What is the axis of symmetry of the function f(x) = -(x+9)(x-21)

LUCKY_DIMON [66]

Answer:

x = 6

Step-by-step explanation:

Take f(x) = -(x+9)(x-21) and multiply it out. We get:

f(x) = -[x^2 + 9x - 21x - 189], or

f(x) = -x^2 + 12x + 189

This is a quadratic equation. The coefficients are a = -1, b = 12 and c = 189.

The equation of the axis of symmetry is x = -b/(2a), which here equals:

x = -12 / [2*(-1)], or x = 6.

Yusuf earned a total of $180 from drying 12 identically-price pictures at a festival. Write an equation to describe the relation

Anarel [89]

Answer:

$E=15P$ is the required relationship.

Step-by-step explanation:

We have bee give that the Yusuf earned a total of $180 from drying 12 identically-price pictures at a festival.

That means if we count earning for one picture is: $\frac{180}{12}=15$

We need to find the relationship between P and E

Where, P is the price of the picture

And E is the earning.

$E=15P$

If we put different values of P we will get the earning for the number of pictures.
