This system of equations has an infinite number of solutions. Define the solutions algebraically, and allow z to represent all r

Soloha48 [4]

Answer:

x = 12z + 1 and y = 10z - 1

Step-by-step explanation:

To solve the system of equations, we can use the substitution method

If we call

3x - 4y + 4z = 7 I

x - y - 2z = 2 II

2x - 3y + 6z = 5 III

Clearing II x = 2 + y + 2z

Now, replacing II in III

2(2 + y + 2z) - 3y +6z = 5

4 + 2y + 4z - 3y + 6z = 5

10z - y = 1 from here y = 10z - 1

Finally, replacing y in I

3x - 4(10z - 1) + 4z = 7

3x -40z + 4 + 4z = 7

3x - 36z = 3

3x = 36z + 3

x = 12z + 1

Find the equation of a circle with a point at ( 10 , - 4 ) and a point at ( -2 , - 4 )

astra-53 [7]

Answer:

Solution given:

letA=(10,-4)

B=(-2,-4)

centre[C](h,k)= $\frac{10-2}{2},\frac{-4-4}{2}=(+4,-4)$

radius= $\sqrt{(4-10)²+(-4+4)²}=6$ units

we have

Equation of a circle is;

(x-h)²+(y-k)²=r²

(x-4)²+(y+4)²=36

or.

x²-8x+16+y²+8y+16=36

x²-8x+8y+y²=36-32

x²-8x+8y+y²=4

The equation is (x-4)²+(y+4)²=36 or x²-8x+8y+y²=4.
