Answer:

-9x

Step-by-step explanation:

Without the confusing parentheses, this "polynomial" becomes -8x + x -2x. If we take 2 away from -8, it becomes -10. If we add a positive x, it becomes -9x. Therefore, the answer is (the monomial) -9x.

Answer:

The correct answer is -9x

Step-by-step explanation:

It is given a polynomial,

p(x) = (-8x) + x + (-2x)

<u>To simplify p(x)</u>

p(x) = (-8x) + x + (-2x)

= -8x + x - 2x

= -8x - 2x + x

= -10x + x

= -9x

(-8x) + x + (-2x) = -9x

Therefore the correct answer is -9x

What is the slope of the line with equation y-3=-1/2(x-2)?

ludmilkaskok [199]

Answer:

slope = - $\frac{1}{2}$

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

y - 3 = - $\frac{1}{2}$ (x - 2) ← is in point- slope form

with slope m = - $\frac{1}{2}$

F(x)=x^2 reflected over x=2

klasskru [66]

Answer:

please rate

Step-by-step explanation:

To reflect a graph, f(x) over the x-axis, you take -f(x). So if f(x)=x^2, then -f(x) is -x^2. Then g(x)=-x^2 is the reflection of your function f(x) over the x-axis.
