Answer:
The given equation which is in two variable is
⇒2 x + y =9
As we know that to get a unique solution you need two intersecting lines.
But here only one line is given.
On a single line there lie infinite number of points.
So, for different values of x we get different values of y or different values of y we get different values of x.
So , we can write the above equation as
either ⇒y=9-2 x Or x=9-2 y
I have drawn graph for you.
Thus , there are infinite number of solution of this equation. Like (0,9),(1,7),(2,5),(-2,13),(-1,11),(-3,15)......
Answer:
Length = 90 inch.
width = 30 inch
Let width of the rectangle = x inch.
So the length = 3x inch.
Perimeter = 2(length + width) = 2 (3x + x) = 8x.
So,
length = 3x = 3(30) = 90 inch.
width = x = 30 inch

Step-by-step explanation:
Hi there!
Let's use x as our variable. We know that complementary angles add up to 90 degrees. So, angle 1 is equal to x. Then, we can figure out that angle 2 is equal to 2x - 15. Then, to solve for x, we need to set the value of angle 1 plug angle 2 equal to 90, since the angles are complementary.
WORK:
x + 2x - 15 = 90
3x - 15 = 90
3x = 105
x = 35
ANSWER:
x = 35
Hope this helps!! :)
