what is: x + 3 - 2x -1 = 4 5 3
Answer:
X= -46/7
Step-by-step explanation:
step1: left part times 15 is 3(X+3)-5(2X-1)
step2: right part times 15 is 60
step3: 3(X+3)-5(2X-1)=60
step4: 3X+9-10X+5=60
step5: -7X+14=60
step6: -7X=46
step7: X= -46/7
B.) y = -2
C.) x = -2
D.) x = -1
Answer:
A.) y = -1
Step-by-step explanation:
The equation of a horizontal line is ...
y = constant
To make that line go through the point (x, y) = (-2, -1), the constant must match the y-coordinate of the point: -1.
y = -1
Equation given in the question represents a circle.
Therefore, there will be infinite lines of symmetry.
Given in the question,
Equation given in the question is in the form of
Since, general equation of a circle is given by,
Therefore, given equation represents a circle.
By definition, a circle has infinite lines of symmetry passing through the center.
Therefore, given equation will have infinite lines of symmetry.

Answer:
It has infinitely many line of symmetry. All diameters are line of symmetry.
Step-by-step explanation:
Given: Equation is x² + y² = 9
To find: line of symmetry of given equation
Given equation is the equation of circle.
x² + y² = 9
re write,
(x-0)² + (y-0)² = 3²
by comparing given equation with standard equation of circle ,
(x-h)² + (y-k)² = r²
we get, h = 0 , k = 0 , r = 3
⇒ Centre of circle = ( 0 , 0 ) and radius of circle = 3 unit
Since It is a circle. so it has Infinitely many line of symmetry
Also, All diameters of this circle are line of symmetry for this circle.
Some equation of line of symmetry,
