Which of the following statements is true

Answers

Answer 1

Answer:

The correct statement regarding the operations with polynomials is given as follows:

C. (10x³ + 2x² - 11) + 9x² + 2x - 2 = 10x³ + 11x² + 2x - 13.

What are like terms?

Like terms are terms that share these two features:

Same letters. (algebraic variables).

Same exponents.

If two terms are like terms, then they can be either added or subtracted, that is, we can use them to simplify a polynomial.

Hence the polynomial that is correctly simplified in this problem is given as follows:

(10x³ + 2x² - 11) + 9x² + 2x - 2 = 10x³ + 2x² + 9x² + 2x - 11 - 3 = 10x³ + 11x² + 2x - 13.

Meaning that option C is the correct option in the context of this problem.

Which transformations are needed to change the parent cosine function to y= 3cos(10(x-pi) )?

Answers

The parent cosine function can be transformed and translated. So, from the basic function cos(x) we can obtain function acos(bx+c). In our case, a=3- amplitude, b=10- the period change and c=-pi- the phase shift. So, the parent cosine function is mutiplied with 3 (which gives the amplitude of the function, 3*0.5=1.5). The period of the function is changed, and is 2pi/b=2pi/10=pi/5 and the cos(x) is phase shifted for c/b=-pi/10.

with a slope of -1.

Answers

Answer:

y= -1x +4

Step-by-step explanation:

So if you meant (-6,10) then I have solved it.

Writing this in y= mx+b form we already have M

y= -1x + b

So let’s substitute by putting in then y and x

10 = -1(-6) + b

10 -6= 6 -6+ b

4 = b
