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

18% of what number is 7.2?
RUDIKE [14]
18% of 40 is 7.2

Change the percentage (18%) into a decimal by dividing it over 100:

18/100 = 0.18

Divide 7.2 by the decimal (0.18):

7.2 / 0.18 = 40

Explain two ways you could solve 20 = 5(−3 + x
emmasim [6.3K]

Answer:

7 is x

Step-by-step explanation:

1) Divide both sides by 5 to give

4=-3+x

x=4+3

x=7

2) Multiply 5 with the RHS (Right Hand Side) to give

20=-15+5x

20+15=5x

35=5x

x=7
