Answer:
(x,y)=-(1,1)
Step-by-step explanation:
-2x=8-6y (divide by -2)
=> x=-4+3y
-15x=21-6y (divide by -3 for simplicity)
=>5x=-7+2y
We know that x=-4+3y, insert this into expression "5x=-7+2y"
5(-4+3y)=-7+2y
-20+15y=-7+2y
15y-2y=20-7
13y=13
y=1
Since x=-4+3y we can find x by using y=-1
x=-4+3(1)
x=-1
Answer:
3
Step-by-step explanation:
To find the rate of change we: divide the change in y (output) by the change in x (input).
A = (-3 - 0) / (0 - 1) = -3 / -1 = 3
:)
Total portions are
5+4+3
12
One portion,
4860 / 12
405
So
5 : 4 : 3
5*405 : 4*405 : 3:405
2025 : 1620 : 1215
(-4,-5)(-6,3)
slope(m) = (3 - (-5) / (-6 - (-4)
slope(m) = (3 + 5) / (-6 + 4)
slope(m) = 8/-2 = -4
y = mx + b
slope(m) = -4
u can use either of ur points...I will use (-6,3)
3 = -4(-6) + b
3 = 24 + b
3 - 24 = b
- 21 = b <== here ya go
