Answer:
y=-2x+4
Step-by-step explanation:
2x+y-1=0
2x+y=0+1
2x+y=1
y=1-2x
y=-2x+1
y=mx+b where m=slope and b=y-intercept
parallel means same slope,
so the slope would still be -2.
--------------
y-y1=m(x-x1)
y-2=-2(x-1)
y=-2x+2+2
y=-2x+4
Answer:
51.544 L in our tank
Step-by-step explanation:
We have a 13.6 gallon tank
Our conversion factor is 3.79 L = 1 gallon. We want liters on top since that is where we want to end up
3.79 L /1 gallon is what we want to use
13.6 * 3.79L/1 gallon = 51.544 L in our tank
7x+5y=-24 (1)
4x+y=42 (2)
multiply equation (2) by 5 to get
20x+5y=210 (3)
then calculate (3)-(2) which gives you
13x=234 hence x=18
then substitute for x in either equation to get y=-30
Answer:
n = 9.2
Step-by-step explanation:
Isolate the variable by dividing each side by the numbers that do not contain the variable
