Answer:
8/2 or 4 is the slope i hope this helps :)
Step-by-step explanation:
y = 4x - 6
y = 8/2x - 6
For 12. Neil's mistake was that he didn't combine like terms of both the constant and numbers with both the variable of k. 9 and -8 are both constants so you combine it and get an answer of 1 since 9+ -8 is 1. 12k and k both have the variable of k so you combine it and get 13k.
The simplified version should be: 13k+1=12k-1
For 13. The third expression would be equivalent to the expression above listed as 12r+6s. The third expression is 4(3r+s)+2s and if you do PEMDAS you will get the same answer. Parentheses, 4 times 3r is 12r and 4 times s is 4s and after that you get 12r+4s+2s. As said before, if they have like terms you combine it so you get 12r+6s and it will equal the same as the one shown above.
Hope this helped you and would love brainiest! <span />
52+x would just remain like that because you cannot combine them
Answer:
Step-by-step explanation:
Simplify the expression:
Grouping like terms, 10x² + 5x² + 4 x - 4 x - 1 + 3 = (10 x² + 5x²) + (4 x - 4 x) + (-1 + 3):
10x² + 5x² = 15x²:
3 - 1 = 2:
4 x - 4 x = 0:
