2x - 3 = 2x - 1

- this makes no sense so there is no solution to this equation.

2x - 3 = -(2x - 1)

2x - 3 = -2x + 1

4x = 4

x = 1

Checking this solution:-

2(1) - 3 = -1

-(2(1) - 1) = -1( 1) = -1

So this solution is valid.

Answer:

B. CSCX= sinx / 1

D. tanx= sin x / COS x

Step-by-step explanation:

A. sec x= 1/cos(x)

CSC X / 1 = sin(x)

B. CSCX

sinx / 1 = csc(x)

C. tanx= sin(x) / cos(x)

secx = 1 / cos(x)

Use Newton's method with initial approximation x1 = −2 to find x2, the second approximation to the root of the equation x3 + x +

Answer:

The value of $x_2=-1.6923$ .

Step-by-step explanation:

Consider the provided information.

The provided formula is $f(x)=x^3+x+6$

Substitute $x_1=-2$ in above equation.

$f(x_1)=(-2)^3+(-2)+6$

$f(x_1)=-8-2+6$

$f(x_1)=-4$

Differentiate the provided function and calculate the value of $f'(x_1)$

$f'(x)=3x^2+1$

$f'(x)=3(-2)^2+1$

$f'(x)=13$

The Newton iteration formula: $x_2=x_1-\frac{f(x_1)}{f'(x_1)}$

Substitute the respective values in the above formula.

$x_2=-2-\frac{(-4)}{13}$

$x_2=-2+0.3077$

$x_2=-1.6923$

Hence, the value of $x_2=-1.6923$ .

Each day that a library book is kept past its due date, a $0.30 fee is charged at midnight. Which ordered pair is a viable solut

castortr0y [4]

$0.30x=y should be the answer because there is a 30cent fee for every day and x represents how many days it's kept therefore you would add 30 cents for every day it's kept so it's valid to say $0.30x=y becaue the 30 cents times the total of days it's kept = y (the toatl)
