Since y is the suqraed term, it opens left or right
in this form it is
(y-k)²=4p(x-h)
(h,k) is the vertex
if p is negative then it opens to the left and directix is to the right of the vertex
if p is positve then it opens to the right and directix is to the left of the vertex
p is the distance from vertex to directix
so
(y-0)²=4(-6)(x-0)
the vertex is (0,0)
-6 is negative
so
vertex is (0,0)
directix is 6 unts to the right of (0,0) or at x=6
the directix is x=6
Alita received 24 dollars and 25 cents ($24.25) as change at the grocery store.
For given question,
Alita received twenty-two dollars, seven quarters, and five dimes as change at the grocery store.
The value of coins is all counted in cents.
1 Penny = 1 cent
1 Nickel = 5 cents
1 Dime = 10 cents
1 Quarter = 25 cents
And 1 Dollar = 100 cents
Alita received seven quarters, and five dimes coins as change at the grocery store.
seven quarters = (7 × 25) cents
= 175 cents
five dimes = (5 × 10) cents
= 50 cents
The total coins are:
seven quarters, and five dimes
= 175 + 50 cents
= 225 cents
Now we add all change together.
twenty-two dollars, seven quarters, and five dimes
= 22 dollars + 225 cents
= 22 dollars + 2.25 dollars
= 24.25 dollars
= $24.25
Therefore, Alita received 24 dollars and 25 cents ($24.25) as change at the grocery store.

Answer:
The annual difference in the cost between the two cars in gasoline plus monthly payment per month will be $856.67.
Step-by-step explanation:
Car option "A" gets 18 miles per gallon of gas (MPG) and has a monthly payment of $368.
Now, yearly 12000 miles will consume gallons of gas.
Now, if the gas costs $2.89 par gallons, then yearly fuel cost is $(666.67 × 2.89) = $1926.67
Hence, the yearly cost for option A will be $(1926.67 + 368 × 12) = $6342.67.
Now, car option "B" is a hybrid and gets 60 MPG with a monthly payment of $409.
Now, yearly 12000 miles will consume gallons of gas.
Now, if the gas costs $2.89 par gallons, then yearly fuel cost is $(200 × 2.89) = $578
Hence, the yearly cost for option B will be $(578 + 409 × 12) = $5486.
So, the annual difference in the cost between the two cars in gasoline plus a monthly payment per month will be $(6342.67 - 5486) = $856.67. (Answer)
Step-by-step explanation:
let y = x+5/4
Interchanging x and y , we get ;
x = y+5/4
or, 4x = y+5
or, 4x-5 = y
or, g(x) -1 = 4x-5
