ycow [4]

Things that make me skeptical: No evidence is provided, the company also claims that its washing machine produces 4000 joules of output for ever 3000 joules of input, and there is no possible way of creating a joule output larger than the input, unless your using coils to increase electricity, but that's not what washing machines have inside of their machinery. Washing machines don't have mini Tesla coils inside their machinery!

I hope this helps!

What is the equation of the linear function written in slope-intercept form?

-Dominant- [34]

Answer:

<h2>f(x) = -3x - 1</h2>

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$f(x)=mx+b$

<em>m</em><em> - slope</em>

<em>b</em><em> - y-intercept, (0, b)</em>

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

From the graph we have two points <em>A(-1, 2)</em> and <em>B(0, -1) → b = -1</em>.

Calculate the slope:

$m=\dfrac{-1-2}{0-(-1)}=\dfrac{-3}{1}=-3$

Finally:

$f(x)=-3x-1$

Determine if the statement is true or false. If a linear system has the same number of equations and variables, then it must hav

lutik1710 [3]

Answer:

False

Step-by-step explanation:

Consider the equations with the same number of equations and variables as shown below,

<u>Case 1</u>

$x_{1} + x_{2} = 0\\x_{1} + x_{2} = 1$

This equation has no solution because it is not possible to have two numbers that give a sum of 0 and 1 simultaneously.

<u>Case 2</u>

$x_{1} + x_{2} = 1\\2x_{1} + 2x_{2} = 2$

This equation has infinitely many possible solutions.

Therefore it is FALSE to say a linear system with the same number of equations and variables, must have a unique solution.
