Look at the temperature on this thermometor, If the temperature increases by 30 degrees, what is the new temperature?
A. -45
B. -15
C. 15
D. 45

c.15

Step-by-step explanation:

The temperature shown on the thermometer is -15 C

When you add 30 to -15 you get a sum of 15

what are the things "represented below"?

step-by-step explanation:

nobody can if you dont give the choices

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.
