C for the first and d for the last one
Answer: A.
Step-by-step explanation:
According to the recipe,
For 2 batches, 3 cups of flour required.
One batch has 15 mix rolls
Then 2 batches will have 2 (15) = 30 rolls
Each person gets one roll, so 3 cups of flour is required for 30 people.
The quanity of flour is proportional to the number of people.
Let x be the quantity of flour required for 12 people.
By proportion,
Required proportion:
The correct option is A.
180 - 79
101 degrees is the answer
C.
Let g(x) = y. This gives you y =
Manipulating the above equation gives you x = 8y^3 + 6 which is f(y), meaning that f(g(x)) = x so f and g are inverses of each other.
4x+2(3-2x)=10, 4x+6-4x=10, x+6=10, x=4
