Step-by-step explanation:

as explained in the other question : when applying an arithmetic operation on functions, you are applying it on the functional expressions.

(r*s)(x) = (x+3)*(2x²) = 2x³ + 6x²

(r-s)(x) = (x+3) - (2x²) = -2x² + x + 3

(r+s)(-1) = (-1 + 3) + (2×(-1)²) = 2 + 2×1 = 4

Stephanie spent 50% of x hours at her part-time job. What is x if 50% of x is about 46 hours? Explain how you estimated and whic
Liono4ka [1.6K]

Answer:

92 hrs

Step-by-step explanation:

Given 50% of x = 46 hrs

Then

50% /100% x X = 46

0.5 x X = 46

0.5x = 46

Divide both sides by 0.5

0.5x/0.5 = 46/0.5

x = 92

x is 92 hrs

Whic statement would best describe the graph of the function?
UNO [17]

First one.

Its a straight line with a slope of 6.

A line with a slope of 6 has a form of:

y=6x+0

So when x=1, y becomes 6\cdot1=6 and so on.

Hope this helps.

What is the sum or difference 4x^10 + 9x^10 A. 13x^10 B. 13x^20 C. -5x^10 D. 36x^10
olganol [36]

Answer:

The answer to your question is letter A

Step-by-step explanation:

Polynomial       4x¹⁰ + 9x¹⁰

To sum or subtract polynomials, just look for like terms and do the operations considering the rules of signs.

In this problem both terms are like terms, then we add the coefficients and write the variable without a change.

                         4x¹⁰ + 9x¹⁰  = 13x¹⁰
