Determine if the equation x - ya = 1 defines y as a function of x.
no. at least one input results in more than one output.
yes. one input results in one output.
no. at least one output results in more than one input.
yes. one output results in one input.

  Yes. One input results in one output.

Step-by-step explanation:

If "A" is not dependent upon x or y, this is a linear equation. Any linear equation in two (or more) variables defines a function.

Yes, this equation defines a function.

__

A function has one output for each input. The appropriate description is the one shown as the Answer.

0.84 dang lotta people are looking for this lol or if you round up its 1 but the overall answer to that is 0.84

step-by-step explanation:

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
