Answer:
Universal Statements, Conditional Statements,And Existential Statements.

Solve for x.
.9x=9*1 Divide both sides by .9
x=

=10
You would get 10.00 euros.
You can also think of it in this way, that you just move the decimal point over one to the left to get 10.
This is true. It would only be incorrect if dilations were there, because dilations don’t keep the shapes congruent.
A function is one-to-one which means every x-value or member of the domain can only have exactly one output. but, there is no law that says they cannot share an output.
think of it like bridges from inputs to outputs. for it to be a function, there has to be one bridge leaving each input. we dont care where it goes, just that it goes.
You can answer this problem in two different ways: the first being (17 - 5) * x, and the second being 12 * x.
