Answer:

{ \rm{y = x + 4 -  -  - (a)}} \\ { \rm{y = 3x - 4 -  -  - (b)}}

equate equation a and equation b:

{ \rm{(a) = (b)}} \\ { \rm{x + 4 = 3x - 4}} \\ \\  { \rm{3x - x = 4 + 4}} \\  \\ { \rm{2x = 8}} \\  \\ { \boxed{ \rm{x = 4}}}

• find the value of y:

{ \rm{from \: (a) : }} \\  \\ { \rm{y = x + 4}} \\  \\ { \rm{y = 4 + 4}} \\  \\ { \boxed{ \rm{y = 8}}}

Solve the equation for x by graphing -2x + 3 = -3(-x) - 2
adoni [48]

Answer:

  x = 1

Step-by-step explanation:

There are a couple of ways to solve this. One is to graph the left side of the equation, graph the right side of the equation, and look for the point where those graphs intersect. It is at x = 1. The first attached graph shows this solution.

__

Another method for solving such an equation is to subtract one side from the other and look for the value of x that makes the resulting expression zero.

  (-2x +3) -(-3(-x) -2) = 0

A graphing calculator doesn't need to have this simplified. If it is simplified, it becomes ...

  -5x +5 = 0

So, the graphed line is y = -5x+5. Its x-intercept is x=1, the solution of the original equation. The graph of this is shown in the second attachment.

2x+4y=16 what is the slope intercept form
Eva8 [605]
Since slope intercept is y=mx+b, you first want to get rid of the 2x by subtracting it from both sides. after, you should end up with 4y=16-2x or 4y=-2x+16, they both are the same, but some teachers might prefer the slope first. after that, you want to get the y alone, so you divide everything by 4. you should end up with the slope intercept form being y=-2/4x+4, simplified to y=-1/2x+4.

Please do 81 cookies and distributed 44
AveGali [126]
I’m not quite sure what the question is, but 81 cookies distributed among 44 people would mean that each person gets 0.02 cookies each.
