Answer:
   C'(-25, 5)
Step-by-step explanation:
The dilation scale factor is applied to each of the coordinate values independently:
   C' = 5×C = 5×(-5, 1)
   C' = (-25, 5)
 
        
             
        
        
        
Answer:
B
Step-by-step explanation:
From the given information:
Sienna has $8 denotes the unit blocks of x tiles. So, she saved $3 per week.
This implies that:
8x + 3(1) = 8x + 3
Also,
If Jacob as well had $6 which implies 6x unit block of tiles while he saved $4; 
i.e.
6(x) + 4(1) = 6x + 4
So;
the model that can determine when Sienna will have the same amount as Jacob is:
8x + 3 = 6x + 4
 
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
You have 3 unknowns: a, b, and c.  It's our job to find them algebraically.  I'm going to start with the point where x = 0 and y = 7.  You'll see why in a minute.  Filling in the standard form of a quadratic
 using (0, 7):
  using (0, 7):
 gives you that c = 7.  We will use that value now when we write the next 2 equations.  Now the point (-2, 19):
  gives you that c = 7.  We will use that value now when we write the next 2 equations.  Now the point (-2, 19):
 and
  and
 so
 so
12 = 4a - 2b
Now for the next point (-1, 12):
 and
  and
 so
  so
5 = a - b
Now we have a system of equations (the 2 bold font equations) that we will solve by elimination:
  12  =  4a  -  2b
   5  =   a   -    b
Multiply the bottom equation by -4 to get a new system:
  12  =  4a  -  2b
-20  = -4a  +  4b
Add those together to get rid of the a terms and end up with
-8 = 2b so
b = -4
Now we can sub in -4 for b to solve for a.  I'm using the second bold type equation to do this:
5 = a - (-4) and
5 = a + 4 so
a = 1 and the equation for the quadratic function is
