Answer: it's 31.5
Step-by-step explanation:because you would times 9 by 21 then divide by 6
9*21=189
189/6=31.5
Changing the “m” or “b” would change the overall line on the graph. Meaning the line could be steeper or flatter. It could also change whether the line has a positive slope or negative. Likewise, when you use negative numbers for the m, the line will have a negative slope and will have a decreasing look to it. When you use negative numbers for the b, the y-intercept will be negative which will put the line further down the y-axis.
I hope this is what you were looking for! I kinda did it off the top of my head so of course feel free to change anything!!
Answer:
Step-by-step explanation:
<u>Given expression</u>:
To factor a quadratic in the form 
, first find two numbers that multiply to 
and sum to 
:
Two numbers that multiply to -36 and sum to 5 are: 9 and -4
Rewrite b as the sum of these two numbers:
Factorize the first two terms and the last two terms separately:
Factor out the common term (2x + 3):
Therefore:
