Answer:

Three non-collinear points determine a plane.

Step-by-step explanation:

This statement means that if you have three points not on one line, then only one specific plane can go through those points. The plane is determined by the three points because the points show you exactly where the plane is

Which graph shows the solution to the following system of inequalities x+y>4 x+y <3

LekaFEV [45]

Answer:

The following graph has no solution.

Step-by-step explanation:

Since , we are given a system of inequalities as:

x+y>4

and x+y<3

So from the two in equalities we could clearly see that in one the sum of x+y>4 while in the other the sun x+y<3 which is not possible.

This could also be seen from the graph.

The graph will not have any common region and are parallel lines.

Hence, the graph has no solution.

Factoring quadratics 4x^2-13x+3=0

ozzi

Answer:

X=3,1/4

Step-by-step explanation:

4x²-(12+1)x+3=0

or,4x²-12x-x+3=0

or,4x(x-3)-1(x-3)=0

or,(4x-1)(x-3)=0

Either,4x-1=0➡️ 4x=1

X=1/4

OR,x-3=0➡️ X=3
