If |4x - y =1

Mathematics
1 answer:
Allushta [10]3 years ago
8 0

Answer:

  • x = 2
  • y = 7
  • x - y = -5

Step-by-step explanation:

We have been two algebraic expressions which is given below:

  • 4x - y = 1
  • 3x + 2y = 20

We have to find the value of x - y. so we need to find the value of x and y.

4x - y = 1 * 3

3x + 2y = 20 * 4

  • 12x - 3y = 3
  • 12x + 8y = 80

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

-11y = - 77

y = 77/11

y = 7

  • <u>Substitute the value of y in equation 1.</u>

4x - y = 1

4x - 7 = 1

4x = 1 + 7

4x = 8

x = 8/4

x = 2

  • x - y
  • 2 - 7 = -5
  • Therefore, the required value of x, y , and x - y are 2,7 and -5 respectively.

find the coordinates for the center of a circle with a diameter having endpoints at (0,2) and (-9,-2)
Fittoniya [83]

Answer:

(x−2)2+(y+1)2=100

Explanation:

the standard form of the equation of a circle is  

2 2 ( x − a ) 2 + ( y − b ) 2 = r 2 2 2  where  ( a , b )  are the coordinates of the center and r is  the radius  to find the center we require the  midpoint of the  2 given points  center  = [ 1 2 ( − 4+ 8 ) , 1 2 ( 7 − 9 ) ]  center = ( 2 , − 1 )  the radius is the distance from the center to either of  the 2 given points  calculate the radius using the  distance formula ∙  d = √ ( x2 − x 1 ) 2 + ( y 2 − y 1 ) 2  let  ( x 1 , y 1) = ( 2 , -1 )  and  ( x 2 , y 2 ) = ( − 4 , 7 ) r = √ = √ ( − 4 − 2 ) 2 + ( 7 + 1 ) 2 = √ 36 + 64 = 10 ⇒ ( x − 2 ) 2 + ( y − ( − 1 ) ) 2 = 10 2 ⇒ ( x − 2 )2 + ( y + 1 ) 2 = 100 ←  equation of circle
