X = 3y - 4
x + y = 16
3y - 4 + y = 16
4y = 20
y = 5
x = 3(5) - 4
x = 11
Answer:
y = 4x -3
Step-by-step explanation:
The slope intercept form of an equation is
y = mx+b where m is the slope and b is the y ntercept
y = 4x -3
Answer: x + 3x = 11
Step-by-step explanation:
Two cities A and B
Both cities receive 11 inches of rainfall in total
Amount of Rainfall in inches received by city A = x
Amount of Rainfall in inches received by city B = 3x
Therefore given the details above, total rainfall is best expressed using the equation ;
Rainfall in city A + Rainfall in city B = 11 inches
x + 3x = 11
Answer:
It's been a while since I did one of these but I'm pretty sure it's 2.
Step-by-step explanation:
To determine a line's slope, subtract the second number in each coordinate.
-5 - 1 = -6
Then subtract the first numbers in each coordinate.
1 - 4 = -3
Finally taken the answer to the first equation and put it over the answer to the second equation.
-6/-3
There's your answer, of course you should simplify it. To do this divide -6 by -3.
-6/-3 = 2
Please take this with a grain of salt, it's been a while since I did this.
Answer:
m= -1 4/11
Step-by-step explanation: all you're doing is dividing the side with the variable (11/5m) by the side with the number by itself (-3)
