Which of the following steps indicates the addition property of equality while solving the equation –1 – 6x = x – 15? Question 4

den301095 [7]

Answer:

B) -1-6 x +15 = x - 15 +15

Step-by-step explanation:

Explanation:-

Given equation is –1 – 6 x = x – 15

By addition property of equality

⇒ - 1 - 6 x + 15 = x - 15 +15

⇒ - 6 x + 14 = x

subtracting 'x' on both sides ,we get

⇒ - 6 x -x +14 =0

⇒ - 7 x +14 =0

⇒ -7 x = - 14

Dividing '-7' on both sides , we get

x = 2

The solution of given equation is x = 2

The diameter of a circle has length 12. The center is at*(-5, 2). Give the equation

labwork [276]

Answer:

Equation of the circle is : $x^{2} + 10x + y^{2} -4y -7 =0$

Step-by-step explanation:

Let us consider the image attached in the answer area.

The center O has the co-ordinates i.e. (-5,2) and the diameter given is 12 units.

We know that radius is half of diameter.

$\text{Radius = }\dfrac{\text{Diameter}}{2}$

$\text{Radius = }\dfrac{12}{2}\\\Rightarrow \text{Radius = 6units}$

The equation for circle given the center and radius, can be represented as:

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

Where (a,b) is the co-ordinate of center and r is the radius.

Let us consider the following formula:

$(p+q)^2 = p^{2}+ q^{2} +2pq\\(p-q)^2 = p^{2}+ q^{2} -2pq$

$(x-(-5))^{2}+ (y-2)^{2} = 6^{2}\\\Rightarrow (x+5)^{2}+ (y-2)^{2} = 36\\\Rightarrow x^{2} + 25 + 10x +y^{2} + 4-4y=36\\\Rightarrow x^{2} + 10x +y^{2} -4y-7=0$

Hence, Equation of the circle is : $x^{2} + 10x + y^{2} -4y -7 =0$

Which inequality is equivalent to -6x

Papessa [141]

Step-by-step explanation:

How to simplify

-6x (some sign, it didn't show in the question)30

Divide by -6 on both sides to isolate the variable.

30 divided by -6 is -5, so x=-5.
