6 0

Answer:

Not a solution

Step-by-step explanation:

y ≥ 2x + 5

=> Substituting x = 2 and y = -1 in Equation,

=> -1 ≥ 2(2) + 5

=> -1 ≥ 4 + 5

=> -1 ≥ 9     [Not possible]

Therefore, (2,-1) is not a solution of y ≥ 2x + 5

exponential equation:

nb=a

logarithmic equation: logna=b

log 8 = log 2^x = xlog 2

log 2^3 = 3log 2 = xlog 2

x = 3
