Solve the equation by completing the square

Answer:

= 1/x^2

Step-by-step explanation:

Possible derivation:

d/dx(-16 - 1/x + y)

Differentiate the sum term by term and factor out constants:

= d/dx(-16) - d/dx(1/x) + d/dx(y)

The derivative of -16 is zero:

= -(d/dx(1/x)) + d/dx(y) + 0

Simplify the expression:

= -(d/dx(1/x)) + d/dx(y)

Use the power rule, d/dx(x^n) = n x^(n - 1), where n = -1.

d/dx(1/x) = d/dx(x^(-1)) = -x^(-2):

= d/dx(y) - -1/x^2

Simplify the expression:

= 1/x^2 + d/dx(y)

The derivative of y is zero:

= 1/x^2 + 0

Simplify the expression:

Answer: = 1/x^2

Answer: 75

Step-by-step explanation:

Answer:

3 1/2

Step-by-step explanation:

Rewriting our equation with parts separated

=6+1/4−2−3/4=6+1/4−2−3/4

Solving the whole number parts

6−2=4/6−2=4

Solving the fraction parts

1/4−3/4=−2/4 1/4−3/4=−2/4

Reducing the fraction part, 2/4,

−2/4=−1/2−2/4=−1/2

Combining the whole and fraction parts

4−1/2=3 1/2

I hope this helps! have an amazing day!

Answer:

3/8

Step-by-step explanation:

(2/9 x 45/15) - 7/24

45/15 = 3

(2/9 x 3) - 7/24

2/9 x 3 = 6/9 = 2/3

2/3 - 7/24

2/3 = 16/24

16/24 - 7/24 = 9/24

9/24 = 3/8

sorry i don't really get this cause the way you explained it maybe in the comment section say it again and i might get it when you say it again.

Answer:

180 in^2

Step-by-step explanation:

area = 5(sq rt 75) x (sq rt 27) - [5(sq rt 75)-5(sq rt 27)] x 3(sq rt 3) x 0.5

area = 180 in^2

So, first you want to have 113 then you are going to want to divide it by pi or 3.14. After that, square it.

Your answer would be 6

Answer:

n = 84 and there are 24 blue cards

Step-by-step explanation:

I'm guessing you're either trying to find n or the number of blue cards.

To find the number of blue cards:

Luna has 60 red cards and the ratio of red to blue cards is 5:2.

If you divide 60 by 5 (the number of red cards divided by the ratio for red cards) you get 12, which would be 1 in the ratio. The number in the ratio for blue cards is 2, so multiply 12 by 2 and you get 24. Therefore, the number of blue cards is 24.

If the explanation is confusing (which I know it is, sorry) you can look at it like this, and this is also a check:

The ratio of red to blue cards can be written as 5/2. If you do 5 ÷ 2, you get 2.5 and if you divide 60/24, you get 2.5

To find n, the number of cards Luna has, just add the number of red cards and the number of blue cards: 60 + 24 = 84

Answer:

x = 36 degrees

Step-by-step explanation:

We can use exterior angles theorem to find that 140 degrees is equal to x plus 104 degrees. We subtract 104 degrees on both sides and get that x is 36 degrees.

Answer: She sold 2.68kg of apples in the market

Step-by-step explanation:

Weight of pears and apples= 6.7 kg

weight of pears = 3/5 x 6.7 kg= 4.02 kg

Weight  of apples = Total weight of the fruits -  weight of pears

= 6.70kg- 4.02kg =2.68 kg

Answer:

1 is the right answer

Answer:

Step-by-step explanation:

Hello,

I am pretty sure all this would be is :

Let c = Carlos's baseball cards

c = x + 8

Since Ben in this problem is irrelevant to Carlos, we just are using Adams cards and adding 8 onto them to find Carlos's cards since he has 8 more.

Since :

"Carlos has 8 more than Adam Write"

"Adam has x baseball cards"

So:

c = x + 8

I hope this helps!

Answer: uhhh sorry if it's wrong but i think its 14000  

Step-by-step explanation:

Step-by-step explanation:

Given

y = - 8 /5 x + 2

Comparing the given equation with y = mx + c

slope (m) = - 8/5

Hope it will help :)

Answer:

-8/5

Explanation:

The equation is written in slope-intercept form, aka y = mx + b, where m is the slope and b is the y-intercept.

In slope intercept, the slope is always the number that comes before x.

In the equation y = -8/5x + 2, that number is -8/5.

Hence, the answer is -8/5.

no solution i think hehe 0=0
