Answer:
14 square units
Step-by-step explanation:
Solve for x and y
6/x+2y + 5/x-2y = -3 ;
3/x+2y + 7/x-2y = -6
Step-by-step explanation:
Let
{1/(x+2y)} = u -----Eqn(1)
{1/(x-2y)} = v ------Eqn(2)
So, given equation can be rewritten as
⇛6u + 5v = -3 ---Eqn(3)
⇛3u + 7v = -6 -----Eqn(4)
On multiply equation (4) by 2, we get
⇛6u + 14v = -12 -----Eqn(5)
On subtracting equation (3) from equation (5), we get
⇛9v = -9
⇛v = -9/9
⇛v = -1 ----Eqn(6)
Put value of v in equation (3), we get
6u + 5v = -3
⇛6u + 5 * (-1) = -3
⇛6u -5 = -3
⇛6u = -3 + 5
⇛6u = 2
⇛u = 2/6
⇛u = (2÷2)/(6÷2)
⇛u = 1/3 -----Eqn(7)
Now, substituting value of u and v in equation (1) and equation (2), we get
{1/(x+2y)} = 1/3 and {1/(x-2y)} = -1
⇛x + 2y = 3 -----Eqn(8)
⇛x - 2y = -1 -------Eqn(9)
Now, add equation (8) and equation (9) , we get
⇛2x = 2
⇛x = 2/2
⇛x = 1 -----Eqn(10)On substituting x = 1 in equation (8), we get
x + 2y = 3
⇛ 1 + 2y = 3
⇛2y = 3 - 1
⇛2y = 2
⇛y = 2/2
⇛y = 1 ------Eqn(11)Therefore, x = 1 and y = 1
Answer: Hence the value of x and y is 1 and 1.

The solution of the simultaneous linear equations shown below is 2x - y=12 2x+y=13
Answer:
(6.25, 0.5 )
Step-by-step explanation:
2x - y = 12 → (1)
2x + y = 13 → (2)
Add the 2 equations term by term to eliminate y
4x + 0 = 25
4x = 25 ( divide both sides by 4 )
x = 6.25
substitute x = 6.25 into either of the 2 equations and solve for y
substituting into (2)
2(6.25) + y = 13
12.5 + y = 13 ( subtract 12.5 from both sides )
y = 0.5
solution is (6.25, 0.5 )

Find the elapsed time.
Start: 11:55 A.M.
End: 5:10 P.M.
Answer:
5 hours and 15 minutes
Step-by-step explanation:
From 11:55 A.M. to 12:00 P.M. is 5 minutes.
From 12:00 P.M. to 12:10 P.M. is 10 minutes.
From 12:10 P.M. to 5:10 P.M. is 5 hours.
If you add all of that up to get the time that has elapsed, you will get 5 hours and 15 minutes.

Circle T is defined by the equation (x + 5)2 + (y - 2) = 81. Which of the following shows the location of the center of Circle T and the radius of this
circle?
A T is located on (-5, 2); radius = 9 units
B T is located at (5,-2); radius = 9 units
C T is located at (-5, 2); radius = 81 units
D T is located at (5,-2); radius = 81 units
Answer:
A) T is located on (-5, 2); radius = 9 units
Step-by-step explanation:
eqn of circle= (x-a)^2 + (y-b)^2 = r^2
where (a,b) is centre of circle.
(x+5)^2 = (x - (-5) )^2
(y-2)^2 = (y - (2) )^2
(-5,2)
r^2 =81
r = sqrt of 81
r = 9

How to determine the result of a definite integral based on a formula and a table
This integral can be approximated by the following Riemann sum:
[tex]A = \Sigma\limits_{i=0}^{2} \left\{(x_{i+1}-x_{i})\cdot x_{i}\cdot h''(x_{i})+\frac{1}{2}\cdot (x_{i+1}-x_{i})\cdot [x_{i+1}\cdot h''(x_{i+1})-x_{i}\cdot h''(x_{i})] \right\}[/tex]
[tex]A = \frac{1}{2} \cdot \Sigma\limits_{i=0}^{2} \left\{(x_{i+1}-x_{i})\cdot [x_{i+1}\cdot h''(x_{i+1})+x_{i}\cdot h''(x_{i})] \right\}[/tex]
Then, the approximate value of the integral is:
[tex]A = \frac{1}{2}\cdot \{(2-1)\cdot [(2)\cdot 2+(1)\cdot (-5)]+(3-2)\cdot [(3)\cdot 1+(2)\cdot 2]+(4-1)\cdot [(4)\cdot 2+(3)\cdot 1]\}[/tex]
[tex]A = 8.5[/tex]
The value of [tex]\int\limits^{4}_{1} {x\cdot h''(x)} \, dx[/tex] is 8.5. The choice that represent the best approximation is A. [tex]\blacksquare[/tex]

Step-by-step explanation:
the sum of all the angles is 180° as it is a straight line.
so,
n + 6 + 90 + 2n + 3 = 180
3n + 99 = 180
3n = 180 - 99 = 81
n = 81/3 = 27
n = 27°
therefore, value of n is 27°.

Can someone explain just 17-28??
Answer:
you solve these by plugging the numbers into pythagorean theorem which is
a^2 + b^2 = c^2 (a squared plus b squared equal c squared)
C is the hypotenuse which is the longest side across from the right angel (assuming all these problems are for right triangles)
so 17 would be 9.5^2 + 3.8^2 = c^2
So 90.25 + 14.44 = c^2
104.69=c^2
Then to solve for c take the square root of each side and get
10.23=c
To do the other ones where a or b doesn’t have a value, it’s almost the same but you just have to plug in the variables in different places and solve it

The area of a rectangle is 5 x cubed 19 x squared 6 x minus 18 with length x 3. Using synthetic division, what is the width of the rectangle? 5 x squared 4 x minus 6 5 x squared 34 x 108 StartFraction 306 Over x 3 EndFraction 5 x cubed 4 x squared minus 6 x 5 x squared 34 x 108 StartFraction 306 Over x minus 3 EndFraction.
The area of the rectangle is the product of its dimensions.
The width of the rectangle is [tex]5(19x^2 + 6x - 18)[/tex]
How to calculate the width of the rectangleThe area of the rectangle is given as:
[tex]Area = 5x^3(19x^2 + 6x - 18)[/tex]
The length of the rectangle is given as:
[tex]Length =x^3[/tex]
So, we have:
[tex]Area = Length * Width[/tex]
Substitute known values
[tex]5x^3(19x^2 + 6x - 18)= x^3* Width[/tex]
Divide through by x^3
[tex]5(19x^2 + 6x - 18)= Width[/tex]
Rewrite the equation as:
[tex]Width = 5(19x^2 + 6x - 18)[/tex]
Hence, the expression that represents the width of the rectangle is [tex]5(19x^2 + 6x - 18)[/tex]
