Answer:

-20 + 30x

Step-by-step explanation:

-10(1) = -10

-10(-3x) = 30x

new equation

-10 + 30x -10

-10 + -10 = -20

-20 + 30x

A farmhouse shelters 11 animals. Some are goats and some are ducks. Altogether there are 34 legs. How many of each animal are th

andriy [413]

We are given that there are 11 animals with a total of 34 legs.

Let G = number of Goats, and D = number of Ducks

then G + D = 11; solving for G, we get G = 11 - D

then, 4G + 2D = 34

substituting the value for G, we get 4(11 - D) + 2D = 34

expanding, we get 44 - 4D + 2D = 34

solving, we get D = 5. Therefore, G = 6

Proof: (5 x 2) + (6 x 4) = 34

Answer:

x ∈ (-∞ , -2) ∪ (1, 3)

Step-by-step explanation:

The expression is already factored. Note that for the polynomial that appears in the numerator $(x-3)(x + 2)$ there are 2 roots:

$x = 3\\x = -2$

For the polynomial that appears in the denominator there is 1 root:

$x = 1$

Note that $x = 1$ does not belong to the domain of f(x) because it zeroes the denominator of the function and the division between zero is not defined.

With these three roots we do the study of signs to find out when $f(x)$
