Calculate (1/4)4
A. 1/4
B. 1
C. 1/256
d. 1/16

The answer is 1

Step-by-step explanation:

The answer is B. 1

Step-by-step explanation:

If you set up the equation in a different but also the same way like: 1/4 x 4/1, you can multiply just like that. First multiply the numerator which is 1 times 4 or also 4. Then you multiply 4 times 1 to get 4. Altogether you get 4/4 or if you simplify it, you get 1

A) 0.5(2) + 80 = 81

B) 83

C) f(4) = 0.5(4) + 80 = 82

g(x) = 2x + 79

Slope: (83-81)/(2-1) = 2

y = 2x + c

When x = 1, y = 81

81 = 2 + c

c = 79

g(x) = 2x + 79

g(4) = 2(4) + 79 = 87

Since 87 > 82,
