Ellie, the elephant eats 4 times as much as popcorn the pony, zac the zebra eats twice as much as popcorn altogether they eat 238 kilograms of food per week how much foos does each of them require per week

Answer=Elephant:34kg  Pony:136kg  Zebra:68kg

elephant:pony:zebra
1:4:2
1+4+2=7
238/7=34
1*34=34kilograms (elephant)
4*34=136kilograms (pony)
2*34=68kilograms (zebra)

Elephant=34kg
Pony=136kg
Zebra=68kg

Replace f(x)f(x) with yy.y=x2−1y=x2-1

Interchange the variables.x=y2−1x=y2-1

Solve for yy.
y=√1+x,−√1+xy=1+x,-1+x

Solve for yy and replace with f−1(x)f-1(x).
This is your answer=f−1(x)=√1+x,−√1+xf-1(x)=1+x,-1+x
Hope you have a wonderful day! hope this helps!
