4. which shows a system of equations that can be entered into a graphing calculator to solve
16.9-2.3 = 3.2x + 18?
a y = 16.9x and y = 3.2x
b y = 16.9x - 2.3 and y = 3.2x + 18
c 0 = 16.9x - 2.3 and 0 = 3.2x + 18
d y = 13.7x - 20.3

is there any attachment? what are the equations?

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680
