We conclude that:
Step-by-step explanation:
Given
h(a) = a² - 5
g(a) = -4x
To determine
(hog)(2)
Using the formula
(hog)(2) = h(g(2))
First determining the g(2)
substitute x = 2 in g(a) = -4x
g(a) = -4x
g(2) = -4(2) = -8
so
(hog)(2) = h(g(2)) = h(-8)
now determining the h(-8)
substitute x = -8 in h(a) = a² - 5
h(a) = a² - 5
h(-8) = (-8)² - 5
h(-8) = 64 - 5
h(-8) = 59
so
(hog)(2) = h(g(2)) = h(-8) = 59
Therefore, we conclude that:

Answer:
Colt
Step-by-step explanation:
Solve for x in both cases. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and equals:
Parenthesis
Exponents (& roots)
Multiplication
Division
Addition
Subtraction.
Jose:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Add 3.5 to both sides:
5x - 3.5 = 12.5
5x - 3.5 (+3.5) = 12.5 (+3.5)
5x = 16
Next, divide 5 from both sides:
(5x)/5 = (16)/5
x = 16/5
x = 3.2
Colt:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 3 from both sides:
(x/5) + 3 (-3) = 12 (-3)
x/5 = 12 - 3
x/5 = 9
Next, multiply 5 to both sides:
(x/5)(5) = (9)(5)
x = 9 * 5
x = 45
Colt has the larger solution.
