Log(base)4(3x-7)=log(base)4(x-15) could somebody me out with this question? i don't even know where to begin.

The bases of the logarithms on either side of the equation are the same, which means that their arguments must be the same:

Put another way, we can write both sides as powers of 4, then simplify and eliminate the logarithms:

Then solve for :

Then we just have to check if this solution is valid. On the left side, we have

but we can't take logarithms of negative numbers, so there is no solution, as long as we're using the real-valued logarithm, anyway; is a solution if we use the complex-valued version.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
