Answer:
a=(c+2b)/5
Step-by-step explanation:
Like terms in one side to subject a.
When exchanging sides make sure u do inverse operations. Therefore;
9a - 4a = c + 2b
5a = c + 2b
a = (c+2b)/5
Answer:
These points are hard to graph, so I have a website that you can go to instead and all you have to do is put in the points and then once you're done type in correlation coefficient and then type in (A,B,C, D, E, etc.) and you'll be given the correlation coefficient. I put a picture with my attempt at graphing. I hope this helps, sorry I couldn't graph it for you

Answer:
a = -12
Step-by-step explanation:
3a – 5(a - 2) = 34
→ Expand out the brackets – 5(a - 2)
– 5(a - 2) = – 5(a + 2) = -5a + 10
→ Substitute that back into the equation
3a - 5a + 10 = 34
→ Simplify the 'a's
-2a + 10 = 34
→ Minus 10 from both sides to isolate -2a
-2a = 24
→ Divide both sides by -2 to isolate a
a = -12
