Answer:

Step-by-step explanation:

1)  First graph is correct! Because clearly, the roots are visible, and it's a 3rd degree polynomial, so it can't be bottom twos, cuz they're parabolas.

2) Roots are at -6, -2 and 3. (If you need further assistance on this, let me know!) Hence, It is the last graph!

3) Roots are at -4, -2 and 2, (Again, if you need assistance, let me know!)

Hence, it is the first one!

Hope this cleared things up for you!

Answer:

1) The degree of the polynomial function f(x) is 3, because it has three roots when f(x) = 0. Remember that the degree of a polynomial is dictated by the number of roots it has. (first graph)

2) The graph that represents g(x)=x^{3}+5x^{2}  -12x-36 is attached. There you can observe that the roots of this functoin are x=-6, x=-2 and x=3. The right choice is the graph placed at the bottom-right side.

3) The graph of the function f(x)=x^{3}+4x^{2}  -4x-16 is attached. Notice that its roots are x=-4, x=-2 and x=2. Therefore, the right choice is the graph placed at the top-left side.

-10(x + 21) = -15x + 18<br> What value of x makes the equation true?
schepotkina [342]
Answer:

x = 45.6

Explanation:

-10(x + 21) = -15x + 18

-10x - 210 = -15x + 18

-210 = -5x + 18

-228 = -5x

x = 45.6
