Does the equation 6x+35=-6x+35 have infinitely many ,one or no solution​
marissa [1.9K]

Answer:

One solution

Step-by-step explanation:

6x+35=-6x+35

Add 6x to both sides (addition property of equality)

12x+35=35

Subtract 35 from both sides (subtraction property of equality)

12x=0

Divide both sides by 12 (division property of equality)

x=0

Therefore there is only one solution, 0.

The equation x^2 + y^2 + 21 = 40 + 18y. What is the radius of this cookie?​
trapecia [35]

Answer:

The radius is 10

Step-by-step explanation:

Given

x^2 + y^2 + 21 = 40 + 18y.

Required

The radius

Rewrite as:

x^2 + y^2 - 18y = 40-21

Subtract 81 from both sides

x^2 + y^2 - 18y +81= 40-21+81

Expand

x^2 + y^2 - 9y - 9y +81= 40-21+81

Factorize

x^2 + y( y- 9) - 9(y -9)= 40-21+81

Factor out y - 9

x^2 + (y- 9) (y -9)= 40-21+81

Express as squares

x^2 + (y- 9)^2= 100

x^2 + (y- 9)= 10^2

The equation of a circle is:

(x - a)^2 + (y- b)= r^2

By comparison:

r^2=10^2

r = 10
