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.

1. Is the product of √16 and 4/7 rational or irrational? Explain your reasoning.
Mandarinka [93]

1) Rational because the square root of 16 is 4 and 4 times 4/7 is a rational number (16/7)

2) Irrational because square root of 684 is irrational C

3) The square root of a is irrational so the answer is irrational. The square root of c is rational so the answer is rational.

4) Jacob is wrong because the square root of 5/7 is irrational so the answer to the problem is irrational.

Determine whether the ordered pair (1, 1) is a solution of the inequality. y ≤ -3x+1
solong [7]

-------------------------------------------------------------------------------------------------------------

Answer:  \textsf{(1, 1) is NOT a solution of the inequality}

-------------------------------------------------------------------------------------------------------------

Given:  y \le-3x + 1

Find:  \textsf{Determine if (1, 1) is a solution of the inequality}

Solution:  In order to determine if (1, 1) is a solution we need to plug in 1 for the x values and 1 for the y values and see if the equation evaluated to true.

<u>Plug in the values</u>

  • y \le-3x + 1
  • 1 \le-3(1) + 1

<u>Simplify</u>

  • 1 \le-3 + 1
  • 1 \le-2

As we can see the expression states that 1 is less than or equal to -2 which is false therefore (1, 1) is NOT a solution of the inequality.

DIA [1.3K]

Answer:

f(x) = y + (x*p)

Step-by-step explanation:

Since we are not given actual values we will need to make the function with only variables. Each variable will represent the following...

Fixed Cost: y

Cost per charm: p

Number of charms: x

Therefore, using the variables mentioned above we can combine them into the following linear function using the number of charms as our main input for our function...

f(x) = y + (x*p)
