Answer:
-1/5
Step-by-step explanation:
(10 ,9) .....(40 , 3)
(9-3)/(10-40)=6/-30=-1/5
Note that [ (2x)^x ]^(1/x) = 2x, and that [ (2x)^(2x) ]^(1/x) = (2x)^2 = 4x^2
Multiplying these 2 results together, we get (2x)(4x^2) = 8x^3 (answer)
Answer:
60
Step-by-step explanation:
Answer:
x =3, y =3
Step-by-step explanation:
From the second equation( y= -x+6) we can get x alone.
Subtracting 6 from both sides we get, y-6 = -x
And then dividing both sides by -1, -y+6 = x
Then we can substitute this value of x into the first equation.
y = 2(-y+6) +3
Simplifying,
y = -2y + 12+ 3
3y = 15
y = 3
Substituting this back into second equation we get 3 = -x + 6
and -x = -3
Dividing both sides by -1,
we get x =3
