3 + 0.75x = 5.25 - 0.25x
0.75x = 2.25 - 0.25x
x = 2.25
3 + 0.75(2.25) = 5.25 - 0.25(2.25)
3 + 1.6875 = 5.25 - 0.5625
4.6875 = 4.6875
They are equal
Answer:
y = - x - 6
Step-by-step explanation:
y = mx + b
m = - 1
y = - x + b
(- 4, - 2)
- 2 = - (-4) + b
-2 = 4 + b
b = - 6
y = - x - 6
The key words you should notice when looking at this word problem are “less than.” This means that the order is flipped, so “3 less than k” means “k minus 3.”
The expression for the ratio is k-3:k+3
