C. 5x+7=22 since diameter is equal to double the radius. radius=11 so diameter equals 22. then just make 5x+7 = to 22
Answer:
x=10;y= -8
Step-by-step explanation:
A: x+y=2
B: -3-y=5 ---> y=-3-5=-8
so
A is : x+(-8)=2
x=2-(-8)=2+8=10
KMN = 90° (tangent perpendicular to radius)
Using Pythagoras Theorem,
√(8^2 + 6^2) = √(100) = 10
Therefore KN = 10km
Answer:
y=4x -9
Step-by-step explanation:
y intercept- where the line crosses the y-axis (-9)
Rise over run- 4
Applying the distance formula, to calculate the coordinates of B, use: 3 =√[(x-4)² + (y-2)²]
<h3>What is the Distance Formula?</h3>
The distance formula,
, is used to find the distance between two points on a coordinate plane.
We are given one point A(4, 2), let:
B (x, y) = (x2, y2)
A(4, 2) = (x1, y1)
d = 3 units
Plug in the values into the distance formula to find how to calculate the coordinates of B:
3 =√[(x-4)² + (y-2)²]
