Can a local maximum also be a point of inflection? Explain.
myrzilka [38]
<span>Inflection points are where the function changes concavity. Since concave up corresponds to a positive second derivative and concave down corresponds to a negative second derivative, then when the function changes from concave up to concave down (or vise versa) the second derivative must equal zero at that point. So the second derivative must equal zero to be an inflection point. But don't get excited yet. You have to make sure that the concavity actually changes at that point.</span>

use the elimination method to solve the system of equations choose the correct ordered pair 7x+4y=39 2y+4y=14
Anvisha [2.4K]

x = 5 \: and \: y = 1.

Step-by-step explanation:

7x + 4y = 39 \:  -  {eq}^{n} (1)

2x + 4y = 14  \: \:  -  {eq}^{n} (2)

Multiply Equation no (1) with 2 and Equation no (2) with 7.

14 x + 8y = 78.

14x + 28y = 98.

( - ) \: \:  \:  ( - ) \:  \:  \: ( - )

0x +  -20y =  - 20

- 20y =  - 20

y =  \frac{ - 20}{ - 20}

y = 1

Substitute the value of "y" in Equation no (1)

7x + 4y = 39.

7x + 4(1) = 39.

7x + 4 = 39.

7x = 39 - 4

7x = 35.

x =  \frac{35}{7}

x = 5.

URGENT PLEASE HELP!!!
Ira Lisetskai [31]

Answer:

1) -17x-9

Step-by-step explanation:

1)

(-2x^3+x-5)+(x^3-3x-4)

Combine like terms using P.E.M.D.A.S:

(-2x^3+x-5)+(x^3-3x-4)

(-9x-5)+(-8x-4)

Combine like terms:

(-2x^3+x-5)+(x^3-3x-4)

(-9x-5)+(-8x-4)

-17x-9

I hope this helps a bit!☺
