so you have

sqrt(3)/2 ^2 = 3/4 = 0.75

14 kg of apples cost $154.how much would 16kg cost
ankoles [38]
We can set up a proportion, and let x be the amount 16kg would cost: 14/154=16/x. We simplify 14/154 = 1/11. Next, we cross-multiply to get (1)(x)=(16)(11), so x=176. Therefore, 16kg of apples cost $176.

Graph the ordered-pair solutions of y=lx-1 when x=-5, -3,,0,1,2.
34kurt
Y = x - 1
y = -5 - 1
y = -6
(x, y) = (-5, -6)

y = x - 1
y = -3 - 1
y = -4
(x, y) = (-3, -4)

y = x - 1
y = 0 - 1
y = -1
(x, y) = (0, -1)

y = x - 1
y = 1 - 1
y = 0
(x, y) = (1, 0)

y = x - 1
y = 2 - 1
y = 1
(x, y) = (2, 1)
