Get x on one side then you can use substitution
So, change x+3y=3 to x= -3y+3
Then plug in x to other equation to find y
2(-3y +3)-3y=-12
-6y + 6 -3y = -12
-9y = -18
Divide both sides by negative nine to find y
y = 2
Then plug in to original equation to find x
x + 3(2) = 3
x + 6 = 3
x = -3
So, y = 2 and x = -3
Answer:
The slope is 4/3
Step-by-step explanation:
Answer:
is the system of equations representing the situation.
Step-by-step explanation:
Given:
Alexandra finds that she can give 3 haircuts and 2 hair dyes in 315 minutes. Giving 2 haircuts and 4 hair dyes takes 450 minutes.
Now, to find the system of equations representing the situation.
<u><em>Let the number of haircuts be </em></u><u><em /></u>
<u><em>Let the number of hair dyes be </em></u><u><em /></u>
So, Alexandra can give 3 haircuts and 2 hair dyes in:
Now, giving 2 haircuts and 4 hair dyes in:
Therefore,
is the system of equations representing the situation.
If 1 is 65 then:
2=180-65=115
3=65
4=115
5=115
6=65
7=115
8=65
The slope-intercept form for these coordinates is as follows: y= -2/5x+6.8
