The equation 3x2 = 6x - 9 has two real solutions<br> True<br> False

dedylja [7]

Answer: FALSE

Step-by-step explanation:

The first step is to rewrite the equation in the form $ax^2+bx+c=0$ , then:

$3x^2 = 6x - 9\\3x^2-6x +9=0$

Now, we need to calculate the Discriminant with this formula:

$D=b^2-4ac$

We can identify in the given equation that:

$a=3\\b=-6\\c=9$

Then, we only need to substitute these values into the formula:

$D=(-6)^2-4(3)(9)$

$D=-72$

Since $D$ then the equation has no real solutions.

What is the inverse of the function f(x) = 4x + 8?

Vera_Pavlovna [14]

Answer:

h(x) = (1/4)x-2

Step-by-step explanation:

You can substitude y for f(x) for convenience.

y = 4x + 8.

Inverse of functions swap positions of x and y

Therefore, you have equation x = 4y + 8

Now you solve for y again:

x/4 - 2 = y
