3x^2/2250^3
</span>3 Take out the constants
3/2250 x x^2/x^3
4 Simplify 3/2250 to 1/750
1/750 x x^2/x^3
5 Simplify
x^2/750x^3
6 Use Quotient Rule: x^a/x^b = x^a-b
<span>x^2-3/750
</span>7 Simplify 2-3 to <span>-1
x^-1/750
</span>8 Use <span>Negative Power Rule: x^-a = 1/x^a
1/x /750
</span>9 Simplify
1/750x is the answer. :)
I hope this help[s. :)
Answer:
b x =-2/3
Step-by-step explanation:
-3(2x+1) + 3x = 6x + 3
Distribute
-6x -3 +3x =6x+3
Combine like terms
-3x-3 = 6x+3
Add 3x to each side
-3x+3x-3 = 6x+3x+3
-3 = 9x+3
Subtract 3 from each side
-3-3 = 9x+3-3
-6 = 9x
Divide by 9
-6/9 = 9x/9
-2/3 =x
Answer:
285°

Answer:
Center ( 4 , -2) and r = 6
Step-by-step explanation:
x² - 8x + y² + 4y - 16 = 0
x² - 8x + y² + 4 y = 16
x²- 2*4x + y² + 2 *2y = 16
(x² - 2*4x + 16 ) - 16 + (y² + 2*2y + 4) -4 = 16
(x - 4)² + (y + 2)² = 16 + 16 + 4
(x - 4)² + (y -[-2])² = 36
(x- 4)² + ( y - [-2] )² = 6²
Compare with (x - h)²+ (y - k)² = r²
Center ( 4 , -2) and r = 6
