Solve the equation for y.<br> 3x + 7y= 29

Oxana [17]

Answer:

y = $\frac{29-3x}{7}$

Step-by-step explanation:

3x + 7y = 29 ( subtract 3x from both sides )

7y = 29 - 3x ( divide both sides by 7 )

y = $\frac{29-3x}{7}$

Write the sum using summation notation, assuming the suggested pattern continues. 1 - 3 + 9 - 27 + ...

meriva

There is no sum for this geometric series. it diverges rather than converges due to the absolute value of the common ratio (r), which is -3, being 3. for a geometric series to have a sum (to converge), the absolute value of r must be less than 1.
(you find r by dividing a2/a1, a3/a2, etc.)
hope this helps
