Answer:
A (0,0)
Step-by-step explanation:
When a function intersects the y-axis then the point of intersection is called y-intercept of the function,
Also, for y-intercept x = 0.
That is, if f(x) is the function then its y-intercept is (0, f(0) )
By the given table for x = 0, f(x) = 0
Hence, the y-intercept of the given function is (0,0),
Option A is correct.
The answer for the first one is 48 fluid ounces
Answer:
Teacher's age is 32.
Step-by-step explanation:
How you count the average age for people is:
(age of person 1 + age of person 2 ... ) / number of people = average age
Let's start by observing that we've got 2 equations coming from the text:
- average of just students
20 students x 11 (average for a student) = sum of age of students
20 x 11 = 220 - average of student and teacher
let's say x is age of teacher
together students & teacher is 20 + 1 = 21 people
(20 students x 11 + x)/ (20 + 1) = 12
(220 + x) / 21 = 12
220 + x = 12 * 21
x = 12 *21 - 220
x = 252 - 220
x = 32
hope this helps ❣️
I think the answer is C if it’s not Then it’s A
True, it is the converse
x = 17 + 4 = 21
