Answer:
A. the increase in the number of pounds a boy gains each year
Step-by-step explanation:
Any function that can be written as:
y = ax + b
is called a linear function.
Slope of the function (or sometimes referred to as "steepness") is determined by the value of a, which is 1.73 in our case. Since y is number of boy's pounds and x is his year, that means that for every year (when x changes by 1), the boy's weight (y) will change by 1.73.
Value of a is positive (1.73), which means that for each year, from this 5 to 18 interval, boy's weight will increase.
The surface area of a rectangular prism can be found by adding the area of all sides together. To start, we will have to find the dimensions for the new prism, which is 5 * 6 * 8.
Then, we will have to find the area for each side. One of the sides will have 8*6, another 8*5, and the last 5*6.
We will then have 48, 40, and 30. Multiply them all by 2 and add them all together.
You will receive the final answer of 236 square inches.
86.40/12.8=6.75. 45.60/9.5=4.8 so yellow fabric costs more
