There are two like terms. 5n and -7n. And one that’s different. 7. Combining just means adding or subtracting. Add the 5n to -7n. And leave the +6. You got it.

Solve |2x - 2| < 8
Alex777 [14]

Answer:

C

Step-by-step explanation:

|2x - 2| < 8

it implies that

2x - 2 < 8

2x -2 + 2 < 8 + 2

2x < 10

x < 5

or

-(2x - 2) < 8

-2x + 2 < 8

-2x + 2 - 2 < 8 - 2

- 2x < 6

x > -3 ( the sense of the inequality reverse because I divided by minus)

The solution can be combine to

-3<x<5

Consider the following function. f ( x ) = 1 − x 2 / 3 Find f ( − 1 ) and f ( 1 ) . f ( − 1 ) = f ( 1 ) = Find all values c in (
Ksenya-84 [330]

Answer:

(E)Nothing can be concluded.

Step-by-step explanation:

Given the function f(x)=1-x^{\frac{2}{3}}

f(-1)=1-(-1)^{\frac{2}{3}}=1.5-0.86603i\\f(1)=1-1^{\frac{2}{3}}=1-1=0

f'(x)=-\dfrac{2}{3}x^{-\frac{1}{3}}\\f'(x)=-\dfrac{2}{3\sqrt[3]{x} }

If the derivative is set equal to zero, the function is undefined.

Nothing can be concluded since f(1)\neq f(-1) and no such c in (-1,1) exists such that f'(c)=0

<u>THEOREM</u>

Rolle's theorem states that any real-valued differentiable function that attains equal values at two distinct points must have at least one stationary point somewhere between them—that is, a point where the first derivative is zero.

How do i find the vertex of y=-0.05x^2+1.25
NISA [10]
Y=-0.5x²+1.25

To find the vertex we need to write given equation in the vertex form.
y=a(x-h)²+k
(h,k) - coordinates of the vertex

y=-0.5x²+1.25 can be written as
y=-0.5(x-0)²+1.25
So, h=0, k=1.25
Vertex is (0, 1.25)
