Answer:

y=2x-10

Step-by-step explanation:

2x - y=10

Subtract 2x from both sides

Robert stands atop a 1,380-foot hill. He climbs down, reaching the bottom of the hill in 30 minutes. What is Robert’s average ra
Zigmanuir [339]

Answer:

-46 feet/min

Step-by-step explanation:

Initial elevation = 1,380 ft

Final Elevation = 0 feet

Change in elevation

= Final elevation - Initial Elevation

= 0 - 1,380

= - 1,380 feet

Given that the journey took 30 min,

rate of descent = Change in elevation / time

= -1,380 / 30

= - 46 feet/min

A line is perpendicular to y = -x + 1
frozen [14]

Answer:                                                                                                              The equation of the perpendicular line intersects the point (-5,1) is  y=x+6[/tex]

Step-by-step explanation:

step1:-

The standard form of slope - intercept form y=m x+c

Here m is called slope of the given line

C is called the y- intercept of the given line

Given equation of the straight line y=-x+1

comparing  the slope - intercept form y=m x+c

here m= -1 and c=1

step2:-

The equation of the perpendicular line is

y-{[y_{1}} =\frac{-1}{m} (x-x_{1} )[/tex]

substitute m =  -1 and c =1 values  in equation

y-1 =\frac{-1}{-1} (x-(-5 )

y-1 ={1} (x-(-5 )

y=1+x+5\\y=x+6

step3:- The equation of the perpendicular line intersects the point (-5,1) is

y=x+6[/tex]

<u>conclusion</u><u>:</u>-

The equation of the perpendicular line  is

y=x+6[/tex]
