H(x) = 3х – 4<br> What is h(6)?

xeze [42]

Answer:

Step-by-step explanation:

h(6) means what is the value of h(x) when x is 6.

The value given for h(x) is 3x-4.

So we need to evaluate the expression 3x-4 for x=6.

Replace x with 6: 3(6)-4

Now perform order of operations.

3(6)-4

18-4

A cubic equation has factors of (x + 2)(x^2 + 7x + 10). Determine ALL of the real roots. Which one is a double root?

Gnesinka [82]

Answer:

x = -2, -5 where -2 is a double root

Step-by-step explanation:

The real roots are the solutions to the cubic equation. You find them by setting each factor equal to 0 and solving for x.

$x+2 = 0 \\x= -2$

$x^2 + 7x +10 = 0\\(x+2)(x+5) = 0\\x=-2, -5$

Since -2 appears twice, it is a double root.
