Answer:

A, D, E

Step-by-step explanation:

My favorite way to solve systems of nonlinear equations is to use a graphing calculator. The attached picture shows solutions to be near ...

x ≈ -1.18 . . . . choice A

x ≈ 2.26 . . . . choice D

x ≈ 3.28 . . . . choice E

_____

Other methods of solution might be to use a table or spreadsheet to show function values of each of the functions, or trying the offered values in the equations to see which ones are close.

1/2e=1/4 how do i solve that

Vladimir79 [104]

Answer =

E = 1/2 = 0.500
__________________________________________________

Now you need to rearrange the problem ( common sense :) :

1/2 * e - (1/4 ) = 0 | Now we need to Simplify 1/4 : 1/2 * e - 1/4 = 0
__________________________________________________

Now we need to simplify 1/2 : 1/2 * e - 1/4 = 0
__________________________________________________

What are there denominators??? = 2 and 4 ,,,,,, DUH . LOL
The lease common multiple is 4.

Now divide 1/2 by e which is 1/2 = 0.500

i hope this helps you a lot

Solve the system of equations given below.

eduard

Answer:

The system of this equation is ( -1, 10) which is Option A.

Step-by-step explanation:

Solve for y in the first equation.

$y = - 5x + 5 \\ - 2y = - x - 21$

Replace all occurrences of yy with -5x+5 in each equation.

$10x - 10 = - x - 21 \\ y = - 5x + 5$

Solve for x in the first equation.

$x = - 1 \\ y = - 5x + 5$

Replace all occurrences of x with -1 in each equation.

$y = 10 \\ x = - 1$

The solution to the system is the complete set of ordered pairs that are valid solutions.

(−1, 10)

Hence, the system of this equation is (-1, 10). 

Option A.

How do i solve n squared - 62

snow_lady [41]

The rule for this one is called the difference of squares
A^2 - b ^2 = (a+b)(a-b)

Using this rule
N^2 - 62 = (n+ sqrt(62)) (n - sqrt(62))

The solution for this one is to make the statement = 0
0 = (n+ sqrt(62)) (n - sqrt(62))

N can either be +- sqrt(62)
