All you need to do is round up 17 and 38 to 20 and 40 in your head. Solve for that in your head and then subtract 5 from the sum.

20+40=60
60-5+55

what is the inverse of h(x)=12e^2x. based on your answer write an expression write an expression equivalent to where x is h of 1
dezoksy [38]
Let y = 12 e^2x

e^2x = y/12
Taking [email protected]
ln e^2x = ln (y/12)

2x = ln (y/12)

x = (1/2) ln (y / 12)

so the inverse h-1(x)  = (1/2) ln ( x / 12)

Pls help ;-;
anyanavicka [17]

Answer:

C

Step-by-step explanation:

A closed circle means inclusive, and -2 is included in values that would make the equation true. Then you just have to test another number greater than and less than -2 to see which way the arrow should point.

-3(-3) + 1 < 7

9 + 1 < 7

10 < 7 FALSE

-3(0) + 1 < 7

1 < 7 TRUE

All values (including -2) will make this equation true
