Answer:
slopes is the ratio of the change in the y value over the change in the x value
I really suck at problem solving check the options
Answer:Brian got 1.75 lbs of rice per dollar.
Step-by-step explanation: easy way to do these problems is just dividing!! 7 divided by 4 is 1.75. How to double check? Just simply times 1.75 by 4 and you’ll get 7:)
Answer:
domain: (-∞, ∞)
Range: [4, ∞)
Step-by-step explanation:
Domain is all of the values of x that satisfy the equation. You can find this by looking for any asymptotes, or just any value that f(x) does not exist. If you simply think if this as a graph, the function continues for all real numbers. Therefore, domain: (-inf, inf)
As for range (the y values of the function), we need to know if there are any horizontal asymptotes, or y-values that y does not exist. We can tell that the function starts at 4. There is no value >4 that does not satisfy the equation, so range: [4, inf)
