Answer: x=-2
Y= -20
Step-by-step explanation
You replace the y in the second equation with 10x. This is because it says 10x=y
2x+10x=12x so you put that
12x=-24
To get x by its self you divide by 12.
-24 divided by 12 is -2.
Now you plug in -2 to either equation as y. I chose the first one because it's easier.
10(-2)=y
-20=y
Answer:
y= 3x + 8
Step-by-step explanation:
y = mx + b
m = 3 inches of water added each day
x = 8 inches of water at start
Answer:
Step-by-step explanation:
(-4,-23) , (-2,-11)
slope = (-11 - (-23) / (-2 - (-4) = (-11 +23) / (-2 + 4) = 12/2 = 6
y = mx + b
slope(m) = 6
(-4,-23)...x = -4 and y = -23
now we sub and find b, the y int
-23 = 6(-4) + b
-23 = -24 + b
-23 + 24 = b
1 = b
so ur equation is : y = 6x + 1....with ur slope being 6 and ur y int being 1 or (0,1)
** just so you know, instead of working out the y= mx + b and finding ur y int, u could have just looked at ur points...ur y int is when x = 0...and u have a point (0,1)....meaning ur x is 0....making 1 ur y int.
Their can be 6 arrangements of (2 men to
3 women, and opposite 5 men to 0 women and opposite, 4 men and 1 woman and opposite. so therefore their are 6 arrangements
