Answer:

The root of 16 is 4 and the root of 9 is 3.

Step-by-step explanation:

For the first instance, 16+9 is 25 and the root of that is 5. But for the second one, we have to first find the roots. So 4+3 which equals 7. These are obviously not equal. Does this make sense? Hope that helps.

Answer:

<u>Step 1:  Justify</u>

Solve the first one

<u />\sqrt{16+9} → \sqrt{25}

\sqrt{25} → 5

Solve the second one

\sqrt{16} + \sqrt{9} → \sqrt{4^2} + \sqrt{3^2}

\sqrt{4^2} + \sqrt{3^2} → 4+3

4+3 → 7

So...

5\neq 7

Mary is analyzing a quadratic function f(x) and a linear function g(x). Will they intersect? Which coordinates if they do? Negat
Umnica [9.8K]

Answer:

The graphs of the two function will not intersect.

Step-by-step explanation:

We are given a quadratic function f(x).

Also g(x) is given by a set of values as:

 x            g(x)

 1              -1

  2             0

  3              1

As g(x) is a linear function hence we find out the equation of g(x) by the slope intercept form of a line: y=mx+c

let g(x)=y

when x=1 ,   g(x)=-1

-1=m+c----(1)

when x=2   , g(x)=0

0=2m+c------(2)

Hence, on solving (1) and (2) by method of elimination we get:

m=1 and c=-2

Hence, the equation of g(x) is:

g(x)=x-2

So clearly from the graph we could see that the graph of the two functions will never intersect.

Urgent. Factor the trinomial by grouping. Please show work. 14x^2y+9xy^2+y^3. If prime, show how you got prime answer.
ch4aika [34]

Answer:

y x (2x +y) x (7x +y)

Step-by-step explanation:

14x^2y + 9xy^2 +y^3

(Factor the expression)

y x (14x^2 +9xy +y^2)

(Rewrite the expression)

y x (14x^2 + 7xy +2xy +y^2)

(Factor the expression)

y x (7x x(2x +y) + y x (2x +y) )

(Factor the expression)

y x (2x +y) x (7x +y)

F(x)=8_-4x-x^3. g(x)=x^2+7x-9. Find f(x)+g(x)
11111nata11111 [884]

(8 - 4x -  {x}^{3} ) + ( {x}^{2}  + 7x - 9) \\  =  -  {x}^{3}  +  {x}^{2}  - 4x + 7x + 8 - 9 \\  =  -  {x}^{3}  +  {x}^{2}  + 3x - 1
(8x - 4x -  {x}^{3} ) + ( {x}^{2}  + 7x - 9) \\  -  {x}^{3}  +  {x}^{2}  + 8x - 4x + 7x - 9 \\  -  {x}^{3}  +  {x}^{2}  + 11x - 9
The answer is either B, and you forgot to put in the ^2 in the answer choice, or C, and you forgot to put an x where there is a _ in the question.

Check the actual question (the one you recieved, not the one posted here) and see where the mistakes are. If f(x) = 8x - 4x - x^3, then your answer is C. However, if B is actually -x^3 + x^2 + 3x - 1, then the answer is B.
