Lelu [443]3 years ago
3 0

Answer:

m^3+m^2

Step-by-step explanation:

=> 2m^2-m^2(7-m)+6m^2

Collecting like terms and expanding the brackets

=> 2m^2+6m^2-7m^2+m^3

=> 8m^2-7m^2+m^3

=> m^2+m^3

=> m^3+m^2

The sum of the interior angles of a triangle is 180 degrees. Therefore, if we add up all of these angles, they will equal 180.

82 + 55 + x = 180

137 + x = 180

x = 43 degrees

Hope this helps!! :)

Graph the following non-linear system of equations and identify the two solutions. y=2x −7x+3y=3 What type of function is the eq
Ivanshal [37]

The solution to the given non linear system of equation is smallest x value , x = 0 , y = 1 , largest x value  x = 3 , y = 8 .

<h3>What is a Equation ?</h3>

An Equation is a mathematical statement which relates two algebraic expression with an equal sign in between.

The equations given in the question is

y = 2ˣ

This is an exponential function

-7x +3y = 3

This is a linear function

The equations have been plotted and the solution to the non linear system of equation has been determined

The point at which the graphs intersect is the solution to the system of non -linear equations.

(0,1) and (3,8)

x = 0 , y = 1 ; x = 3 , y = 8

The solution to the given non linear system of equation is smallest x value , x = 0 , y = 1 , largest x value  x = 3 , y = 8 .
