How do you do systems of two equations? Problem: y=-3x+4, y=3x-2

1 answer:

8 0

I assume you are trying to solve for each variable. if thats the case you want to use one equation to solve for y and then plug the y value into the next variable
Problem: y =-3x=4 so -3x+4=3x-2
x=1
plug x value into one of the equations
y=3(1)-2
y=1

The cost of 5 pounds of boudin is $26.What is the constant of proportionality that relates the cost in dollars,y, to the number

Ymorist [56]

Given :

The cost of 5 pounds of boudin is $26.

To Find :

The constant of proportionality that relates the cost in dollars y, to the number of pounds of boudin x .

Solution :

Price per boudin in terms of x and y is :

$P=\dfrac{y}{x}$

Price per boudin by given data :

$P=\dfrac{26}{5}$

So,

$\dfrac{y}{x}=\dfrac{26}{5}\\\\y = \dfrac{26}{5}x$

Therefore, the constant of proportionality is $\dfrac{26}{5}$ .

Hence, this is the required solution.

I have to rewrite an equation so that y is a function of x. I think I'm solving for Y, because on my examples it has "y=". How d

vivado [14]

You do whatever you need to do to one side of the equation in order to have
only ' y ' left on that side, AND every time you do something to that side of
the equation, do exactly the same thing to the other side.

Here are three examples, out of the 9 answers you want handed to you:

#16: 3x + 5y = 7

Subtract 3x from each side: 5y = -3x + 7

Divide each side by 5 : y = -3/5 x + 7/5

======================================

#17:  13 = 12x - 2y

Add 2y to each side: 2y + 13 = 12x

Subtract 13 from each side: 2y = 12x - 13

Divide each side by 2 :  y = 6x - 13/2

======================================

#22: 1/4 y + 3 = -5x

Subtract 3 from each side: 1/4 y = -5x + 3

Multiply each side by 4 : y = -20x + 12
