Y=x^2-5, solve for x
y+5=x^2
x=√(y+5) so
f^-1(x)=√(y+5)
The best equation would be A.
with A you get to calculate what is the value of $.
8 + $ = 10 (10 is the total value of your receipt and 8 is the price of pizza)
$ = 10 - 8 (we transfer the price of pizza on the other side to the total amount of your receipt and calculate the remaining amount)
$ = 2
We see that the remaining amount is 2$, which means the salad cost s2$ :)
1st add 7 to both sides : 3z = 21, 2nd divide both sides with 3: z = 7
Answer:
It is three times as large
Step-by-step explanation:
If a ration is also a fraction, and your wording is correct than an enlargement of 1:3 where 1 is the original shape would suggest that the 3 would be that same original shape, be enlarged in terms of 3 compares to 1 so a 300% enlargement.
if the original rectangle has a 16 cm perimeter, than the new rectangle has a 48 cm perimeter.
