A classmate claims that ⎡⎣160013⎤⎦ is the inverse of [6−183] . Explain her misunderstanding of matrices.

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions.a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0

The graph shows the distance kerri drives on a trip. what is kerri's speed?

Using only odd number for numerators write two different subtraction problems that have a difference of 3/4
