Answer:

Given the equation

C = 20n + 35

We need:

n ≥ 15 and C ≤ 600

following

20n + 35 ≤ 600
20n ≤ 565
n ≤ 565/20
n ≤ 28 (rounded to the whole number)

Considering that n ≥ 15, we have:

15 ≤ n ≤ 28

And the cost is going to be:

20*15 + 35 ≤ C ≤ 20*28 + 35
335 ≤ C ≤ 595

(2,8),(7,8) slope of the line

aliina [53]

Answer:

The slope of line is 0 given points (2,8)(7,8)

Step-by-step explanation:

We need to find slope of line given points (2,8),(7,8)

The formula used to find slope of line is: $Slope=\frac{y_2-y_1}{x_2-x_1}$

We are given:

$x_1=2, y_1=8, x_2=7 \ and \ y_2=8$

Finding slope using formula:

$Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{8-8}{7-2}\\Slope=\frac{0}{5}\\Slope=0$

So, the slope of line is 0

goldenfox [79]

Answer:

Following are the solution to the given points:

Step-by-step explanation:

In point 1:

The Reflexive closure:

Relationship R reflexive closure becomes achieved with both the addition(a,a) to R Therefore, (a,a) is $(0,0),(1,1),(2,2) \ and \ (3,3)$

Thus, the reflexive closure: $R={(0,0),(0,1),(1,1),(1,2),(2,0),(2,2),(3,0), (3,3)}$

In point 2:

The Symmetric closure:

R relation symmetrically closes by adding(b,a) to R for each (a,b) of R Therefore, here (b,a) is: $(0,1),(0,2)\ and \ (0,3)$

Thus, the Symmetrical closure:

$R={(0,1),(0,2),(0,3)(1,0),(1,1)(1,2),(2,0),(2,2),(3,0), (3,3)}$
