First off, add 3 to both sides of the equation.
6n - 3 + 3 > -18 + 3
Then, your equation should look like this: 6n > -15
Next, divide both sides by 6.
6n/6 > -15/6
Your answer is n > -5/2

Your answer : n > -\frac{5}{2}


How I FOUND my answer ↓


Rearrange⇒ 6 × n- 3 - (-18) > 0 

Take out the like terms ⇒ 6n + 15 = 3 × (2n + 5)

Divide both sides by  3 and 2 

n + (\frac{5}{2} ) > 0

Then subtract both sides by -\frac{5}{2} ⇒ n -\frac{5}{2} 

Lastly, 6.000 x + 15.000 > 0

Let f(x)=x2−2x−4 . What is the average rate of change for the quadratic function from x=−1 to x = 4?
goblinko [34]

Answer:

The average rate of change for f(x) from x=−1 to x = 4 is, 1

Step-by-step explanation:

Average rate A(x) of change for a function f(x) over [a, b] is given by:

A(x) = \frac{f(b)-f(a)}{b-a}

As per the statement:

f(x) = x^2-2x-4

we have to find the average rate of change from x = -1 to x = 4

At x = -1

f(-1) = (-1)^2-2(-1)-4 = 1+2-4 = -1

and

at x = 4

f(4) = (4)^2-2(4)-4 = 16-8-4 = 4

Substitute these in [1] we have;

A(x) = \frac{f(4)-f(-1)}{4-(-1)}

⇒A(x) = \frac{4-(-1)}{4+1}

⇒A(x) = \frac{5}{5}

Simplify:

A(x) = 1

Therefore, the average rate of change for f(x) from x=−1 to x = 4 is, 1

Use the quadratic formula to solve the equation to the exact value or round to two decimal places.
lys-0071 [83]
First set everything to 0.
{x}^{2}  + x - 5
Giving you A= 1 , B= 1 and C= -5
Then input everything into the quadratic formula and either solve by hand or use a calculator.
Note exact values are found by hand, decimals are found using a calculator.
