Combine like terms.
130x=4030
Divide.
x=31
Checking solution...
60(31)+40(31)+30(31)=4030
1860+1240+930=4030
4030=4030
