Answer:

y = -27

Step-by-step explanation:

  • Multiply the entire equation by 6

         \sf 6*\dfrac{y+1}{3}-6*\dfrac{3y-1}{6}=6*5\\\\\\

             2*(y + 1) - (3y - 1 )    = 30

  •  Multiply (y +1) by 2 and (3y - 1) by (-1)

          2y + 2 - 3y + 1 = 30

  • Isolate y term by taking the constant term to RHS

                  2y - 3y = 30 - 2 - 1

  •  Combine like terms

                        -y      = 27

                             y = -27

Find the z score that cuts-off the largest 9% under the standard normal curve. a) -1.34 b) 1.34 c) 0.536 d) 1.28
topjm [15]

Answer:

b) 1.34

Step-by-step explanation:

The z score is used to determine the number of standard deviations by which the raw score is above or below the mean. If the z score is positive then the z score is above the mean while for a negative z score implies that it is below the mean. The z score is given by:

z=\frac{x-\mu}{\sigma}

For the largest 9%, the score is 100% - 9% = 91% = 0.91

From the normal distribution table, the z score that corresponds to 0.91 is 1.34

Find an equation of the line that bisects the acute angles formed by the lines with equations 2x+y-5=0 and 3x-2y+6=0
Neko [114]
The solving for the first one should be like this 

2x+y-5/sqrt 2^2 1^2=2x+y-5/sqrt5
And the next part 3x-2y+6/sqrt 3^2 -2^2=3x-2y+6/sqrt13

After these manipulations just multiply them 

(2sqrt13-3sqrt5)x+(sqrt13+2sqrt5) y-5sqrt13-6sqrt5=0 

And finally you need to square and simplify for the completed answer
