Ellen has a beginning balance of $370 in her checking account. she writes two checks for $40 and $50 respectively and deposits $210. what is her new balance?
$490
$70
$670
$20

5y

step-by-step explanation:

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.
