Answer:
David used 1/2 of apple juice for every 1/4 cup of cranberry juice to make a fruit drink
one gift was $6.40 and the other was $19.20
Step-by-step explanation:
the answer is 10-6x (B)
f(x)=-4x+/4
let y=f(x)
y=-4x+4
interchange the role of x & y
x=-4y+4
x-4=-4y
(x-4)/-4=y
y=-(x-4)/4
f-¹(x)=-(x-4)/4
yeah you are right
i hope i have been useful buddy.
good luck ♥️♥️♥️♥️♥️.
