If the points a(2, 1, 1), b(0 ,-1 ,4)& c(k ,3 ,-2) are colinear, then k=
a)0
b)1
c)4
d)-4

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

well we know there are 4 clubs in 52 cards so it’s replaced so it should be 3/51

step-by-step explanation:

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
