Step-by-step explanation:

It's D. 311 divided by 12 is 25.9
Answer:
50272
Step-by-step explanation:
Okay how I solve these equations is I take the problem apart like this:
3142 = 3000 + 100 + 40 + 2
Now we multiply each number by 16:
3000 * 16 = 48000
100 * 16 = 1600
40 * 16 = 640
2 * 16 = 32
Then we add all the totals together:
48000 + 1600 + 640 + 32 = 50272
Hope this Helps ;)
Answer:
They are both due to the wave nature of light.
For the X intercept you set y = 0 and solve for x
Y =

x + 9
0=

x + 9 subtract 9 from both sides
-9 =

divide both sides by 3
-3 = -8x divide both sides by -8

= x
X-intercept = (

, 0)
