Answer:
The inverse of a given function
d)
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given that f(x) = 4x + 12
let y = 4 x + 12
4 x = y - 12
we know that y = f(x)
⇒ x = f⁻¹(y)
Put replace 'y' in 'x'
<u><em>Final answer</em></u><em>:-</em>
The inverse of a given function
The value of a is 9, the correct option is B.
Given
Hank’s teacher asked him to verify that the product (y−3)(y2+3y+9), is a difference of cubes.
<h3>Quadratic equation;</h3>The equation which has the highest degree is 2 is called quadratic equation;
Where a, b, and c are the constants.
The given polynomial is;
On multiplying the terms;
On comparing;
Hence, the value of a is 9.

Answer:
Step-by-step explanation:
We are given the following in the question:
Cost of one cupcake = $3.50
Cost of one fruit tart = $3
Total money Harry have = $50
Harry bought 8 cupcakes and fruit tarts.
We have to write the inequality giving relation between the total number of cupcakes and fruit tarts Harry can buy the amount of money he has.
Total cost of purchase =
= Total cost of cupcakes + Total cost of fruit tarts
Now, this total cost of Harry's purchase should be less than than equal to $50.
is the required linear inequality.
