Can anyone help? <br><br> If arcLM = 8x-56 and arcNP = 5x+22, find arcLP.
Mashcka [7]

Answer:

arcLP = 19

Step-by-step explanation:

Given the following

arcLM = 8x-56

arcNP = 5x+22

Required

arcLP

Given that arcLM = arcNP

8x-56 = 5x+22

8x - 5x  = 22 + 56

3x = 78

x = 78/3

x = 26

Let assume arcLP = x - 7

arcLP = 26 -7

arcLP = 19

-3x+3y=12
max2010maxim [7]

Answer:

C

Step-by-step explanation:

  1. Reform the first graph: -3x + 3y = 12; 3y = 12 + 3x; y = 4 + x; y = x + 4
  2. Compare y = x + 4 and y = x + 4: they are equal, thus the same slope (1) and the same y-intercept (4)
