Find the area of the shaded region
Simora [160]
Answer: D. The area is 50 square meters if the shaded area looks like .

Explanation:
assuming this is a rectangle, the larger region area is 15*5= 75 square meters.
The smaller region’s area would be 10*5= 50 square meters.
• remember that A=lw, where l is length and w is width.


Without an illustration & on the assumption this is a rectangular region, here are the conclusions:
• given these two areas,
If the shaded area looks like , the area is just 50 square meters because the dimensions needed to solve for the area were given.
OR
• If the shaded region looks like subtract the smaller area from the larger one: 75-50= 25 square meters. (However, given that this is not an answer choice, I don’t think the illustration would look like this).

A student used the equation below to create a table. y = –3x – 5 The student used –2 as one of the values for the input. Which o
Angelina_Jolie [31]

The ordered pair that could be taken from the table is: C. (–2, 1).

<h3>Ordered pairs of a Table</h3>

Ordered pairs are given as, (x, y). To find either x or y of a pair given an equation, plug in the given given to find the corresponding missing value of the ordered pair.

Input value = x-values, while output value = y-values.

Given:

y = –3x – 5

Let's find the corresponding y-value (output) of x = -2.

Substitute x = -2 into y = –3x – 5.

y = –3(-2) – 5

y = 6 - 5

y = 1

Therefore, the ordered pair that could be taken from the table is: C. (–2, 1).
