Mathematics
1 answer:
vampirchik [111]3 years ago
8 0

Answer:

Step-by-step explanation:

because The curve C crosses the x-axis at the origin and at the points A and B =>  the x coordinates of A and B are the solution of the equation:

 x(x + 4)(x - 2) = 0

<=> x = 0

      x = -4

      x = 2

because the x-coordinates of the points A and B aren't 0 and the x-coordinate

of A is a negative value

=>  the x-coordinate of  A is -4

the x-coordinate of B is 2

kondor19780726 [428]

Answer:t= 9

Step-by-step explanation: 10t =90

                                           divide 10 on both sides

                                            so 10t /10 and 90/10

                                             which means t=9

Answer:  D) Inverse does not exist

<u>Step-by-step explanation:</u>

The top row is 0 0 , which makes the determinant equal to zero.

The reciprocal of 0 is undefined so there cannot be an inverse for this matrix.
