Answer:
The width of rectangle w = 4 units
Step-by-step explanation:
We are given:
Width of rectangle = w
Length of rectangle = w+ 4
Area of rectangle = 32 units
We need to find width of the rectangle
The formula used is: 
Putting values and finding width of rectangle

We need to solve this quadratic equation to find width (w)
We will use factorisation and break the middle term.

Since width of rectangle can't be negative, so rejecting w=-8
Therefore, the width of rectangle w = 4 units
Answer:
n = 16
Step-by-step explanation:
8n/9 = 6.4/0.45
Cross multiply.
0.45 * 8n = 9 * 6.4
3.6n = 57.6
n = 16
Y = -4x + 2
3x + 2y = 6 (or in y-intercept form y=-3/2x + 3)
2x - y = 7 equals y = 2x -7 in y-intercept form. This means that the line has a positive slope and therefore goes upwards. This cannot be a potential equation because the line shown is clearly pointing downwards.
y=5 indicates that the line is a horizontal line that neither points upwards or downwards. This cannot be a potential equation because the line is pointing downwards.
The only possible equations left are y= -4x + 2 and 3x + 2y = 6, both of which graph a line pointing downwards because their slopes are negative. Hope this helps!
Answer:
Domain is the values of x within the function and y is the values of y within the function. They are the defined values for x, and y respectively, where the function results in a function. For any function, the domain is the input value and the range is the output values.
Hope this helps :)
Option D would be the correct answer.
