Answers
Answer:
f ( x ) = ( x - 5 ) ² - 20
Step-by-step explanation:
1- Add the same value to both sides
f ( x ) = x ² - 10x + 5
2- Add 25 to the expression
f ( x ) + ? = x ² - 10x + ? + 5
3- Add 25 to the left-hand side
f ( x ) + ? = x ² - 10x + 25 + 5
4- Factor the expression
f ( x ) + 25 = x ² - 10x + 25 + 5
5- Move the constant to the right
f ( x ) + 25 = ( x - 5 ) ² + 5
6- Calculate
f ( x ) = ( x - 5) ² + 5 - 25

= a² - ab + ab - b² = a² - b²

Answers
Answer:
1.15
Step-by-step explanation:
Answer:
1.15
Step-by-step explanation:
So, first it would be helpful to change this from an improper fraction to a mixed number. Because we have an improper fraction now, we need to make this a mixed number by seeing how many times 23 can go into 20. Twenty-three can't go into 20, but if we take away 3 from 23 it can.
So, now we have 20/20 but with a remainder of 3/20. Because 20/20 = 1, it becomes a whole number of 1 and 3/20. Because there is a whole number of 1, we can put this as the whole number for the decimal. The fraction 3/20 is equal to the decimal 0.15, so we can now put the decimal together now that we have all the parts for the answer needed, which is 1.15.
I hope that this helps.

Multiply by x on (2):
x^2 + xy = -22x
x^2 + 40 = -22x
x^2 + 22x + 40 = 0

Answers
Answer:
1) y > x
2) x > 5 > y
3) x ≤ 4 ( or 4 ≥ x )
4) x = y
Step-by-step explanation:
1) 1. y is greater than x
2. so y > x
2) 1. 5 is less than x and more than y
2. we can write this like x > 5 > y
3. you can just squish them together as a shortcut usually: x > 5 and 5 > y --> x > 5 > y
3) 1. x is for at most, we can say this as x is less than or equal to 4
2. this is written as x ≤ 4 or 4 ≥ x
4) 1. x - y = 0 so x and y must be the same value
2. therefore x = y
