Can you me with these problems? i mean tell me if i got them right or not..*sulk* - add and subtract integers-

-10 - 5 = -15?

-2 + 3 = 1?

4 - 7 = -3?

-8 + (-7) = -1?

answer and meh! ^^

answer: c

step-by-step explanation: because you don't have to draw a point of intersection. couldyou give me brainliest?

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.
