Answer:

y = 1/4 x - 7/2

Step-by-step explanation:

x - 4y = 14

-4y = -x + 14

y = -x/(-4) - 14/4

y = 1/4 x - 7/2

11−.5y=3+6x<br><br> The .5 is actually a fraction 1/2
maria [59]

Answer:

-12x+16=y

Step-by-step explanation:

Subtract 3 from 11: 8-0.5y=6x

Move 0.5y to the right side: 8=6x+0.5y

Move 6x to the left side: -6x+8=0.5y

Divide both sides by 0.5: -12x+16=y

The question I need is question #13. Please provide a step by step answer. Thank You
Jet001 [13]

Answer:

Step-by-step explanation:

We have plane 1 flying SW for 4 hours at a rate of 415 mph.  The distance he covers using the d = rt formula for distance, is 415(4) = 160 miles.

We also have plane 2 flying directly east (along the x-axis) for 4 hours at 327 mph.  The distance he covers using the d = rt formula for distance, is 327(4) = 1308 miles.  The angle in between them at this point is 135 degrees, and what we need to find is the length of the vector connecting the 2 planes.  IF this was right triangle trig that distance would be the hypotenuse and we could solve for it using Pythagorean's Theorem.  BUT it is NOT a right triangle, so we have to find some other means with which to solve for that length.  We will use the Law of Cosines to do this.

?^2=1660^2+1308^2-2(1660)(1308)cos(135) which simplifies a bit to

?^2=2755600+1712864-(-3070653.624)

If you add all of that together, you'll get

?^2=7537117.624  and you'll take the square root of that to get that the distance between the 2 planes after 4 hours is

2745 miles
