Y=-3x + 4 y= 3x-2 How do you graph this on a line

1 answer:

8 0

Plug in values for x and then you will get a value for y
Example: if you plug in 1 for x than you’d get an answer for y so you’d have a pair of points (1,y) then you plot those points on the graph. Or you could use Desmos graphing calculator online and plus the equations into the website to graph it for you.

Make up a data set of five values with a mean of 10 and a median of 12 None of the values in your data set can be reapeted

Tanya [424]

Answer: See explanation

Step-by-step explanation:

Let the numbers be 2, 6, 12, 13 and 17.

From the given numbers, the mean will be:

= (2+6+12+13+17) / 5

= 50/5

= 10

The mean is 10

The median is 12 as it is the number in the middle when the values given are arranged in either ascending or descending order.

S is located at (9 -3) point T is located at (4 -3)

cupoosta [38]

Answer:

Step-by-step explanation:

The distance formula is:

$d = \sqrt {\left( {x_2 - x_1} \right)^2 + \left( {y_2 - y_1} \right)^2 }$

We can plug in the given coordinates into the equation:

$d = \sqrt {\left( {4 - 9} \right)^2 + \left( {-3 - (-3)} \right)^2 }\\d = \sqrt {\left( {-5} \right)^2 + \left( {-3+3} \right)^2 }\\d = \sqrt{25 + \left( {0} \right)^2 }\\d=\sqrt{25+0}\\d=\sqrt{25}\\d=5$

An online retail company determined that their cost for each day, x, can be determined by the function C(x) = 2x2 – 20x + 80 and

sammy [17]

The number of days the company earns a profit is the second day till the 7th day

<h3>How to determine the number of days the company earns a profit?</h3>

From the question, we have the following functions that can be used in our computation:

Cost function, C(x) = 2x2 – 20x + 80

Revenue function, R(x) = –x2 + 5x + 58

These functions can be properly represented as

Cost function, C(x) = 2x² – 20x + 80

Revenue function, R(x) = –x² + 5x + 58

When the company makes a profit, the revenue of the company exceeds the cost

This means that

R(x) > C(x)

Substitute the known values in the above equation, so, we have the following representation

–x² + 5x + 58 > 2x² – 20x + 80

Evaluate the like terms

–3x² + 25x - 22 > 0

Expand

–3x² + 3x + 22x - 22 > 0

Factorize the inequality

–3x(x - 1) + 22(x - 1) > 0

So, we have

(-3x + 22)(x - 1) > 0

This gives

-3x + 22 > 0 and x - 1 > 0

Evaluate

-3x > -22 and x > 1

Divide

x < 7.3 and x > 1

This can be combined as

1 < x ≤ 7

Hence, the company makes profit from the second day till the 7th day

Your free ride to work ends in 14 days. So, maybe you need a car? How much can you afford to spend? Below is what's available at

garri49 [273]

Step-by-step explanation:

Kindly find attached a screenshot of the price list of some cars from motor 1 .com since you did not provide any in the question, and let us assume it is the same as what is available at a dealership near you.

From the list, since you don't have enough money in your account to buy a car, I will say you should get a 2017 Nissan Versa for $11,990

and 25% of $11,990 is

(25/100)* 11,990

0.25* 11,990

$2997.5

So you can make a down payment of $2997.5

and pay the remainder of $8992.5 later
