iren [92.7K]

Answer:

z=3

Add 3z and 2z

5z-5=25-5z

Add 5z on both sides to eliminate the -5z on the RHS

10z-5=25

Ivahew [28]

Answer: D.

Step-by-step explanation: Add all of the sides' lengths together. The rest of the wall beneath where "5 ft." is measures as 6 ft.

please help: What is the equation of a line parallel to -5x + y= 2 that passes through the point with coordinates (-2, 1)?
weqwewe [10]

Answer:

  • y = 5x + 11 or -5x + y = 11

Step-by-step explanation:

<u>Given line:</u>

  • -5x + y = 2

<u>In slope-intercept form:</u>

  • y = 5x + 2

<u>The parallel line has the same slope and will look as:</u>

  • y = 5x + b

<u>This line passes through the point (-2, 1), substitute:</u>

  • 1 = 5*(-2) + b
  • b = 1 + 10
  • b = 11

<u>So the line is:</u>

  • y = 5x + 11

or

  • -5x + y = 11
