Then will solve the rest, 20 - 18

20 - 18 = 2, therefore leaving us with the answer of 2

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 .

algol [13]
We can take the equation,
0.19x + 21.58 = 25
0.19x = 25 - 21.58
0.19x = 3.42
x = 3.42/0.19
x = 18

The answer is 18 minutes!

Greatest common factor <br> 3m-12n
Zigmanuir [339]

Answer:

3

Step-by-step explanation:

To find the Greatest common factor (GCF) of 3m-12n we find the highest letters and/or numbers that is a factor of both :

3m-12n

Both have a common factor of 3 :

\frac{3m-12n}{3} = m-4n

m-4n cannot be simplified anymore so the gcf of 3m-12n is 3.

Hope this helped and have a good day
