Solve the system of equations y = x + 5 and y = 5x - 11 using a graphical method. a) (4, 9) b) (9, 14) c) (9, 4) d) (14, 9)

You can use substitution for this.

x+5 = 5x -11

Combine like terms

16=4x

Divide 4 on both sides to isolate the x

x=4

Plug x=4 to one of the equations

y= 4 +5

Combine like terms

y=9

So the answer is A. (4,9)

I hope this helps you out a bunch hun :)

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
