Answer:
Step-by-step explanation:
Let d= dramas
c= comedies
r= reality shows
Dramas are 1 hour long, comedies are 30 minutes, and reality shows are 2 hours long.
Total time spent on watching = 
[ 
]
Since he spent 8 hours for this, that means
→ First equation
He watches twice as many comedies as dramas.
i.e. 
→ second equation
So, the system of equations could be used to determine how many of each type of show he watches each week:
Answer:
Step-by-step explanation:
(13)2−(2x+7)=0
19x2−2x−7=0
9(19x2−2x−7)=9(0)
x2−18x−63=0
(x−21)(x+3)=0
Therefore, the value of x are
x - 21 = 0 and x + 3 = 0
x = 21 x = -3
Answer:
scale factor(k)=23
A(x,y)=A'(kx,ky)
Let's do by using this formula
C(9,0)=C'(kx,ky)(here x=9 and y=0)
C(9,0)=(23*9,23*0)
C(9,0)=(207,0)
A(0,3)=A'(kx,ky)(here x=0 and y=3)
A(0,3)=A'(23*0,23*3)
A(0,3)=A'(0,69)
Step-by-step explanation:
sorry i dont know how to do B no
Yes they're equal.
5 x 7/6
35/6
5 5/6
I hope i will be the brainiest<span> answer.</span>
The answer is D
They have the same slope but different yint.
