Answer: x = - 3

Step-by-step explanation:

The equation is in a standard form of equation as;

y = ax^2 + bx + c, and therefore, the axis of symmetry is given by the formula,

X = - b / 2a.

Therefore using that in the question, a = 1 and b= 6

Therefore, the axis of symmetry is:

x = - (6) / 2(1) which gives

x = - 3

BaLLatris [955]

Answer:

x > 9/10 is the answer to the equation.

Step-by-step explanation:

3x -2(x -1) > 11-9x

3x -2x +2 > 11-9x

x+2> 11-9x

x+9x > 11-2

10x > 9

x > 9/10

Complete the equation, by supplying the missing exponent.<br> m•n2•m3= m 11n2

MaRussiya [10]

Given:

Consider the given equation is:

$m^?\cdot n^2\cdot m^3=m^{11}\cdot n^2$

To find:

The missing exponent.

Solution:

Let x be the missing exponent. Then the given equation can be written as

$m^x\cdot n^2\cdot m^3=m^{11}\cdot n^2$

It can be rewritten as:

$(m^x\cdot m^3)\cdot n^2=m^{11}\cdot n^2$

$m^{x+3}\cdot n^2=m^{11}\cdot n^2$ $[\because a^ma^n=a^{m+n}]$

On comparing the coefficient of m, we get

$x+3=11$

$x=11-3$

$x=8$

Therefore, the value of the missing exponent is 8. So, the complete equation is $m^8\cdot n^2\cdot m^3=m^{11}\cdot n^2$ .
