Elimination using addition and subtraction. <br> -4x+4y=-20<br> -2x+4y=-2
goldfiish [28.3K]

I would subtract the 2nd from the first one

so -4x - -2x = -2x

4y - 4y = 0

-20 - -2 = -18


-2x = -18

now I would divide that by -2 to get the value for x

so no we have x = 9


now you just have to substitute that into one of the equations and simplify to get y


-2 X 9 + 4y = -2

-18 + 4y = -2

4y =16

y = 4

Suppose that the dollar cost of producing x radios is c(x) = 400 + 20x - 0.2x 2. Find the marginal cost when 30 radios are produ
My name is Ann [436]
C(x) = 400 + 20x - 0.2x²

c(30) = 400 + 20(30) - 0.2(30)²

= 400 + 600 - 0.2(900)
= 1000 - 180
= 820

It costs $820 when 30 radios are produced. 

Marginal cost is how much it would cost to make one MORE of the same product so now we find how much it costs to produce 31 radios and compare the two. 

c(31) = 400 + 20(31) - 0.2(31)²

= 400 + 620 - 0.2(961)
= 1020 - 192.2
= 827.8 or ≈828.

Now we find the difference which means we subtract the two. 

828 - 820 = 8. 

Your marginal cost is $8. 

To compare we can also do 29 radios. 

c(29) = 400 + 20(29) - 0.2(29)² = 811.8 or ≈812

820 - 812 = 8.

Round 62,686 to nearest hundredth
Semenov [28]

Answer: 62.7 is rounded to the nearest hundredth.

Step-by-step explanation:

Because...

if you look at the 6 at the hundredth place then you have to look at the number next to it, which is 8 and since it's 5 and greater it the 6 becomes a 7 and therefor, the answer is 62.7.

* Hopefully this helps:) Mark me the brainliest:)!!
