Answer:
2.41 * n = y
Step-by-step explanation:
From the table, we can notice that the value;
y/n is a constant for each of the rows
this represents the individual costs of each of the books
So, we have it that;
7.23/3 = 4.82/2 = 9.64/4 = $2.41
So, the books have a unit cost of $2.41
Hence, by multiplying the number of books n by 2.41 we can get the cost y
So mathematically, we have the relation as;
2.41 * n = y

Step-by-step explanation:
Answer:
<h2>f(x) = 3x + 4</h2>
Step-by-step explanation:
f(x + 1) = 3x - 7
f(x) = f(x + 1 - 1) = 3(x - 1) + 7 = 3x - 3 + 7 = 3x + 4
Check
f(x) = 3x + 4
f(x + 1) = 3(x + 1) + 4 = 3x + 3 + 4 = 3x + 7 CORRECT
