Let y = x^2 - 1
x^2 = y + 1
x = sqrt(y + 1)
so f^-1(x) = sqrt (x + 1) (answer)
Answer:
9 should be added to both sides of the equation to complete the square.
Step-by-step explanation:
Given : 
To Find: What number should be added to both sides of the equation to complete the square?
Solution:
Add the square of half of coefficient of x
So, the square of half of coefficient of x = 
So, 
Thus 9 should be added to both sides of the equation to complete the square.
Answer: All but one was right
1. 0 (correct)
2. 34 (correct)
3. 398 (correct)
4. -350 (correct)
5. 20 (correct)
6. 200 (wrong)
7. 48 (correct)
8. -1000(correct)
9. 150 (correct)
10. -55 (correct)
Step-by-step explanation:
(2x5)x(9÷3)+4=10x3+4=30+4=34
4(25x8÷2)+3-5=4(200÷2)+3-5=4x100+3-5=400+3-5=403-5=398
-10x20-30(5)=-200-150=-350
5x10-30=50-30=20
4(50-20÷4)+20=4(50-5)+20=4x45+20=180+20=200
3x4(20÷5)=12x4=48
-20(50x2)+5(200)=-20x100+5x200= -2000+1000=-1000
20x5+70-20=100+70-20=170-20=150
-5+10x(-5)==5+-50=-55
