Genghis Motors wants to build cars and motorbikes on a budget. The company plans to spend at most $75000 and use at least 320 wo
Sergio [31]
Evaluate each of the expressions for the given values of the variables and see if the condition is met.

8000*4 +5500*6 = 65000 ≤ 75000 . . . true

52*4 +38*6 = 436 ≥ 320 . . . . . . . . . . . . . true

Yes, the company can meet both its expectations by building 4 cars and 6 motorbikes.

Of course, another way to work this is to draw the graph and see if the offered point is in the feasible region. It is.

One student begins in Cleveland, Ohio, and walks towards Buffalo, New York, a distance of 200 miles. She walks at the rate of 2.
omeli [17]
Ok so student in cleveland walks 2.5 miles away from cleveland every hour from 8
so the distance, x is x=2.5t

the riding one rides 4 hours later, so t-4
11 mph
y=11(t-4)

A. x=2.5t
y=11(t-4)

when do they meet is when the distance when they are equal or when x=y
2.5t=x=y=11(t-4)
solve for t
2.5t=11(t-4)
2.5t=11t-44
-8.5t=-44
divide both sides by -8.5
t=5.17647

answer is 5.18 hours


A.
x=2.5t
y=11(t-4)

B. 5.18 hours

Given line y-1/6x+9,find a perpendicular line to the given line passes through points (6,-3)?
DerKrebs [107]

Answer:

y + 3 = (6)(x - 6)

Step-by-step explanation:

The proper format for this equation y-1/6x+9 is y = (-1/6)x+9.

Any line perpendicular to y = (-1/6)x+9 has the slope which is the negative reciprocal of that of y = (-1/6)x+9, or the negative reciprocal of -1/6.  That is +6.  

Thus, the desired line, which passes through (6, -3), is found using the point-slope formula for the equation of a straight line:

y + 3 = (6)(x - 6)
