If you write
, you'll notice this is really just a quadratic equation that can be factorized:
So you have
and
Answer:
i believe the answer is A and D
Answer:
Step-by-step explanation:
It is given that AC:CM = 3:4.
Therefore, let AC = 3k and CM = 4k
It is given that Δ ACM is right angled.
Therefore,
AM = 5k
But, AM = MP + AP
Therefore, MP + AP = 5k --- (1)
It is given that MP - AP = 1 --- (2)
Multiply (1) and (2), we get.
(MP + AP)(MP - AP) = 5k × 1 = 5k
Add and subtract on the left side.
--- (3)
But, since CP ⊥ AM, Δ CMP and Δ CAP are right triangles. Therefore,
and
Now, (3) becomes,
7k = 5 or
AM = 5k
Answer:
D.) This system has infinitely many solutions
Step-by-step explanation:
y = -4x - 6
-4x - y - 6 = 0
-4x - y - 6 = 0
-y = 4x + 6
-y/-1 = 4x/-1 + 6/-1
y = -4x - 6
There are infinitely many solutions, because both of the lines are exactly the same. As show below ! Hope this helps once again ^w^
