Answer:
39 ft²
Step-by-step explanation:
Area of a triangle = 1/2bh
Let:
base = b = 4 ft
height = h = 3 ft
Solve for the area of the triangle:
A = 1/2(4)(3)
A = 2 * 3
A = 6 ft²
Area of a rectangle = bh
Let:
base = b = 9 ft
height = h = 5 ft
Solve for the area of the rectangle:
A = (9)(5)
A = 9 * 5
A = 45 ft²
Subtract the area of the triangle from the area of the rectangle:
45 - 6 = 39 ft²
39 ft² is your answer.

V(j + y) = 61y + 82
Vj + Vy = 61y + 82
Vy - 61y = 82 - Vj
y(V - 61) = 82 - Vj
y = (82 - Vj)/(V - 61)

Pretty sure this is the answer haha.
Answer:
<h2>y = -2x + 1</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:

<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
The formula of a slope:

We have two points (1, -1) and (2, -3).
Substitute:

Put it and the coordinates of the point (1, -1) to the equation of a line:

<em>add 2 to both sides</em>

Finally:
