You can take the log of the left and right hand side, and then apply the <span>logarithm rules: log(a</span>ˣ) = x·log(a) log(ab) = log(a) + log(b) log(9^(x-1) * 2^(2x+2)) = log(6^(3x)) log(9^(x-1)) + log(2^(2x+2)) = 3x log(6) (x-1) log(9) + (2x+2) log(2) - 3x log(6) = 0 x(log9 + 2log2 - 3log6) = log9 - 2log2 x = (log9 - 2log2) / (log9 + 2log2 - 3log6) simplifying by writing log9 = 2log3 and log6 = log2+log3 x= 2(log3 - log2) / (2log3 + 2log2 - 3log2 - 3log3) = x= -2(log3 - log2) / (log3 + log2) = -2 log(3/2) / log(6) So 6^x = 4/9

Answer:
56cm, y=5x+6
Step-by-step explanation:
The baby panda's initial or starting length is 5cm. This is the y-intercept or b value. We also know that the panda increases every week by 5 cm. This is the rate of change or slope. This is m. We can write in slope-intercept form y=mx+b.
y=5x+6
We substitute x=10. y=5(10)+6=56cm
