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:
67.
Step-by-step explanation:
n - m = 66
The 66 includes the number m+1 up to and including n (buy not m).
So the number of integers is 66 +1 = 67
???????????? I don’t get it?
<span>What is the y-intercept of the plane whose equation is 4x + 5y + z = 20?
(0, 4, 0)
Which equation has intercepts at X(1, 0, 0), Y(0, 1, 0), and Z(0, 0, 2)?
2x + 2y + z = 2
Which equation is equivalent to x + 3y + z = 3?
4x + 12y + 4z = 12
Which of the following points lies in the plane 3x + 2y + 4z = 12?
(4, 3,2)
Hope these answer the questions. Have a nice day.</span>
Answer:
24/5 (4.8)
Step-by-step explanation:
5:8 = 3:x
Divide both sides by 3
5:24 = 1:x
That means 24/5 = x
