Help I don’t know the answer

We can do this two ways. For now, we can just do it the easiest way.
Since they are giving us coordinates, let’s just plug them in and see if they work.
-3(2)+5(4)=2(2)+3(4)
-6+20=4+12
14=16
So, (2,4) is not an answer. Let’s test 3,3.
-3(3)+5(3)=2(3)+3(3)
-9+15=6+9
6=15
It’s neither.
Now, we can see the other way.
-3x+5y=2x+3y
Let’s move the y to one side and the x to the other. Let’s subtract 3y from both sides.
-3x+2y=2x
Now add 3x.
2y=5x
We could’ve plugged in the x and y values with this as well.
But the answer would be neither.

F - 3/4 = 5/6
Add 3/4 to both sides to get
F = 5/6 + 3/4 = 19/12

6) (after 2.3) Consider the infinite system of linear equations in two variables given by ax + by = 0 where (a, b) moves along t
Paraphin [41]

Answer:

Step-by-step explanation:

Given infinite system of linear equations is ax + by = 0

when (a,b) moves along unit circle in plane.

a) system having unique system (0, 0)

Since two of equation in thus system will be

1.x+0.y=0\\x=0

and

0.x+1.y=0\\y=0

It is clear that x = 0, y= 0 is the only solution

b) Linear independent solution in this system gives some set of solutions

1.x+0.y=0\\\x=0

and

0.x+1.y=0\\y=0

Vector form is

\left[\begin{array}{ccc}1&0\\0&1\end{array}\right] =I

c) for this equation if add 0x +0y = 0 to system , Nothing will change

Because [0,0] satisfies that equation

d) If one of the equation is ax + by = 0.00001

where 0.00001 is small positive number

so, the system will be inconsistent

Therefore, the system will have no solution.
