Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
3 ÷ x = 6
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Multiplication Property of Equality] Multiply <em>x</em> on both sides: 3 = 6x
- [Division Property of Equality] Divide 6 on both sides: 3/6 = x
- Simplify: 1/2 = x
- Rewrite: x = 1/2
<u>Part 1: Finding radius</u>
The radius of a circle is defined as the distance from the center to a point on the circle's circumference.
Using the distance formula,
<u>Part 2: Finding the point with x-coordinate -15</u>
Let the y coordinate of the point be y. Then, we have the point (-15, y). Substituting into the distance formula,
Answer:
5x-2y=-20
Step-by-step explanation:
y-y1=m(x-x1)
y-5=5/2(x-(-2))
y-5=5/2(x+2)
y-5=5/2x+10/2
y-5=5/2x+5
y=5/2x+5+5
y=5/2x+10
y-5/2x=10
-5/2x+y=10
2(-5/2x+y)=2(10)
-10/2x+2y=20
-5x+2y=20
5x-2y=-20
