1 answer:

6 0

I think the correct answer from the choices listed above is the second option. Solving a 6 order system <span>would be the process that is used to describe solving a system of equation with 6 variables. The number of variables should be equal to the order of the system for it to be solved. Hope this answers the question.</span>

If the gradient of a line is 2 and (7,2) is a point on the line, find it's equation

choli [55]

Answer:

y = 2x - 12

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 2 , then

y = 2x + c is the partial equation

To find c substitute (7, 2 ) into the partial equation

2 = 14 + c ⇒ c = 2 - 14 = - 12

y = 2x - 12 ← equation of line

Answer:

9x² - 9y + 9

Step-by-step explanation:

Step 1: Write out expression

3 - 2y - 1 + 5x² - 7y + 7 + 4x²

Step 2: Combine like terms (x²)

9x² + 3 - 2y - 1 - 7y + 7

Step 3: Combine like terms (y)

9x² - 9y + 3 - 1 + 7

Step 4: Combine like terms (constants)

9x² - 9y + 9

Mr. Walker is looking at the fundraiser totals for the last five years.

MrRissso [65]

1. If you want to find the mean you should add all fundraiser totals and divide it by number of years:

$\text{ the mean }=\dfrac{896+925+880+963+914}{5} =915.6.$

2. In order to find the median, firstly you have to order the fundraiser totals from the smallest number to the greatest number:

880, 896, 914, 925, 963.

The median is the middle number, then

$\text{ the median }=914.$

3. 915.6-914=1.6 - the mean is $1.60 greater than the median.

Answer: correct choice is B.
