What is an equation of the line that passes through the point (−4,8) and is parallel to the line x+y=6? PLEASE

y = - x + 4

Step-by-step explanation:

x + y = 6

y = - x + 6

Slope= -1

Use the same slope since the two lines are parallel to each other.

Point-slope formula:

y - 8 = -1 (x - - 4)

y - 8 = -1 (x + 4)

y - 8 + 8 = -x - 4 + 8

y = - x + 4 (Slope-intercept form)

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
