Answer:

y>\frac{8}{3}

Step-by-step explanation:

\frac{3y-4}{0.2}-8>12\\\frac{3y-4}{0.2} > 20\\5(3y-4)>20\\3y-4>4\\3y>8\\y>\frac{8}{3}

Dividing by 0.2 is the same as multiplying by 5. Check your calculator if you don't believe me.

Jk + 4m/2 Can somone explain this to me please
Inessa05 [86]

Answer:

Since J = 3, K = 6, and M = 12, the equation means:


(3 • 6) + (4 • 12 ÷ 2) = ???

Step-by-step explanation:

This is because when variables are next to each other and we know what they are equal to, it is the same as saying 3 • 6. So, when two variables are next to each other, they are being multiplied. Same with 4m/2. / can also mean division. And since 4 is next to m, the two are being multiplied. All together, the answer to this equation is 42. Hope this helped!

Find all of the zeros of the function f(x)=x^3-17x^2+81x-65
viktelen [127]
A graph shows the function can be factored as
  f(x) = (x -1)((x-8)² +1)

There is one real root and there are two complex roots. The latter can be found from the vertex form factor:
  (x - 8)² + 1 = 0
  (x - 8)² = -1
  x - 8 = ±√(-1) = ±i
  x = 8 ± i

The zeros of the function are {1, 8-i, 8+i}.
