-x^2=23 in standard form

Mathematics
1 answer:
Korvikt [17]3 years ago
5 0
Add x^2 to both sides to get

-x^2 = 23

-x^2+x^2 = 23+x^2

0x^2 = x^2 + 23

0 = x^2 + 23

x^2 + 23 = 0

Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s).
Mashcka [7]

Multiplying eqn no. two with 4 we add it up with eqn 1.

4x - 5y = 10 \\  - 4x - 12y = 32 \\

- 17y = 42 \\ y =  \frac{ - 42}{17}

When

- x - 8 = 3y \\ x + 3y =  - 8

x =  - 8 -  3 \frac{ - 42}{17 }  \\ x =  - 8 +  \frac{42}{17}  \\ x =   \frac{ - 10}{17}

So, x = - 10/17 and y = - 42/17.

Marquise has 200200200 meters of fencing to build a rectangular garden.
Lera25 [3.4K]

Answer:

2500 Square meters

Step-by-step explanation:

Given the garden area (as a function of its width) as:

A(w)=-w^2+100w

The maximum possible area occurs when we maximize the area. To do this, we take the derivative, set it equal to zero and solve for w.

A'(w)=-2w+100

-2w+100=0

-2w=-100

w=50 meters

Since Marquise has 200 meters of fencing to build a rectangular garden,

Perimeter of the proposed garden=200 meters

Perimeter=2(l+w)

2(l+50)=200

2l+100=200

2l=200-100=100

l=50 meters

The dimensions that will yield the maximum area are therefore:

Length =50 meters

Width=50 meters

Maximum Area Possible =50 X 50 =<u>2500 square meters.</u>

P/-8 + 9 &gt; 13 <br> pls explain i don't get it
KonstantinChe [14]

Answer:

p < -32

Step-by-step explanation:

<em>Given:</em> p/-8 + 9 > 13

<em>Rewrite:</em> \frac{p}{-8} + 9 > 13

<em>Subtract 9 from both sides:</em> \frac{p}{-8}  > 4

<em>Move the negative (it is a fraction): </em>\frac{-p}{8} > 4

<em>Multiply both sides by 8:</em> -p > 32

<em>Times by -1 (-p -> -1p): </em>p > -32

<em>Flip the sign (multiplied by a negative): </em>p < -32

Hope this helps, have a nice day :D
