<span>6x + 10y = 32 (mult. eq by 2)
6x + 2y = 22
subtract:
8y = 10
y = 1 0/8 = 1.25
x = 16 - 5y = 9.75
cost/lb of walnuts = $1.25
cost/lb of chocolate chips = $9.75</span>
1/27
Cuz y=3^(-3)=1/(3^3)=1/27
The 2-point form of the equation of a line is
.. y = (y2 -y1)/(x2 -x1)*(x -x1) +y1
For your points (x1, y1) = (0, 3) and (x2, y2) = (3, 5), this is
.. y = (5 -3)/(3 -0)*(x -0) +3
.. y = (2/3)x +3
Written as a function, it is
.. f(x) = (2/3)x +3
Answer:
If you are asking for the type of quadrilateral, then it could be a rectangle or a square.
