Answer:
y = 2x + [-3]
Step-by-step explanation:
Slope of the perpendicular line = m = 2
Point = (x,y) = (6,9)
So, x = 6, y = 9
Putting in slope intercept equation
![y=mx+c](https://tex.z-dn.net/?f=y%3Dmx%2Bc)
9 = (2)(6) + c
c = 9-12
c = -3
Putting m and c in slope intercept equation
y = 2x + [-3]
You multiply 120 by 0.60 and you would get 72
Answer:
radius = 5 units
area of a circle = 15.7units²
Step-by-step explanation:
given that the circumference of a circle = 31.4
radius = ?
recall that the formulae for finding the circumference of a circle = 2πr
circumference of a circle = 2 x 3.14 x r
31. 4 = 6.28r
divide both sides by the coefficient of r which is 6.28
31.4/6.28 = 6.28r/6.28
5 = r
radius = 5 units
therefore the radius of the circle whose circumference is 31.4 units is evaluated to be 5units
to find the area of the circle
recall the formula = πr²
area of a circle = 3.14 x 5²
area of a circle = 3.14 x 25
area of a circle = 15.7units²
If you are talk about a line segment, it would contain two points.
If your talking about a ray, it would contain 1 point.
If your talking about just the line, it would contain no points.
The first one is negative one property of division, I think.
The second one is commutative property of multiplication.
