Answer:

Shorter piece is 3 ft, longer piece is 8 ft

Step-by-step explanation:

Set up two equations...

Let x be the length of the shorter piece, and let y be the length of the longer piece.

The whole board is 11 feet long, so

x + y = 11

He wants the longer piece to be 4 feet less than 4 times the length of the shorter board, so

y = 4x - 4

Substitute the second equation into the first equation....

x + 4x - 4 = 11           (y becomes 4x - 4)

Now solve for x

5x = 15                 (combine like terms, add 4 to both sides)

   x = 3                (divide both sides by 5)

Now substitute 3 in for x in either equation and solve for y...

y = 4(3) - 4

    y = 12 - 4

            y  =  8

100 BRAINLY POINTS!!!
BARSIC [14]

Answer:

C)   y=-0.5x+8

Step-by-step explanation:

Line of best fit (trendline) : a line through a scatter plot of data points that best expresses the relationship between those points.

All the given options for the line of best fit are linear equations.

Therefore, we can add the line of best fit to the graph (see attached), remembering to have roughly the same number of points above and below the line.

Linear equation:  y=mx+b

(where m is the slope and b is the y-intercept)

From inspection of the line of best fit, we can see that the y-intercept (where x = 0) is approximately 8.  So this suggests that options C or D are the solution.

We can also see that the slope (gradient) of the line of best fit is approximately -0.5 (as the rate of change (y/x) is -1 unit of y for every +2 units of x).

Therefore, C is the solution, and the closet approximation to the line of best fit is y=-0.5x+8
