Answer 2

Answer:

Answer:

Step-by-step explanation:

Please, include the instructions.

I'm assuming you want to solve this system of linear equations for z and w, assuming that k is an unknown constant.

Use the method of elimination by addition and subtraction. To eiiminate w, multiply all four terms of the first equation by 10, obtaining:

10 z + 10w - 30 = 10k

6z - 10 w = 80

Then 16z - 30 - 80 = 10k, or

16z -110 = 10k, Simplifying this, we get:

10(k + 11)

z = ---------------

Substituting this expression for z into the first equation, we get:

(10/16)(k + 11) + w - 3 = k. We must solve this for w:

-(10/16)(k + 11) + w - 3 = k), or

-(10/16)(k + 11) - w + 3 = -k

Then -(10/16)(k + 11) + 3 + k = w

and so the solution, in terms of the unknown constant k, is

10(k + 11)

( --------------, -(10/16)(k + 11) + 3 + k )

Answers

the equation of a cirecle with radius r and center at (h,k) is
(x-h)^2+(y-k)^2=r^2
r=10
center=(-2,-4)
(x+2)^2+(y+4)^2=10^2
(x+2)^2+(y+4)^2=100
(x,y)
sub given points (or use TI) and see if you get a true statmeent
A is on it

answer is A

the equation of of circle = (x+2)^2 + (x+4)^2 = 100
by sub. by this points in the circle equation
for point V(8,-4)
(8+2)^2 + (-4+4)^2 = 100
so the point V lay on the circle

A pair of equations is shown below. x + y = 5
y = one halfx + 2

If the two equations are graphed, at what point do the lines representing the two equations intersect?

(2, 5)
(5, 2)
(2, 3)
(3, 2)

Answers

The correct answer for the question that is being presented above is this one:

x + y = 5

y = one halfx + 2
y = 1/2 x + 2
-1/2 x + y = 2

Eliminate y by subtracting the two equations.
x + y = 5
-1/2 x + y = 2
----------------------
3/2 x = 3
3x = 6
x = 2

x + y = 5
2 + y = 5
y = 5-2
y = 3

So, the answer is (2,3).

C. Because the full length is 44. Now the equation is 6x-5=44. Add 5 to both sides. 6x=49. 49/6= 8.16666666666 so you round and get 8.17
