Answer: A function is a relation in which each input has only one output. In the relation , y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y. x is not a function of y, because the input y = 3 has multiple outputs: x = 1 and x = 2.
Step-by-step explanation:
Answer:
Step-by-step explanation:
→ State the gradient formula
( y₂ - y₁ ) ÷ ( x₂ - x₁ )
→ Find x₁ , x₂ , y₁ and y₂
x₁ = 4 , x₂ = 12 , y₁ = 9 and y₂ = 20
→ Substitute in the values
→ Simplify
Answer: Yes, and she will have 4 cups leftover
Step-by-step explanation:
1 Quart = 4 cups
Convert the quarts: 7 * 4 = 28
Find the amount of cups needed in total: 12* 2 = 24
Subtract to see if possible: 28- 24 = 4
