Answer:

2y - 9x - 40 = 0

Step-by-step explanation: i already done the test

100+(20×10)=300

30×10 =300

months = 10

The total cost becomes the same after 20 months of service, and the total cost is $600.

To find out when the total cost becomes the same for both companies, we need to compare their cumulative costs over time.

Tyson's Ethernet has an activation fee of $100 plus $20 per month, while Darriana's DSL costs $30 per month.

Let's set up equations for both companies:

For Tyson's Ethernet:

Total cost = Activation fee + Monthly charges

Total cost = $100 + ($20/month) * months

For Darriana's DSL:

Total cost = Monthly charges

Total cost = ($30/month) * months

We want to find when these two total costs are equal:

$100 + ($20/month) * months = ($30/month) * months

Now we can solve for the number of months:

$100 + ($20/month) * months = ($30/month) * months

$100 = ($30/month - $20/month) * months

$100 = $10/month * months

months = $100 / $10

months = 10

So, it takes 10 months for the costs to be equal. Now let's find the total cost at that point:

Total cost = ($30/month) * months

Total cost = ($30/month) * 20 months

Total cost = $600

Therefore, after 20 months of service, the total cost is the same for both companies, and the total cost is $600.

The Correct choice is D

For the function f(x) = -x+8, f(x-k) = f(x)+k.  Option (D) is correct.

Function is a combination of different types of variable and constants.

A function is denoted by f(x).

The given function is,

f(x) = -x+8,

Substitute x= x+k in the given function,

f(x+k) = -(x+k)+8

f(x+k) = -x-k+8

f(x+k) = -x+8-k

Substitute -x+8= f(x) here,

f(x+k) = f(x)-k

Substitute x= x-k in the given function,

f(x-k) = -(x-k)+8

f(x-k) = -x+k+8

f(x-k) = -x+8+k

Substitute -x+8= f(x) here,

f(x-k) = f(x)+k

Hence, option (D) is correct.

Answer:

  y = −3x −1

Step-by-step explanation:

The slope of the line between the two given points (-1, 2) and (1, -4) can be found using the slope formula:

  m = (y2 -y1)/(x2 -x1)

  m = (-4 -2)/(1 -(-1)) = -6/2 = -3

The slope is the coefficient of x in the slope-intercept equation for a line. Only one answer choice shows a slope of -3:

  y = -3x -1

_____

Additional comment

If you plot the given points and draw a line through them, you see that the y-intercept is -1. Or, you can use this equation to find the y-intercept from one of the points.

  b = y - mx

  b = 2 -(-3)(-1) = 2 -3 = -1

Now you know m=-3 and b=-1, so you can fill in the slope-intercept form equation:

  y = mx +b

  y = -3x -1

Answer:

 y = −3x −1

Perimeter = 4(2x - 1)

Step-by-step explanation:

Since the Perimeter of a square is 4L, it would be,

(2x - 1) + (2x - 1) + (2x - 1) + (2x - 1) which could also be shortened to 4(2x - 1)

Answer:

P = 4(2x - 1)

Step-by-step explanation:

Given that the side of each square is 2x - 1:

The formula for finding the perimeter of a square is:

P = 4s

where s represents the side of a square.

Substitute the given value for s into the perimeter formula:

s = 2x - 1

P = 4(2x - 1)

Therefore, the perimeter of the square is 4(2x - 1).

Answer:

piecewise, continuous.

Step-by-step explanation:

This is piecewise simply because it is in pieces. Thus PIECEwise (Pun intended). This is continuous because, as you can see, there is a filled in dot on the same x coordinate as every empty dot. The empty dots mean that that value is not in that part of the graph. However, since the other parts of the function "fill the gaps," then it is continuous.  I hope this helps!

It's offcourse piecewise

For continuity

Observe the graph

The domain is like

For close ineterval there is an open interval hence it's continuous

Answer:

Step-by-step explanation:

As, if we put the value (2,3) in the equation then,

2x + 10y = 20

=> 2(2) + 10(3) = 20

=> 4 + 30 = 20

=> 34 ≠ 20

Hence,

2x+10y=20 does not pass through (2,3)
