What is the question? If you are only trying to expand the expression then the answer would be:

1/4 (5y-3)+ 1/16 (12y+17)

(5y/4) – (3/4) + (12y/16) + (17/16)

1.25y – 0.75 + 0.75y + 1.0625

2y + 0.3125

If you are trying to find for y, then you forgot to equate it to 0, that is:

2y + 0.3125 = 0

2y = -0.3125

Answer:

y = 1

Step-by-step explanation:

$\frac{y + 3}{16} = \frac{2}{8} \\ = > y + 3 = \frac{2 \times 16}{8} \\ = > y + 3 = 2 \times 2 \\ = > y + 3 = 4 \\ = > y = 4 - 3 \\ = > y = 1$

Show that solving the equation 3^2x=4 by taking common logarithms of both sides is equivalent to solving it by taking logarithms

Sophie [7]

Answer:

Step-by-step explanation:

Case I: use common logs:

2x log 3 = log 4, or 2x(0.47712) = 0.60206

Solving for x, we get 0.95424x = 0.60206, and then x = 0.60206/0.95424.

x is then x = 0.631

Case II: use logs to the base 3:

2x (log to the base 3 of 3) = (log to the base 3 of 4)

This simplifies to 2x(1) = 2x = (log 4)/log 3 = 1.262. Finally, we divide this

result by 2, obtaining x = 0.631
