Which of the following systems of linear equations has one solution? {x = 3 y =5}
{y = 3x + 3 y = 3x}
{ x = 3 x =5}
none of the above

50-60=10

step-by-step explanation:

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)

i think the answer is d im not sure

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
