Step-by-step explanation:
(2x³y^-4)^-2 = 1/(4x⁶y^‐8) = y⁸/(4x⁶)
1/(8x⁵y^-7) = y⁷/(8x⁵)
4x^-9y⁴ = 4y⁴/x⁹
so, the whole expression is then
y⁸/(4x⁶) × y⁷/(8x⁵) × 4y⁴/x⁹
4y¹⁹/(32x²⁰) = y¹⁹/(8x²⁰)
so, D is the correct answer.
There is a difference of 14 units between -2 and 12. To find the coordinate in the middle, just add 7, half the distance between -2 and 12, to -2 and subtract 7 from 12. That gives you the coordinate 5.
Answer:
G=m/r-h^2
Step-by-step explanation:
move all the terms to the left side and set equal to zero. Then set each factor equal to zero. Hope this helps!
Answer:
z = - 1
Step-by-step explanation:
z + (z - 6) - 2 = - 10 ← remove the parenthesis on left side
z + z - 6 - 2 = - 10 , that is
2z - 8 = - 10 ( add 8 to both sides )
2z = - 2 ( divide both sides by 2 )
z = - 1
Answer:
(0.5, 5.5)
Step-by-step explanation:
So we know that one point is (-4, 6) and the other point is (3, 5). Also we know that Diagonals of a rhombus intersect at their midpoints.
For that reason, the point is:
x = (3 -4)/2=0.5
y=(5+6)/2 = 5.5
Then, the response is: (0.5, 5.5)
