Answer:
The unit price is the cost per unit of an item or the cost/price for each item.
1) <u>4$</u> per pound. By simplifying the proportion (constant ratio) between the cost, and the pounds of apples. 3 pounds of apples cost 12$ → 3/3 pounds of apples cost 12/3$ → 4 dollars for every pound.
2) <u>2$</u> per pound. By evaluating the rate of change (change in the y over x or dependent variable over independent) in the equation: y = <u>2</u>x. y is the cost in dollars, and x is the pounds of apples. So there are 2 pounds (weight) of apples for every dollar.
3) <u>3$</u> per pound. Given a graph with a y scaled by 3, and an x scaled by 1 with a graph y = x or 1 unit up for every unit right. This must be equivalent to y = 3x. Where y is labeled as the cost in dollars, and x as the weight in pounds. So there are 3 dollars for every pound of apples.
4) Store B. Because 2 is less than 3 which is less than 4.
Answer:
Well, everything can be turned into a half.
Step-by-step explanation:
The strategy that Lucy uses to recall her phone number is what is known as Chunking.
<h3>What is Memory?</h3>
This refers to the place where information is stored for future use and can either be a short or long-term memory.
Hence, we can see that based on the breaking down of her phone numbers of Lucy into a particular format that separates them using country/state code, she is making use of chunking.
This method of chunking is effective because it would help Lucy to recall her number quite easily.

The value of f(2) is -2 ⇒ 1st answer
Step-by-step explanation:
The form of the quadratic function is;
f(x) = ax² + bx + c, where
- a is the coefficient of x²
- b is the coefficient of x
- c is the numerical term
- x is the domain of the function and f(x) is the range of the function
∵ f(x) = -5x² - x + 20
- f(2) means value f(x) at x = 2
∵ x = 2
- Substitute x in the function by 2 to find f(2)
∵ f(2) = -5(2)² - (2) + 20
∴ f(2) = -5(4) - 2 + 20
∴ f(2) = -20 - 2 + 20
∴ f(2) = -2
The value of f(2) is -2
