Answer:
C. 31
Step-by-step explanation:
The recursive definition tells us the 4th term is 22 and the common difference is -3. This lets us write an explicit formula for the n-th term:
f(n) = f(4) +d(n -4)
f(n) = 22 -3(n -4) = 34 -3n
Substituting n=1 into this formula, we get ...
f(1) = 34 -3(1) = 31
The first term is f(1) = 31.
Answer:
x=-6
y=-6
The slope is the line that goes on forever, the line isn't in any other area then the cordinites above.
Answer:
USE CALCUKATOR LAAAAHHH!!!
6y = -x - 7
<span>y= 6x - 3 </span>
<span>__________________ </span>
<span>y = x/6 + 7/6 </span>
<span>y= 6x - 3 </span>
<span>Compare the gradients, one is 1/6, one is 6. These are not parallel because they aren't the same, and not perpendicular because they aren't negative reciprocals. Therefore, neither.</span>
So hmmm recall the "inscribed angle theorem", notice the first picture
thus, check the second picture, recall, a flat line line AOD is 180° wide
