Answer:

Step-by-step explanation:
Let the width of the rectangle be 'w' inches
length of the rectangle= (2w+9) inches
Perimeter of the rectangle= 48 inches
Perimeter of a rectangle= 2(Length+Width)




<span>30 square units.
The area of a parallelogram is
A= bh
where
A = area
b = base
h = height
Any side of a parallelogram can be used as the base. The height of a parallelogram is a perpendicular line from the base to the opposite side of the parallelogram. If needed, you can replace the opposite line segment with a line that overlays the line segment and continues to infinity in both directions.
Given the 4 points, the line segments (4,1) to (10,1) and (8,-4) to (2,-4) are the most interesting. Both of those lines have a slope of 0, which makes finding the distance between those two lines trivial. The height is simply the difference in their y-coordinate values. So
h = 1 - (-4) = 1 + 4 = 5
And the length of the base is the difference between their x-coordinates. (You can use either line for the base). So
b = 10 - 4 = 6
So the area is
A = bh
A = 6 * 5
A = 30</span>
Answer:
yes, the given relation is a function.
Step-by-step explanation:
The given relation is
{(–3, –2), (–1, 0), (1, 0), (5, –2)}
A relation is called function if each element of the domain is paired with exactly one element of the range.
It means for each value of x there exist a unique value of y.
In the given relation for each value of x there exist a unique value of y.
Therefore the required solution is yes and this relation is a function.
Answer:
x = 3, and y = 2
Step-by-step explanation:
2x + 3y = 12 -------- (1)
y = x - 1 ---------------(2)
Substitute value of Y in (2) in (1)
2x + 3(x-1) = 12
2x + 3x - 3 = 12
5x - 3 = 12
5x = 12 + 3
5x = 15
x = 15/5
x = 3
Put the value of x in equation 2
y = x-1
y = 3 - 1
y = 2
Therefore, x = 3, and y = 2
