Again i’m confused.. show all work step by step so i understand?

solve for x: 6/x=4/8
a. 10
b. 12
c. 24
d. 48

Multiple across equal sign (Denominator x Nominator and vise versa)

6/x = 4/8

Cross multiply:

6*8 = 4 *x

48 = 4x

Divide both sides by 4:

x = 48 /4

x = 12

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
