According to Vieta's Formulas, if
are solutions of a given quadratic equation:
Then:
is the completely factored form of
.
If choose
, then:
So, according to Vieta's formula, we can get:
But
:
![d^4-8d^2+16=(d^2-4)^2=[(d+2)(d-2)]^2=(d+2)^2(d-2)^2](https://tex.z-dn.net/?f=d%5E4-8d%5E2%2B16%3D%28d%5E2-4%29%5E2%3D%5B%28d%2B2%29%28d-2%29%5D%5E2%3D%28d%2B2%29%5E2%28d-2%29%5E2)
<span>perpendicular slope :
m1 * m2 = -1
1/2 * m2 = -1
m2 = -2
y = -2x + b
2 = -4 +b
b = 6
y = -2x + 6

Answer:
isn't there a problem to this ?
Step-by-step explanation:
Answer: Therefore, Option 'A' is correct.
Step-By-Step explanation:
Since we have given that
Amount spent on equipment = $36
Amount spent on fees = $158
Amount spent on transportation = $59
Total amount spent by them is given by
Percent cost of equipment of the total amount is given by
Percent cost of fees of the total amount is given by
Percent cost of transportation of the total amount is given by
Hence, Percent cost of the total spent on each is
14%, 62%, 23%.
Therefore, Option 'A' is correct.
Answer:
x=90
Step-by-step explanation:
So, since x-20 is the vertical angle directly near 70, we can say:
x-20=70.
if we solve x is 90.
