Use the substitution method by using all of the coordinates into y=-2x-8

(-8,8)

y=-2x-8

8=-2(-8)-8

do the bracket first

8=16-8

8=8

(-6,2)

2=-2-(6)-8

2=12-8

2=4

(-2,4)

4=-2(-2)-8

4=4-8

4=-4

(0,-4)

-4=-2(0)-8

-4=-8

(2,-12)

-12=-2(2)-8

-12=-4-8

-12=-12

Answers:

(–8, 8) and (2, –12)

The cost function in a computer manufacturing plant is C(x) = 0.28x^2-0.7x+1, where C(x) is the cost per hour in millions of dol
Licemer1 [7]

9514 1404 393

Answer:

  $562,500 per hour

Step-by-step explanation:

The cost will be a minimum where C'(x) = 0.

 C'(x) = 0.56x -0.7 = 0

  x = 0.7/0.56 = 1.25

The cost at that production point is ...

  C(1.25) = (0.28×1.25 -0.7)1.25 +1 = -0.35×1.25 +1 = 0.5625

The minimum production cost is $562,500 per hour for production of 1250 items per hour.

_____

<em>Additional comment</em>

This is different than the minimum cost <em>per item</em>. This level of production gives a per-item cost of $450. The minimum cost per item is $358.30 at a production level of 1890 per hour.

Shirley is going to have her home painted. Tim"s painting charges $250 plus $14 per hour. Colorful paints charges $22 per hour.
Advocard [28]

It would take greater than 31.25 hours for Tim's price to be better. So in terms of whole hours it would take at least 32 hours of work for Tim's price to be better.

What is the equation of a circle with center (-4,7) and a radius 6
s2008m [1.1K]

Answer:

( x +4)^2 + ( y-7)^2 = 36

Step-by-step explanation:

We can write the equation of a circle as

( x-h)^2 + ( y-k)^2 = r^2

where ( h,k) is the center and r is the radius

( x- -4)^2 + ( y-7)^2 = 6^2

( x +4)^2 + ( y-7)^2 = 36
