{put the given value of j and k in the given equation.. and solve }

0.45

Step-by-step explanation:

This question is asking you to find the value of the equation when j = -4 and when k = -0.7. To do this, we must substitute j with -4 and k with -0.7:

(-4 * -0.7 - 1) / -4

= (2.8 - 1) / 4

= (1.8) / 4

= 0.45
