For number one. Go to may then up to 55. Crawl before you walk. Just plot the points on the graph and make sure the line goes through 0,0
To solve the above inequality we will try to isolate j by using the opposite operation of a number that we want to remove. So,

Add 8 to each sides.
By combining the like terms.
Multiply each sides by 4 to isolate j.
j<48 By simplifying.
So, the answer is j<48.
Mhm 86(7)+88=839 that’s ur answer
The answer to your question is option d as x is positive ( making it open up), and the vertex is (-3,-4)
