Whats the domain for this equation?

Strictly speaking an equation does not have a domain. A function does. Though it may make sense to speak about a solution set to this equation over a domain.

The following could be helpful towards an The equation has two sides. The left hand side is a non-linear function and the right hand side is a line with slope -1 and y-intercept of 1.

The function has a domain over all Reals x for which it holds so the domain of the nonlinear function is .

The domain of the linear function 1-x is all Reals:

So, together you could say the equation's solutions are defined over the domain .

Lmk if you have questions.

sorry can't

step-by-step explanation:

i googled though and something came up but it was in science langueage not common english sooo

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
