4.50 /2 = 2.25
11.25/5 = 2.25
22.50/10 = 2.25
the constant is the price per pound which is 2.25
(adding the second equation to the first one)
8 / 6.403 = 1.249...
nearest tenth = 1.2
The function with the domain {2, 3, 4} is the function y = 3x + 2, making the answer equal to A.
y = 3x + 2 y = 3(2) + 2y = 6 + 2y = 8
y = 3x + 2y = 3(3) + 2y = 9 + 2y = 11
y = 3x + 2y = 3(4) + 2y = 12 + 2y = 14
I notice that the range of the function y = 3x + 2 is {8, 11, 14}, making the answer equal to D.
The correct answer is (-4)(3)+(-4)(1/4)
