Answer:
x=3 or x=−9
Step-by-step explanation:
Step 1: Subtract 27 from both sides.
x2+6x−27=27−27
x2+6x−27=0
Step 2: Factor left side of equation.
(x−3)(x+9)=0
Step 3: Set factors equal to 0.
x−3=0 or x+9=0
x=3 or x=−9
Answer:
x=3 or x=−9
They only have 1 common point
I am pretty confident its 1.0
Answer: A. c = 3d
I'm gonna go with c = 3d
Step-by-step explanation: c = 3d
After looking at the table I believe the equation would be c=3d. I came to this conclusion because (6)=3(2); (9)=3(3); (15)=3(5); 18=3(6). I really hope this helps!:)

Answer:
Step-by-step explanation:
Days Cost
2 6
3 9
5 15
6 18
Now to find equation that models the given data we will use two point slope form.
Formula:
Substitute the values in the formula
where y denotes the number of days and x denotes the cost
Let us suppose d denotes the number of days and c denotes the cost
So, equation becomes:
Hence an equation models the data in the table is
So, option A is true.
