Answer:
4 pepperoni pizzas
Step-by-step explanation:
<span>4x+2(3x-9)=42
first we want to distribute the 2 using the distributive property
4x+6x-18=42
Then we simplify
</span><span>10x-18=42
we add 18 to both sides
10x=60
divide both side by 10
x=6</span>
As x increases, y increases. So this data has a positive association. The association looks to be strong, as the values all follow the trend pretty closely.
