Answer:
Step-by-step explanation:
12x - 3y = 10
-3y = -12x + 10
y = 4x - 10/3....the slope here is 4
parallel lines will have the same slope
y = mx + b
slope(m) = 4
(-5,3)...x = -5 and y = 3
now we sub and find b, the y int
3 = 4(-5) + b
3 = -20 + b
3 + 20 = b
23 = b
so ur equation is : y = 4x + 23 <==
the a = 30
200,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,001

6x0.5=3-12=9
=================================================
Work Shown:
x^2 - 5x + 1 = 0
x^2 + 1 - 5x = 0
x^2 + 1 = 5x
(x^2 + 1)/x = 5 .... where x is nonzero
(x^2)/x + (1/x) = 5
x + (1/x) = 5

An alternative method involves solving the original equation using the quadratic formula. After you get the two roots x = p and x = q, you should be able to find that p + 1/p = 5 and also q + 1/q = 5 as well.
In this case,
p = (5 + sqrt(21))/2
q = (5 - sqrt(21))/2
BC=20
AE= 18
<ABC= 114 degrees, <DAB=66 degrees
To find DAB you subtract 180 from 114
