Step-by-step explanation:
I cannot read the initial expression without doubt, but I just guess it is 3×sqrt(8).
that would make it : sqrt(9×8) = sqrt(72).
A is correct : sqrt(9)×sqrt(8) = sqrt(9×8) = sqrt(72).
B is correct : sqrt(6)×sqrt(12) = sqrt(6×12) = sqrt(72).
C is NOT correct : sqrt(6)×sqrt(24) = sqrt(6×24) = sqrt(144) = 12
D is correct : sqrt(3)×sqrt(24) = sqrt(3×24) = sqrt(72)
E is NOT correct : 72 is NOT sqrt(72)
F is NOT correct : sqrt(3)×sqrt(12) = sqrt(3×12) = sqrt(36) = 6
Answer:
y = 3x - 1
Step-by-step explanation:
Rise over run, so 3 over 1 = 3. The y-intercept is -1, so b = -1.
Answer:
The equation 'y = y + 1' represents NO SOLUTION.
Hence, option 'C' is true.
Step-by-step explanation:
a)
6a = 9a
subtract 9a from both sides
6a - 9a = 9a - 9a
-3a = 0
divide both sides by -3
-3a / -3 = 0/-3
Simplify
a = 0
b)
5x = 28
divide both sides by 5
5x/5 = 28/5
x = 28/5
c)
y = y + 1
subtract y from both sides
y - y = y+1-y
0 = 1
These sides are not equal, so
NO SOLUTION!
d)
y + 5 = 12
subtract 5 from both sides
y + 5 - 5 = 12 - 5
y = 7
Conclusion:
Therefore, the equation 'y = y + 1' represents NO SOLUTION.
Hence, option 'C' is true.
Answer:
3
Step-by-step explanation:
