Answer:

Step-by-step explanation:

13p⁵ + 6p - 12p² -(-9p - p² - 13p⁵) = 13p⁵ + 6p - 12p² + 9p + p² + 13p⁵

{Distribute (-1) to the second expression}

= 13p⁵ + 13p⁵ -12p² + p² + 6p + 9p

{Combine like terms}

= 26p⁵ - 11p² + 15p

2) Select the algebraic definition for the piecewise function graph.

Lady bird [3.3K]

Answer:

The answer is C - 2x + 8.

Step-by-step explanation:

In the first domain:

$0 \leqslant x < 2$

does not exist.

in the second domain:

$2 \leqslant x < 4$

The function is:

$f(x) = - 2x + 8$

Which decimal number is equal to 3/18 A.0.167 B.0.16 C.0.16 D.0.167

natita [175]

Answer:

0.167

Step-by-step explanation:

Note that 3/18 reduces to 1/6. 1/6 is a rational number whose decimal equivalent is repeating: 1/6 = 0.166666 ...

It appears that answer choices A and D are identical, as arer B and C. You might want to verify that you've copied down the answer correctly.

Answers A and D (identical) are the best choices here, due to less rounding off.

The graph attaches shows the function f(x) and the table represents the function g(x)

Fed [463]

Answer:

Statement D is true

Step-by-step explanation:

We should know the following:

x-intercept is the value of x when y = 0

y-intercept is the value of y when x = 0

As shown on the graph, we can deduce the following:

For f(x) : at y = 0 ⇒ x = 1 And at x = 0 ⇒ y = -1

So, for f(x) ⇒ x-intercept = 1 & y-intercept = -1 

For g(x) : at g(x) = 0 ⇒ x = -1 And at x = 0 ⇒ g(x) = 1

So, for g(x) ⇒ x-intercept = -1 & y-intercept = 1

Comparing the results with the given options:

A) the x-intercept of f(x) is equal to the x-intercept of g(x) (Wrong)

B) the y-intercept of f(x) is equal to the y-intercept of g(x) (Wrong)

C) the y-intercept of f(x) Is greater than the y-intercept of g(x) (Wrong)

D) the x-intercept of f(x) is greater than the x-intercept of g(x) (true)
