I need to solve this system of equations, how do I do that?<br> 3x-4y=20<br> y=3/4x-5
Paha777 [63]

Answer:

Is is Infinitely many solutions so 0=0

<em><u>Step-by-step explanation:</u></em>

<h3>First we have to rearrange/simplify the equations:</h3>

Equation 1: 4y - 3x = -20

Equation (2):  y - 3x/4  = -5

<h3>Then you remove the fractions by multiplication: </h3>

Multiply equation (2) by 4

<h3>The Equations now look like this: </h3>

Equation 1: 4y - 3x = -20

Equation (2): 4y - 3x = -20

<h3>Solve for y on Equation (2):</h3>

y = <u><em>3x/4 - 5</em></u>

<h3>Then plug in this for the y in Equation 1 and then solve:</h3>

4•(<u><em>3x/4-5</em></u>) - 3x = -20

Therefore the answer leads to:

Infinitely many solutions, 0=0

Hope this helped :')

1.) Is f(x)=2x^3 + 2x and odd function
Amiraneli [1.4K]

Answer:

yes, no, no

Step-by-step explanation:

For odd functions : −f(x) = f(−x) for all x

For even functions :f(x) = f(−x) for all x

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

f(-x) = -2x^3-2x

yes

2 ) f(-x) = 5x^3 -4 ≠ f(x)

no

3  )  f(-x) = -4x -4   ≠ f(x)

no
