Let f(x) = x2 - 8x 5. Find f(-1).

Answers

Answer 1

Answer:

Answer:

f(-1)=14

Step-by-step explanation:

Given : Function - $f(x)=x^2-8x+5$

To find : The value of f(-1)

Solution : Follow the steps :

Step 1- Write the function

$f(x)=x^2-8x+5$

Step 2- Put x=-1 to find the value of f(-1)

$f(-1)=(-1)^2-8(-1)+5$

Step 3- Solve the above equation

$f(-1)=1+8+5$

$f(-1)=14$

Therefore, f(-1)=14

Answer 2

Answer: in the equation you have to replace all x's with -1

f (-1) = (-1)^2 - 8(-1) +5
f (-1) = 1 + 8 + 5
f (-1) = 14

the f(-1) stand for the function of -1. it is also equivalent to y

The Wilsons have triplets and another child who is fifteen years old. The sum of the ages of their children is 36. How old are the triplets?

Answers

the answer is 37-10=27/3=9

Answer:

Step-by-step explanation:

The Wilsons have triplets and another child who is 15. Since their ages all add up to 36, we can first start off with subtracting 15 from 36.

36 - 15 = 21

Now we can divide the amount we have from the rest amount of kids, since they are triplets, they are 3:

21 / 3 =
