Determine if the following system of equations has no solutions, infinitely many

Mathematics
1 answer:
DochEvi [55]2 years ago
8 0

Answer:

There is one solution

Step-by-step explanation:

2x + y = -1

8x + 3y = -2

Multiply the first equation by -4

-8x -4y = 4

Then add the equations together to eliminate x

-8x -4y = 4

8x + 3y = -2

--------------------

   -y = 2

Multiply by -1

y =-2

Now find x

2x+y =-1

2x+-2 =-1

Add 2 to each side

2x-2+2=-1+2

2x=1

Divide by 2

x = 1/2

Answer:

225 in.^3

Step-by-step explanation:

You need to find the volume of the container.

The container has the shape of a rectangular prism.

volume = length * width * height

volume = 5 in. * 4.5 in. * 10 in.

volume = 225 in.^3

What is the coordinate?
faltersainse [42]
Remember that the equation of a circle is:
(x - h)^{2} + (y - k)^{2} =  r^{2}
Where (h, k) is the center and r is the radius.
We need to get the equation into that form, and find k.

x^{2} - 6x +  y^{2} - 10y = 56

Complete the square. We must do this for x² - 6x and y² - 10y separately.

x² - 6x
Divide -6 by 2 to get -3.
Square -3 to get 9. Add 9,
x² - 6x + 9

Because we've added 9 on one side of the equation, we have to remember to do the same on the other side.

x^{2} - 6x + 9 + y^{2} - 10y = 65

Now factor x² - 6x + 9 to get (x - 3)² and do the same thing with y² - 10y.

y² - 10y
Divide -10 by 2 to get -5.
Square -5 to get 25.
Add 25 on both sides.

(x - 3)^{2}+ y^{2} - 10y + 25= 90

Factor y² - 10y + 25 to get (y - 5)²

(x - 3)^{2}+ (y - 5)^{2} = 90

Now our equation is in the correct form. We can easily see that h is 3 and k is 5. (not negative because the original equation has -h and -k so you must multiply -1 to it)

Since (h, k) represents the center, (3, 5) is the center and 5 is the y-coordinate of the center.

Question 4 of 25 Use the substitution method to solve the system of equations the correct ordered par x+y=5 y=7​
alex41 [277]

Answer:

x = -2

y = 7

Step-by-step explanation:

x+y=5

y=7​

x+y=5

x + 7 = 5

x = -2

x+y=5

-2 + y = 5

y = 7

Which rectangular equation is equivalent to the polar equation r csc theta=8?
Drupady [299]
Rectangular and polar forms are two forms of equations that translates to plot. In this case, the two forms are convertible to each other by the expressions:

r sin theta = y
r cos theta = x
x2 + y2 = r2

we are given the polar expression r csc theta = 8 and is asked to convert to rectangular form.

in this case, csc theta is equal to 1/ sin theta. thys
 r / sin theta = 8

in order to make use of the equations above, then

we multiply r to both numerator and denominator in the left side, that is 
r^2 / r sin theta = 8 
x2+y2 / y = 8
x  2 + y2 = 8y
