Notice that if you just plug in
into the equation for
, you end up with
You have to do the same thing with the given choices. For example, if
then we see that
, and plugging this into the second equation gives
which matches the original set of parametric equations.
So the general strategy is to eliminate the parameter
by solving for it in each
equation. Then substitute this result for the
in the corresponding
equation, and see if it reduces to the same equation at the top.
1 7/12 becuase 2 neg is a neg, 1 neg and 1 pos is which is bigger in this case it is pos.
Answer: 517
Step-by-step explanation:
9514 1404 393
Answer:
Step-by-step explanation:
The midpoint formula is useful here. For midpoint M, we have ...
M = (C + D)/2
2M = C + D
2(10, 10) = (15, s) +(t, 3)
(20, 20) = (15+t, s+3)
t = 20 -15 = 5
s = 20 -3 = 17
__
<em>Check</em>
(C +D)/2 = ((15, 17) +(5, 3))/2 = (20, 20)/2 = (10, 10) . . . checks OK
Answer:
2p^2 - 1p - 8 GCF= 2p
Step-by-step explanation:
The GCF of the following equation can be written as 2p.
So with this information, we can solve the equation.
2p^2 - 1p - 8
Let me know if I am correct.
