Answer:

y=−4

Step-by-step explanation:

Let's solve your equation step-by-step.

7y−4=−32

Step 1: Add 4 to both sides.

7y−4+4 =−32+4

7y =−28

Step 2: Divide both sides by 7.

7y/7 = −28/7

y=−4

(/:divide) Hope it helps!!

Leon usually does very well on tests, but he failed his most recent math exam. His teacher was very upset by Leon's performance
kondor19780726 [428]

Answer:

situational

Step-by-step explanation:

Based on the information provided within the question it seems that Leon's teacher made a situational attribution about his test performance. This term refers to when certain people believe that an individual's actions or behaviors are caused by a specific or various situational factors. Which is what his teacher is thinking by believing that his performance was affected by some problem or sickness (situational factors).

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
