You can show that it equals 5.5y by distributing

4.50y+1y=y(4.50+1)=y(5.5)=5.5y

answer is 5.5y

It would be 5.5y because y equals 1.

-4=r/20-5

First add 5 to both sides
1=r/20

Then multiply both sides by 20
20=r

Final answer: r=20

7.
(v+9)/3=8

First multiply both sides by 3
v+9= 24

Subtract 9 from both sides
v=15

Final answer: v=15

Write the expression as a single logarithm 7log(x) y + 6 log(b) x

daser333 [38]

Answer: $log(x)^{7y}+log(b)^{6x}=log(x^{7y}b^{6x}).$

Step-by-step explanation:

Given logarithm expression

$7log(x)^y + 6 log(b)^x.$

We need to write it as a single logarithm expression.

First we need to apply exponent rule of logs to remove 7 and 6 in front of logs.

$n log(p) = log(p)^n$

$7log(x)^y + 6 log(b)^x.= log(x)^{7y}+log(b)^{6x}$ .

Now, we need to apply product rule of logs $log(p)+log(q) = log(pq)$ .

$log(x)^{7y}+log(b)^{6x}=log(x^{7y}b^{6x}).$

Therefore, final answer is $log(x)^{7y}+log(b)^{6x}=log(x^{7y}b^{6x}).$
