"You stupid"
"No Im not"
"Whats 9+10"
"21"
The unit rate is 2 cups of flour per cup of sugar.
Given y = f(x)
Substitute x = 10.
Therefore f(x) = 13 when x = 10
inequality
x = 2 ; y = -1
y = 1/2*x - 2 and y = -3*x + 5
1/2*x - 2 = -3*x + 5
7/2*x - 2 = 5
7/2*x = 7
x = 2
y = 1/2*2 - 2 = -1
y = -3*2 + 5 = -1
