Janelle has taken 4 tests so far and has an 87 average. she is taking two mor tests, each od which will be scored out of 100, qith no extra credit. if she wants her final test average to be 90, what is the lowest she can score on one of the tests?

She will have to score at the very least a 92 on one of the tests to have the possibility of 90%

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
