Let roses be R and carnations be C
"in a ratio of 2 to 7" means that the ratio of R to C is 2 to 7, meaning you'll have to cross multiply to translate it algebraically
since C = 343 we plug 343 in :
ergo, she needs 98 roses
to make sure of the answer:
"ratio of 2 to 7" is technically a fraction =>
and since the ratio of the roses to the carnations is the same as we plug the values R = 98 and C=343:
check with calculator too, hope i helped <33
Domains of functions are the values that <em>can</em> be plugged into the function and not "break" it. By "break" I mean that the denominator cannot be 0, in this case. If the denominator is 0, we will get a divide by 0 error, and thus, we must restrict the domain. All values of x will work except 9/4:
Let's plug in 9/4 and see what happens:
So, plugging in 9/4 results in denominator equalling 0. Therefore, we must restrict the domain so that x ≠ 9/4. Your answer is All real values of x such that x ≠ 9/4.
