Answer:

When x = -2, g(x) = -6

When x = 0, g(x) = 0

When x = 5, g(x) = 15

Step-by-step explanation:

We have a function and are asked to evaluate and solve when we have three different values for x.

To solve, all we need to do is substitute the numbers with the corresponding value.

3(-2)

-6

3(0)

3(5)

Simplify negative 2 and 1 over 6 – negative 7 and 1 over 3. negative 5 and 1 over 6 negative 9 and 3 over 6 9 and 3 over 6 5 and

luda_lava [24]

Answer:

5 and 1 over 6

Step-by-step explanation:

Simplifying the given:

Negative 2 and 1 over 6 – negative 7 and 1 over 3 ⇒ translated as:

- 2 1/6 - (-7 1/3) = ⇒ cancelling negatives and changing mixed fractions to improper fractions

- 13/6 + 22/3 = ⇒ bringing to same denominator

- 13/6 + 44/6 = ⇒ calculating the numerator
31/6 = ⇒ making mixed fraction
5 1/6 ⇒ answer

Correct choice is the last one: 5 and 1 over 6

Hence, write as single frachon in its lowest terms. 2/y-1 - 4/y^2-1

sleet_krkn [62]

Answer:

$\frac{2}{y+1}$

Step-by-step explanation:

Factorise the denominator of the second fraction

y² - 1 = (y - 1)(y + 1) ← difference of squares

To obtain a common denominator

multiply numerator/ denominator of first fraction by (y + 1)

= $\frac{2(y+1)}{(y-1)(y+1)}$ - $\frac{4}{(y-1)(y+1)}$ ← subtract numerators leaving the common denominator

= $\frac{2y+2-4}{(y-1)(y+1)}$

= $\frac{2y-2}{(y-1)(y+1)}$

= $\frac{2(y-1)}{(y-1)(y+1)}$ ← cancel common factor (y - 1) on numerator/denominator

= $\frac{2}{y+1}$
