Answer:
28
Step-by-step explanation:
Substitute 8 for x in g(x) = 5x - 12:
g(8) = 5(8) - 12 = 28
By using PEDMAS rule, g(8) = 28
PEDMAS rule states that the order of operation starts with the parentheses first or the calculation which is enclosed in brackets. Then the operation is performed on exponents(degree or square roots) and later we do operations on division & multiplication and at last addition and subtraction.
Given
g(x) = 5x - 12
Substitute x = 8
g(8) = [tex]5\times 8-12[/tex]
Calculate the product
g(8) = [tex]40-12[/tex]
Calculate the sum or difference
g(8) = 28
