(2, 1)
</span> <span>Which ordered pair is a solution of the inequality?
a.</span>
So let's add variables according to the ratio:
3n + 2n = <span>£80
5n = </span><span>£80
n = 16
3(16):2(16)
48:32
Tom gets </span>£48, and Jerry gets <span>£32</span>
Answer:
slope = - 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = P(- 4, 2) and (x₂, y₂ ) = Q(4, - 4)
m = 
= 
= -
