A TV remote control has keys for channels 0 through 9.
a) If a key is selected at random, what is the probability that the key for channel 8 is pressed?
b) If a key is selected at random, what is the probability that the key for an even number is pressed?
c) If a key is selected at random, what is the probability that the key for a number more than 6 is pressed?

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.

it is x=-4

step-by-step explanation:

income. 10x+1300

expenses 3x+(1800+1500)

expenses 3x+3300

to break even:

income = expense,

10x + 1300 = 3x + 3300,

solve for x.
