For n = 2d squared - 5 when d = -2nwhat does n equal

The value of n

n = 0.86

n = -0.73

Step-by-step explanation:

Given:

The given equation is

We need to find the value of n when d = -2n.

Solution:

Rewrite the given equation as

Substitute d = -2n in above equation.

Now, we first find the root of the above equation.

Use quadratic formula with .

Put a, b and c value in above equation.

For positive sign

n = 0.86

For negative sign

n = -0.73

Therefore the value of n = 0.86 or n = -0.73

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;

answer: y = -2.5x - 15

              (-6,0)
