Answers: A , B , and D are correct.
________________________________________________________
The following statements are true and correct:
____________________________________________________
[A]: y is a function of x .
____________________________________________________
[B]: The graph of the relationship is a line.
____________________________________________________
[D]: When the input is -2, the output is 3.
____________________________________________________

Note:
____________________________________________________
Choice: [C]: "When the input is -3, the output is 4 ." → is INCORRECT.

Note: When the input is -3, the output is "4 <span>⅓";
that is, when x = -3, y = 4 </span>⅓ .
_____________________________________________________
Choice: [E]: "The y-intercept of the relationship is: (0,1)." → is incorrect.

Note: The y-intercept refers to the value of "y" where the line crosses the "x" axis. From the equation; and form the graph, we see that the y-intercept is: "⅓" ; or, "(0, ⅓)" .
<span>________________________________________________________
</span>Here is the graph of the equation:
____________________________________________
y = $- \frac{4}{3} x + \frac{1}{3}$ ;

Would do anything for the answer to this question

<u>Given</u>:

The length of the entire rectangle is 10x + 7.

The width of the entire rectangle is 6x.

The length of the unshaded rectangle is 4x - 5.

The width of the unshaded rectangle is 2x.

We need to determine the area of the shaded region of the rectangle.

<u>Area of the entire rectangle:</u>

The area of the entire rectangle can be determined using the formula,

$A=length \times width$

Substituting the values, we have;

$A_1=(10x+7)(6x)$

$A_1=60x^2+42x$

Thus, the area of the entire rectangle is 60x² + 42x

<u>Area of the unshaded rectangle:</u>

The area of the unshaded rectangle can be determined using the formula,

$A=length \times width$

Substituting the values, we have;

$A_2=(4x-5)(2x)$

$A_2=8x^2-10x$

Thus, the area of the unshaded rectangle is 8x² - 10x

<u>Area of the shaded region of the rectangle:</u>

The area of the shaded region of the rectangle can be determined by subtracting the area of the entire rectangle by the area of the unshaded rectangle.

Thus, we have;

$A=A_1-A_2$
