Answer:
-p^3
Step-by-step explanation:
( p - 2 p ) ^ 3
combine p and 2p to get -p
》expand (-p)^3
》(-1)^3p^3
calculate -1 to the power of 3 and get -1
and this equals -p^3
Answer:
5y+8(x-3y)=7x-12
5y+8x-24y=7x-12
8x-7x + 5y-24y= -12
X - 19y = - 12
9x+3(x-9y) =11y+46
9x+3x - 27y = 11y + 46
12x -27y - 11y = 46
12x - 38y = 46
Now joining together
X - 19y = - 12
12x - 38y = 46
Multiple by 12 the first equation and Substract after
12x - 228y = -144
12x - 38y = 46
- 190y = -98
Y = 1.9
12x - 38y = 46
12x - 38(1.9) = 46
12x - 73.67 = 46
12x = 46 + 73.67
12x = 119.67
X = 9.97
So the answer are :
X = 9.97
Y = 1.9

Answer:
Step-by-step explanation:
The inverse of a function, is the function or rule formed by reflecting the line over y=x. This means essentially that all (x,y) values from the original function switch to (y,x).
(x,y)--->(y,x) in the new function.
If the function has points (-3,4) and (5,-2) then the inverse has points (4,-3) and (-2, 5).
We can find the equation of the inverse by switching x and y in the equation and solving for y.
This means that 
becomes 
. We now solve for y through inverse operations.

Answer:
12 cm
Step-by-step explanation:
The square of the length of the tangent segment is equal to the product of near and far distances to the circle from the point of intersection of the secant and tangent:
(8 cm)^2 = (4 cm)(4 cm +x)
16 cm = 4 cm +x . . . . . . divide by 4 cm
12 cm = x . . . . . . . . . . . . subtract 4 cm
