Answer: Yes
Step-by-step explanation: Yup yup yup
Equation is :
( x + 2 )² + ( y - 1 )² = r²
( - 4 + 2 )² + ( 1 - 1 )² = r²
4 = r², than we will plug in to a formula:
( x + 2 )² + ( y - 1 )² = 4
x² + 4 x + 4 + y² - 2 y +1 = 4
x² + y² + 4 x - 2 y + 1 = 0
Answer: B )
Answer:
x+y=30
2x+3y=80
multiplying equation one by -3 and add equation
-3x -3y=-90
2x +3y=80
2(10)+20(3)=80
80=80
Answer:
8 units
Step-by-step explanation:
The area of a triangle is given by
A = 1/2 bh where b is the base and h is the height
16 = 1/2 (4)*x
16 = 2x
Divide each side by 2
16/2 = 2x/2
8 =x
