Jennifer started with $50 in her savings account. Each week she withdrew $10. The amount of money in her savings account after x weeks is represented by the function f(x) = 50 - 10x. Find the intercepts
Answers
The value of the intercepts are;
⇒ x = 5
⇒ y = 50
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The amount of money in her savings account after x weeks is represented by the function is,
⇒ f (x) = 50 - 10x
Now,
Find the intercepts as;
The function is,
⇒ f (x) = 50 - 10x
Put x = 0,
⇒ f (x) = 50 - 10 × 0
⇒ f (x) = 50
⇒ y = 50
And, Put y = 0;
⇒ f (x) = 50 - 10x
⇒ 0 = 50 - 10x
⇒ 10x = 50
⇒ x = 5
Thus, The value of the intercepts are;
⇒ x = 5
⇒ y = 50

50-10x=0
10x=50
x=5
x=0
y=50-0
y=50
Interceopt are x = 5 y = 50

Answer:
-3n-+21
Step-by-step explanation: 1. Get rid of the Parenthesis , so times -3 by what’s inside
2. If you multiply -3 by n you get -3n
3. if you multiply -3 by -7 you get 21 , you get a positive because a negative times a negative is a positive
4. so now you have -3n + 21 you don’t add these because -3n has a variable and 21 doesn’t have a variable , and if 21 did have a variable it would need to also be n
Answer:
−3n + 21
Step-by-step explanation:
This is the answer because:
1) You have to distribute everything from outside of the parenthesis to the inside
2) -3 times n is -3n
3) -3 times -7 is 21
4) Therefore, the answer is −3n + 21

Answers
Answer:
The average of the whole class is 80.8.
The correct answer is B)
Step-by-step explanation:
To solve this problem, it is very important to understand the phrase: "Ten students had an average of 88". Let's see an example.
Imagine that three students in the class took a test and their scores were: 80, 89 and 95. To calculate the average of they three we must divide the sum of the scores by the total number of scores.
The previous value is the average of the three students. Now, if we say that each student got 88, the average would be 88.
The previous expression could be simplified as:
Where, the number 3 means the number of students.
With that in mind, the phrase "Ten students had an average of 88" could be written as:
On the other hand, the phrase "The other students had an average of 76" means that from the 25 students, 15 students got 76 (25 - 10 = 15), and could be written as:
Finally, to calculate the total average of the 25 students we must divide the sum of the scores of all students by the total number of scores. The sum would be: 88+88+88+88+88+88+88+88+88+88+76+76+76+76+76+76+76+76+76+76+76+76+76+76+76, which equals . The total number of scores would be: 25.
Thus, the average of the whole class is 80.8. The correct answer is B)
The answer is B. 80.8
