It is 7 .....................................................
Answer:
1. Linear
2. Not Linear
3. Linear
4. Linear
Step-by-step explanation:
<u>Function 1</u>
Linear, follow a sequence of 4, 3
<u>Function 2</u>
Not Linear, does not follow a sequence
<u>Function 3</u>
Linear, follow a sequence of 1, 0
<u>Function 4</u>
Linear, follow a sequence of 3, -1
Since both 2 and 5 are prime numbers, there are no multiples for the fraction 2/5.
The second answer.
You have the first prize, x.
Then you have the second prize, which is x - 50.
Then you have the third prize, which is x - 50 -50, or x - 100.
So the total money is:
x + (x-50) + (x-100).
According to the vertex and the directrix of the given parabola, the equation is:

<h3>What is the equation of a parabola given it’s vertex?</h3>
The equation of a quadratic function, of vertex (h,k), is given by:

In which a is the leading coefficient.
The directrix is at y = k + 4a.
In this problem, the vertex is (1,4), hence:

The directrix is at y = 7, hence:


Hence, the equation is:
