Which matrix represents the system of equation below? { 8x-9y+13z=11 -8x-5y+5z=15 3x+4y-8z=-10

In this question , we have the following equations

And we have to put these in matrix form.

We make a matrix for the numbers of the left side, a matrix for the variables x , y ,z , and a matrix for the numbers on the right side , that is

And that's the required matrix.

(-1,0) and (4,0) are x-intercepts.

step-by-step explanation:

x-intercepts are all points on the x-axis.

points (-1,0) and (4,0) are both x -intercepts.

answer: 12   they all have at least 28 days
