Answer:
B. y ≤ 1/2x + 3
Step-by-step explanation:
To write the equation of the inequality, use the linear equation form y = mx + b. The y-intercept is b and is where the line intersects the y-axis. Here b = 3. You can find the slope m by counting between points the vertical and horizontal distances. Here it is 1/2. Substitute m = 1/2 and b = 3.
y = 1/2x + 3
Since this is an inequality and a solid line has been used, you must use ≤ and ≥. To determine which is for this equation, test the point (0,0) in each.
y ≤ 1/2x + 3 y ≥ 1/2x + 3
0 ≤ 1/2(0) + 3 0 ≥ 1/2(0) + 3
0 ≤ 3 True 0 ≥ 3 False
Since (0,0) is a part of the set of solutions, the equation which is true is the correct equation.
The two operations are multiplication and subtraction.
The constants are 2 and 6.
The expression is written as 2(n – 6).
Explanation: "twice the difference" meaning two times an expression. The two operations here are multiplication and subtraction because there is a parenthesis and there is a "-" sign within the parenthesis. 2 and 6 are constant numbers.
1. Find the unit rate
15 books divided by 5 days = 3 books sold per day.
Since we are looking for how many days it would take the store to sell 21 bucks, we could do 21 (amount of books) divided by 3 (how much books is sold in a day).
Therefore, it will take a week / 7 days to sell 21 books.
