Answer:
f(x) = 5x - 30
Yes it is a function
Step-by-step explanation:
Because when you input 0 you get -30 we know it starts at 0 or (0,-30). This gives us b in the equation y = mx + b.
We know that for every 4 cars washed it increases by 20. So 20/4 is 5. This tells us m = 5.
Plug it all in and you get y = 5x - 30 or f(x) = 5x - 30
Answer:
0.75
Step-by-step explanation:
We do y/x to find out the Unit Rate.
So 1.2/1.6 = 0.75
Our equation would be 20+4n=A
20 represents the cost of the first sheet and then we add plus 4n which represents each additional sheets which leads out to A, our average cost per sheet.
Answer:
n² + 3n +1
Step-by-step explanation:
n(n+1) + 2n + 1
<h3>i) distribute n into the parantheses</h3>
= (n×n) + (n×1) + 2n + 1
= n² + n + 2n + 1
<h3>ii) collect like terms</h3>
= n² + 3n +1
