Answer: cost of 1 pot of ivy = $12
Cost of 1 rose bush =$ 10
Step-by-step explanation:
Step 1
Let rose bushes be represented as r
and pot of ivy be represented as p
such that Amy who spent 82 dollars on 7 rose bushes and 1 pot of ivy can be expressed as
7 r + p = 82----- eqn 1
Rob who spent 74 on 5 rose bushes and 2 pots of ivy can be expressed as
5r +2 p = 74----- eqn 2
Step 2
Solving
7 r + p = 82----- eqn 1
5r +2 p = 74----- eqn 2
By elimination method Multiply eqn 1 by 5 and eqn 2 by 7
35r+ 5p= 410--- eqn 3
35r+ 14p =518--- eqn 4
Subtracting eqn 4 from eqn 3
9p = 108
p = 108/9
p=12
p = pot of ivy = $12
therefore rose bush wll be ( from equation 1)
7r+ p= 82
7r=82-12
7r= 70 r= 70/7
r= rose bush =$ 10

Answer:
Step-by-step explanation:
Given:
The function,
A standard parabola with vertex at origin is represented as:
The above function is a standard parabola with vertex at origin and opening upward.
The vertex of the above function is at the origin 
and the value of 
is 1.
Now, the function is translated 4 units up.
So, from the rule of function transformations, if a graph is moved up by 
units, then units is added to the function.
Therefore,
.
Also, the vertex of 
will be translated 4 units up. So, the co-ordinates of the vertex of 
will be 
Now, express the above function in the vertex form 
.
We have 
This gives,
