Answer:
0.72 ; 0.799 ; 0.8 ; 0.9
Step-by-step explanation:
4/5 = 0.8
9/10 = 0.9
Ascending order:
0.72 ; 0.799 ; 0.8 ; 0.9
First compare the tenth places. If tenth places are same, compare hundredth places
Answer:
(-3, 1), 5
Step-by-step explanation:
x² + y² + 6x - 2y - 15 = 0
Rearrange:
x² + 6x + y² - 2y = 15
Complete the square:
x² + 6x + 9 + y² - 2y + 1 = 15 + 9 + 1
(x + 3)² + (y - 1)² = 25
Therefore, the center is (-3, 1) and the radius is 5.
2^(1/2) is the same thing
X=0
Y=-2
Multiply the top equation by -2 to get -2y=-8x+4
Isolate 2y on the bottom by subtracting 3x from both sides to get 2y = -4 - 3x
Add the two equations get 0=-11x so x = 0
Solve for y by plugging zero into one of the equations to get y=4(0)-2 to find the y = -2
y=4(0)-2
Lets smaller number is x
<span>The greater number is 8 more than the smaller number : x + 8
</span><span>The sum of two numbers is 72: x +( x + 8)= 72
answer
</span><span>x + (x + 8) = 72</span>
