A.Determine whether –(x3 + 5x + 1) is equivalent to x3 + 5x + 1. b.Determine whether (–x)3 + 5(–x) + 1 is equivalent to x3 + 5x + 1.
c. Determine whether –x3 + 5x + 1 is equivalent to –(x3 + 5x + 1).
d. Determine whether (–x)3 + 5(–x) + 1 is equivalent to –(x3 + 5x + 1)

A function is even if f(x) = f(-x) for all x.

f(-x) = -x³ + 5(-x) + 1
f(-x) = -x³ - 5x + 1

b.Determine whether (–x)3 + 5(–x) + 1 is equivalent to x3 + 5x + 1.

What is 2(x+5)<4+5x can i please get answer fast?
Korolek [52]

Answer:

x > 2

Step-by-step explanation:

2(x+5) = 2x + 10 -> 2x + 10 < 4+5x

Subtract 4 from each side.
2x +6 < 5x
Subtract 2x from each side
6 < 3x
2<x

So, x must be > 2

Ostrovityanka [42]
If Gina's age is x and Abigail is younger than Gina, Abigail's age will be represented by x-1 given that their ages are consecutive integers.

Translating the fact that the the difference of the square of Gina's age and eight times Abigail's age is 17, we will have the following equation:

x^{2} -8(x-1)=17

We can use the equation above to find Gina's age.

Enter the appropriate value to answer the question or solve the problem.
Licemer1 [7]

Answer:

slope 2.500

x intercept 1.80000

m intercept 4.50000

Step-by-step explanation:

<u>step 1:</u>

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                     5*(x+4)-(-2*(-4-m)+3)=0 

<u>step</u><u> </u><u>2</u><u>:</u>

   -4 - m  =   -1 • (m + 4) 

(5•(x+4))-((0--2•(m+4))+3) = 0

<em>step</em><em> </em><em>3</em><em>:</em>

5 • (x + 4) - (2m + 11) = 0

<u>step</u><u> </u><u>4</u><u>:</u>

5x - 2m + 9 = 0

<u>step</u><u> </u><u>5</u><u>:</u>

 Solve   5x-2m+9  = 0

Nitella [24]

Answer:

The exact solution for this equation would be (2.222, -11.889)

Step-by-step explanation:

Since it told us to use a graphing calculator, I went on to desmos graphing calculator, typed in the equation, then I found out where the two line intersect, and then that was the answer.
