PLEASE HELP. It is discovered that the college registration process for Professor Smith's Calculus class can be modeled by the equation
y=2x+12, where y = the number of students registered at the end of each day, and x = the day of registration. Professor Smith has 12 students pre-registered before the registration process begins, and the registration closed after 7 days.
While it can be said that y=2x+12 models the registration process for this Calculus class, you can see that the "real" model is only a portion of this straight line. There are no "negative" days for the registration process, and there are no days beyond Day 7 for registration.

Ответ:
Given that we Jenny wants to equivalent fraction of 45% then convert into reduced fraction and then convert into decimal equivalent.
She has already shown her work. We just need to find the error if any.
to convert any percent value we just divide that number by 100 because percent itself means divide by 100.
Hence first step 45%=45/100 is correct.
Then she needed to convert into reduced fraction. To do that she divided numerator and denominator both by 5 and got 9/20.
step 2 is also correct.
Now she needs to convert into decimal equivalent so she divided 9 by 20 and got 4.5 while the correct answer should be 0.45
Hence she did error when converting fraction form into decimal form.
