Help fill in the blanks plz
Nady [450]

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

Which answer is the best estimate of the correlation coefficient for the variables in the scatter plot.
Sholpan [36]

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

The site is: geogebra and it is a graphing calendar: https://www.geogebra.org/graphing

6. Solve for a: 3a – 5(a - 2) = 34<br>1. a = 1<br>2. a = -12<br>3. a = -22<br>4. a = 0​
Sauron [17]

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
