Scale of the model = 3.5 / 10.5 = 1/3
so the length of the model = 1/3 * 12 = 5 feet
Area of the scale model = 4 * 3.5 = 14 sq ft

The point (3, 2) is the solution to given system of equations
<em><u>Solution:</u></em>
Given that system of equations are:
------ eqn 1
------- eqn 2
From eqn 2,
y = 2x - 4
Substitute y = 2x - 4 in eqn 1

Let us solve the above equation by quadratic formula,

Using the Quadratic Formula for
where a = 5, b = -16, and c = 3

The discriminant
so, there are two real roots.

Substitute for x = 0.2 and x = 3 in 2x - y = 4
<em><u>when x = 3</u></em>
2(3) - y = 4
6 - y = 4
y = 2
<em><u>when x = 0.2</u></em>
2(0.2) - y = 4
0.4 - y = 4
y = 0.4 - 4
y = -3.6
Thus Option D is correct The point is (3, 2)
