Answer:

23

Step-by-step explanation:

In this question, we want to evaluate the expression "9z-4" for z=3.

This means, we want to calculate the result when we substitute the z in this expression for 3.

So we have: 9(3)-4, which is equal to 23.

Let me know if this helps!

Urgent!

Answer:

The polynomial will be P(x) = - 5 (x + 2)²(x - 3)

Step-by-step explanation:

The degree of the polynomial P(x) is 3 and it has zeros at x = - 2 with multiplicity 2 and at x = 3 with multiplicity 1.

Therefore, (x + 2)² and (x - 3) are the factors of the equation.

Let the polynomial is

P(x) = a(x + 2)²(x - 3) ........... (1)

Now, the polynomial passes through the point (2,80).

So, from equation (1) we gat,

80 = a(4)²(-1)

⇒ a = - 5

Therefore, the polynomial will be P(x) = - 5 (x + 2)²(x - 3) (Answer)

I have this math problem and it is: an equation in function from that reflects f(x)=3x over the line y=0.
Gnoma [55]

Answer:

g(x) = -3x

Step-by-step explanation:

Given

f(x) = 3x

Required

Reflect over y = 0

This means that we reflect over the x-axis

And the rule of reflection is:

(x,y) \to (x,-y)

Hence:

f(x) = 3x

Will become:

g(x) = -f(x)

So, we have:

g(x) = -3x
