The unit rate in the equation is 20.
Option C) is the correct answer.
<u>Step-by-step explanation</u>:
Step 1 :
In the given equation y = 20x
where,
x ⇒ total number of hours for tutoring
20 ⇒ the cost per hour of tutoring
y ⇒ the total cost for total hours of tutoring
Step 2 :
Unit rate refers to the value per hour.
Here, the cost for 1 hour of tutoring is $20.
∴ The unit rate is $20 per hour of tutoring.
The square root of 72 is rational because the answer can be a real number.
I believe question 3 is B and question 4 is B
This is all the picture showed omg toooo hard
Y=5x-3
the slope is plus 5
so if 1 = 2
simply subtract 5 from two and you get -3
