Hello :
<span>(x + 2)² + (y-3)² = 9²
the center is : R(3 , 0 ) and radius r = 9
the </span> point D is on the interior if : RD <span>< 9
</span>the point D is on the exterior if : RD > 9
the point D is circumference of the circle if :RD = 9
Answer:
x=30
Step-by-step explanation:
The two angles are supplementary. They add to 180
4x+20 + 40 =180
Combine like terms
4x+60 =180
Subtract 60 from each side
4x+60-60 = 180-60
4x = 120
Divide each side by 4
4x/4 = 120/4
x = 30
3x-10+2x=115
5x-10=115
5x=125
x=25
m<b=3(25)-10=65
m<C=2×25=50
Answer: -1
Step-by-step explanation:
f(t) = -2t + 3
f(-2) = -2 x -2 + 3 [ substituting the value]
f(-2) = -4 + 3
f(-2) = -1
Answer:
663.4
Step-by-step explanation:
1.55 x 10 = 15.5
4.28 x 10 = 42.8
42.8 x 15.5 = 663.4
