I think c. Hope this helps
Answer:
The correct answer is D. (1,6)
Step-by-step explanation:
When plugged into the equations, it is written 10(1) + 2(6) = 22 and 3(1) - 4(6) = -21. For the first one, 10 x 1 = 10 and 2 x 6 = 12. 10 + 12 = 22. For the second one, 3 x 1 = 3 and 4 x 6 = 24. 3 - 24 = -21. This makes both equations correct, making (1,6) the answer.
The domain is the charity amount and range is the donation.
<h3>How to find the domain and range?</h3>
The collection of all x values, or independent quantity, for which the function f(x) exists or is defined, is known as the domain. Range is the collection of all y values, the dependent quantity, that are produced when all x values (the domain) are substituted into the function. All x and y values that could be used to solve the inequality are referred to as the domain and range, respectively. A solution is any set of values that could be used to prove the inequality.
Given: The amount to be donated is 250 dollars and half of the charity amount.
Let x= donation amount and y= charity amount
This can be written as x= f(y) where x= 250+y/2
Thus since domain is an independent variable therefore charity is the domain and range being the dependent variable, donation would be considered as range.

Answer:
The answer is C
Step-by-step explanation:
It is nonlinear but you have to look at it compared to the months passed. In three months the total houses built are 33 this would mean each month they build 11 houses but in the fourth month they have built 46 houses because 46-11 dosnt equal 33 it is nonlinear.
The difference between the perimeters of the two rectangles will be 4x + 3
The formula for the perimeter of rectangle is given as :
P = 2(L + B)
Where P = perimeter of the rectangle
L = length of the rectangle
B = breadth of the rectangle
Now we have given two rectangle on is smaller than the other.
To find the difference between the perimeter of the two rectangles. We will first calculate the perimeter of both the rectangle.
Perimeter of the bigger rectangle = 2( 5x + 3 + 2x)
= 2(7x + 3)
= 14x + 3
Perimeter of the smaller rectangle = 2(2x + 3x)
= 2*5x
=10x
Difference between the two perimeters = (Perimeter of the bigger rectangle) – (Perimeter of the smaller rectangle)
= (14x + 3) – 10x
= 4x + 3
Thus the difference between the perimeters of the two rectangle will be 4x + 3
