Answer:
f(e - 9) = 8e - 67
Step-by-step explanation:
To evaluate f(e - 9) substitute x = e - 9 into f(x)
f(e - 9) = 8(e - 9) + 5 = 8e - 72 + 5 = 8e - 67
Answer:
15 cups of sugar
Step-by-step explanation:
Answer: (i) 4x - 40 = 76
(ii) 29 questions
Step-by-step explanation:
Let the total number of questions be x.
Since he received 4 points for every correct answer and he got 10 answers wrong , this means he lost 40 points , the equation thus become
4x - 40 = 76
To find the value of x , add 40 to both sides
4x = 116
divide through by 4
x = 29
Therefore , there are 29 questions on his math test
If it's nearest ten then it would be 5,760. If anything is 4 or lower than the number, like 74, then it would be 70.
If it was 5 or higher, like 37, then it would become 40.
Hope this helps! :)
