Answer:
A. t(x) = 450 - 0.06x
Step-by-step explanation:
The layer which is originally 450 m thick is decreasing by 0.06 m.
450 - 0.06
... per day. x represents days.
0.06x
So,
450 - 0.06x
Answer:
1.35 is rounded to 1 because the .3 is not a .5 if it was 1.55 it would be 2

Answer:
-25, -14, -10, -9, -8, -7, 0, 2
Step-by-step explanation:
You do thing and it work
I think the easiest way to answer all of these is to just go ahead and find the equation of the line first.
I'm pretty sure that by the time you reach this problem, you've learned to find
the equation of a line that passes through two given points. You have two points: (2, 100) and (5, 205). The equation of the line through them is [ y = 35x + 30 ].
6). The initial membership fee ... the cost for walking in the door and signing up,
before any months, is $30. (Also the y-intercept.)
7). The cost per month is $35. (The slope of the line.)
8). We already did that, up above. [ y = 35x + 30 ].
9). 'x' in the equation is the number of months.
There are 12 months in one year.
y = 35(12) + 30 = $450
Given the fact that AB≈AD, then 35 is also the angle measure of ADB. The sum of the angles of a triangle =180. 35+35=70. 180-70=110
X=110°
