The better buy is "16 oz. for $2.49". This can be found by dividing $2.69 by 12 and getting about $0.22 (amount per ounce) and dividing $2.49 by 16 and getting about $0.16 (amount per ounce).

Assume the parent function has been shifted up

mars1129 [50]

Answer:

If $y=(x-2)^2+4$ is the transformed function, then the parent function $y=x^2$ has been shifted up vertically by 4 units and horizontally right by 2 units

Step-by-step explanation:

Assume the function is $y=f(x)$ is the parent function.

A vertical shift,b units up will transform the function to $y=f(x)+b$ .

A horizontal shift $a$ units.

$y=f(x-a)+b$

For instance, if $y=x^2$ , b=4, and a=2 units.

Then the transformed function becomes:

$y=(x-2)^2+4$

Adrian has $6.35 in dimes and quarters. The number of dimes is three more than three times the number of quarters. How many quar

Mrrafil [7]

I: 635=dimes*10+quarters*25
or shorter
635=d*10+q*25

II: d=q*3+3

Substitute II (d=3q+3) into I to replace d:
635=d*10+q*25
635=(3q+3)*10+q*25
635=30+30q+25q
605=55q
11=q

-> 11 quarters

"What expression represents the number of dimes if q represent quarters"
insert q=11 into II:
II: d=q*3+3
d=11*3+3
d=33+3
d=36
