You'll do just fine, just make sure to study and have some sleep, okay?
2.)
0 = 6x + 3y +9
-3y = 6x + 3y - 3y +9

By isolating y we now have the equation in slope intercept form:

Where m = slope and b = y- intercept. Therefore, the slope is -2 and the y - intercept is -3.
4.)
Similarly, #4 is already in slope intercept form so we can solve it by inspection. So for #4 the slope is -1 and the y - intercept is 2.
Use y2-y1/x2-x1
So 0-5/3-2
-5/1= m= -5
Then plug it into y=MX+B
0= -5(3)+b
0= -15+b
b=15
y=-5x+15
So I hope this helps but I'm not sure how to plug it into that's equation. The rest of my work is rigt
To know how many liters of water Bao use per liter of flour we have to divide the liters or flour so:

So Bao uses 0.33 or 1/3 of water per liter or flour
and to know hoy manu liters of flour Bao use per liter of water we have to made the oposite division so:

She use 3 liters of flour per liter of water
Answer: 1,000 cm^3
Step-by-step explanation:
Volume of cube= bhw
All sides of a cube are equivalent so 10^3= 1000
