Simplify this expression: (-2 - 8x) + (-4x - 10)
nevsk [136]

Answer:

The simplified form of expression<u> </u>(-2 - 8x) + (-4x - 10) is

-12(x + 1)

Step-by-step explanation:

It is given an expression (-2 - 8x) + (-4x - 10)

<u>To find the simplified expression of (-2 - 8x) + (-4x - 10)</u>

Let expression is given by

(-2 - 8x) + (-4x - 10) = -2 - 8x -4x -10

     = -2 -10 -4x -8x

     = -12 -12x

     -12(x + 1)   (since -12 is common in both terms)

Therefore simplified form is  -12(x + 1)

Write an equation in standard form of the parabola that has the same shape as the graph of f(x)=5x^2or g(x)=-5x^2, but with a gi
pickupchik [31]
F(x)=5x^2 Has minimum (0,0)

g(x) = f(x) + 2 Shifts the graph two units up, then the minimum is 2+0=2.

h(x) = g(x+4) Shifts the graph four units left,  then the minimum is at 0-4 = -4.

Then h(x) = 5(x+4)^2 + 2 has the minimum (-4,2)

And p(x) = -5(x+4)^2 + 2 has the maximum (-4,2)
