Answer:
15÷1 .50=10
Because you are already paying a flat rate of $15. You make 1.50 off of each flower. So you have to sell over 10 flowers to make a profit.
we use the angle- sum and difference trigonometric identity to simplify the expression sin(3pi - x). This is equal to sin 3 pi cos x - cos 3 pi sin x. In this case, sin 3 pi is equal to zero while cos 3 pi is equal to -1. Hence the answer simplified is equal to sin x .
-8x - 2y = -4
When y = -5x
-8x - 2(-5x) = -4
- 8x + 10x = -4
2x = -4
x = -4/2 = -2
Answer:
Step-by-step explanation:
hello :
x²+ y² + 6x - 4y - 27 = 0 means : (x²+6x+9)-9+(y²-4y+4)-4-27 =0
(x+3)²+(y-2)² = 40....standard form when the center is (-3 , 2) and radius √40
