Answer:
D) 0
There is 1 real solution.
Step-by-step explanation:
Hi there!
This is written in standard form:
This means:
a=9
b=30
c=25
The discriminant states:
If D>0, there are 2 real solutions.
If D=0, there is 1 real solution.
If D<0, there are 2 complex solutions.
Plug in the values:
Therefore, there is 1 real solution.
I hope this helps!

Answer:
parallel : y = -4x + 4
perpendicular : y = 1/4x + 4
Step-by-step explanation:
y= 4-4x is
y = -4x + 4 (rewritten)
parallel line will have the same slope
so
y = -4x + 4
perpendicular is a negative reciprocal
so
-4x become 1/4x
so
y = 1/4x + 4
X-5 + 5x-12 = 25
combine like terms
6x-17 = 25
add 17
25 + 17 =42
6x + 42
x = 7
