Y = -5x + 1
x = 1 , y = -4
x = 2 , y = -9
x = 3 , y = -14
so the answers are
(1,-4)
(2,-9)
(3,-14)
Y=-a
x=b
a^2x-b^2y/ab=a+b
ax-by=2ab
20-3x=8
Subtract 20 from both side to get 12
Then 3x=12
Then divide 3 by both sides
Your answer is 4
Answer:
A= 16 B=28
Step-by-step explanation:
So the ration is 4:7, you have to find multiples that have that same ratio
Multiply both numbers by 4, this should get you
16:28
16 + 28 = 44
Therefore this is the correct answer
1: 2(3y+4)+9=
2 times 3y = 6y
2 times 4= 8 so
6y+8+9= 6y+17
