Which equation represents the approximate line of best fit for data, where x represents font size and y represents the number of
wlad13 [49]
The table containing the data needed for this problem is attached on this answer. This data is used to determine the best fit line that is extracted from this multitude of points given. Best fit line is described as a line in which the variation of each point to the line is the minimum. We plot the data using MS Excel and is shown in the figure attached as well. We determine the trendline of the graph by the function in MS Excel. The equation of the trendline is expressed as <span>y = -26.059x + 722.63 in which the coefficient of determination, r^2 = 0.8947. </span>

Find the solution:<br> 3x + 2y = 12<br> -2x + 3y = 5
finlep [7]

Answer:

x = 3

y = 2

Step-by-step explanation:

3x + 2y = 12

-2x + 3y = 5 to find the solution we will use elimination method and for that, multiply second equation with 3 and the first equation with 2

<em>2 * 3x + 2y = 12</em>

<em>6x + 4y = 24</em>

<u>3 * -2x + 3y = 5</u>

<u>-6x + 9y = 15</u>  now find the sum of both equation:

<em>6x + 4y  </em><u>-6x + 9y</u> = 24 + 15 add like terms

13y = 39 divide both sides by 13

y = 3 now that we found the value of y we can use this to calculate the value of x

3x + 2y = 12 replace y with 3

3x + 2*2 = 12

3x + 4 = 12 subtract 4 from both sides

3x = 9 divide both sides by 3

x = 3

Josh sold his bike for 10% less than he paid for it. IF he sold the bike for 585 how much did he pay for it?
tangare [24]

Answer:

To know how much he bought it for, let's consider the actual amount it be x.

Step-by-step explanation:

10% of x + $585 = x

x/10 + $585 = x

$585 = x-x/10

$585= 9x/10

9x=$5850

x=$5850/9

x=$650

.: the actual price was $650.
