Answer:
(x+8)² + (y+9)² = 100
Step-by-step explanation:
The equation for a circle on a graph is
(x - a)² + (y - b)² = r²
r represents the radius
a represents the x displacement of the circle's center.
b represents the y displacement of the circle's center.
Answer:
1) First, add or subtract both sides of the linear equation by the same number.
2) Secondly, multiply or divide both sides of the linear equation by the same number.
3)* Instead of step #2, always multiply both sides of the equation by the reciprocal of the coefficient of the variable.
Step-by-step explanation:
Answer:
factoring / standard form
The area of a triangle can be found by using the formula A = bh/2
To find the area of the shaded region (the green section), we can find the area of both triangles and subtract.
Large triangle:
A = 28*36/2
A = 1008/2
A = 504km²
Small triangle:
A = 15*19/2
A = 285/2
A = 142.5km²
Subtract both triangles:
504 - 142.5 = 361.5km²
Therefore, the area of the shaded region is <u>361.5</u>km²
Best of Luck!
