Answer:

The answer is 5

Step-by-step explanation:

First you subtract 3 from both sides and get 10. Then you divide by 2 and you get 5.

Answer:

x = 8 (but I could be wrong)

Step-by-step explanation:

Add 3 to both sides of the equation

2x=13+3

add 13 and 3

2x=16

Then divide each of the terms by 2 and simplify

Divide 2x = 16 by 2

2x/2 = 16/2

Then cancel the common factor of 2

so 2x/2 (but crossed out) = 16/2

then divide x by 1 x=16/2

then divide 16 by 2

And x=8

Given the graph of f ′(x), the derivative of f(x), which of the following statements are true about the graph of f(x)?

GarryVolchara [31]

$f'$ has a horizontal tangent line at $x=2$ , and it's clear from the plot that $f'$ is increasing to the left and descreasing to the right. This means $f''=0$ when $x=2$ , so there is an inflection point there and only statement II is true.

Statement III is not true because critical points only occur where $f'=0$ or (possibly) when $f'$ is undefined. Clearly $f'\neq0$ when $x=2$ .

The sum of the roots of 3x 2 + 11x - 4 = 0 is -11/3 -4/3 11/3 4/3

givi [52]

Answer:

The correct option is 1.

Step-by-step explanation:

If a quadratic equation is defined as

$ax^2+bx+c=0$ .... (1)

Then the sum of the roots is -b/a and the product of roots is c/a.

The given equation is

$3x^2+11x-4=0$ ... (2)

From (1) and (2) we get a=3, b=11 and c=-4.

The sum of roots is

$\frac{-b}{a}=-\frac{11}{3}$

The sum of roots is $-\frac{11}{3}$ .

Therefore the correct option is 1.
