Question 8 options:
prisoha [69]

Answer:

Step-by-step explanation:

Based on what you have here as the slope we can set the slope formula equal to 34 using the points (0, 8) and (8, c) to solve for c, then use the points (0, 8) and (a, 5) to solve for a.  

c first:

\frac{c-8}{8-0}=34 and

\frac{c-8}{8}=34 and

c - 8 = 272 s0

c = 280

For a:

\frac{5-8}{a-0}=34 and

\frac{-3}{a}=34 and

-34a = 3 so

a=-\frac{3}{34}

That seems a little weird, but when you plug those points into the slope formula to solve for the slope, it works out the way it should.

A bag contains green marbles and blue marbles, 18 in total. The number of green
Katena32 [7]

Answer:

Step-by-step explanation:

Let the number of blue marbles be x

The number of green marbles = 3x - 2

Total marbles= 18

x + 3x -2 = 18

4x - 2 = 18

     4x = 18+2

      4x = 20

x =20/4

x =5

The number of blue marbles = 5

The number of green marbles = 3*5 - 2 = 15 -2 = 13

How to find the rule of this sequence: 11, 18,25,37?
Arturiano [62]

Hey there! Thanks for asking your question here on Brainly!

You can find the rule to this sequence fairly easily. Take the last number (37) and subtract the second-to-last number (25) from it. That gives you 12. Next, take 25 and subtract 18 from it, which equals 7. Lastly, take 18 and subtract 11 from it, which equals 7. Therefore, the sequence is arithmetic.

The rule would be +7, +7, +12

Finding the rule involves taking one number and subtracting the number before it in order to find the difference between the two numbers, or how the sequence changes.

Hope this helps!! If there's anything else I can help you with, please let me know! :)
