The slope of the line is (1/2).
The original equation is y=mx+b
m = slope
x = variable 
b = y-intercept
        
             
        
        
        
Answer:
The statement is false.
Step-by-step explanation:
A parallelogram is a figure of four sides, such that opposite sides are parallel
A rectangle is a four-sided figure such that all internal angles are 90°
Here, the statement is:
"A rectangle is sometimes a parallelogram but a parallelogram is always a
rectangle."
Here if we found a parallelogram that is not a rectangle, then that is enough to prove that the statement is false.
The counterexample is a rhombus, which is a parallelogram that has two internal angles smaller than 90° and two internal angles larger than 90°, then this parallelogram is not a rectangle, then the statement is false.
The correct statement would be:
"A parallelogram is sometimes a rectangle, but a rectangle is always a parallelogram"

Answer:
) See annex
b) See annex
x  =  0,5 ft
y =  2 ft   and
V = 2 ft³
Step-by-step explanation:  See annex
c) V = y*y*x
d-1) y = 3 - 2x
d-2) V = (3-2x)* ( 3-2x)* x   ⇒ V = (3-2x)²*x    
V(x) =( 9 + 4x² - 12x )*x    ⇒   V(x) = 9x + 4x³ - 12x²
Taking derivatives
V¨(x) = 9 + 12x² - 24x
V¨(x) = 0              ⇒   12x² -24x +9 = 0     ⇒  4x² - 8x + 3 = 0
Solving for x (second degree equation)
x =[ -b ± √b²- 4ac ] / 2a
we get    x₁  =  1,5       and    x₂ =  0,5
We look at y = 3 - 2x    and see that the value x₂ is the only valid root
then
x  =  0,5 ft
y =    2 ft   and
V = 0,5*2*2
V = 2 ft³
