Answer:
Step-by-step explanation:
- 8x+ 8 = 0
we divide the coefficient of the X by half :
in this case: 8x/2 = 4 , then we do the following
to the result obtained (4) squared: 4^2=16
we sum and subtract by 16 to maintain the balance of equation:
- 8x+ 16-16+8 = 0
we have:
-16 +8=0
=16-8
= 8
we write the square root on both sides of the equation:
we know:
so we have:
abs(x-4)=
abs(x-4)=2
we have:
finally we have:
Answer:
Has one to one correspondence
Answer:
1. 4
2. No solution in real numbers, in complex it is 11i and -11i
3. 4
4. 17
5. 8
Step-by-step explanation:
1. f = sqrt(16) = 4
2. No real solution
3. h^2 = 16, h = 4
4. k-4 = 13, k = 17
5. 2m-1=15, m = 8
Answer:
157 degrees
Step-by-step explanation:
the two angles should add up to 180 degrees, so 180 - 23 = 157
