What would the slope of a line be if it were parallel to the line: y = 1 / 3x - 5 ?

1 answer:

5 0

Answer:

Parallel lines have the same slope, so the slope would be 1/3. It would need a different y intercept though or it would be the same line.

Given the function f(x)= 5(x+4) -6 solve for the inverse function when x = 9

NARA [144]

Answer: $y^{-1}=-1$

Step-by-step explanation:

Rewrite the function as following:

$y=5(x+4)-6$

Now, you must solve for x as you can see below:

$y=5x+20-6\\y=5x+14\\y-14=5x\\x=\frac{y-14}{5}$

Rewrite it as following:

$y=\frac{x-14}{5}$

Now substitute x=9 into the function above, then, you obtain:

$y=\frac{9-14}{5}$

$y^{-1}=-1$

A baby was born 3/4 of a month early. At birth its weight was 7/8 kilograms, which is 9/10 kilograms less than the average weigh

BlackZzzverrR [31]

Answer:

The average weight of a newborn otter is 1.775 kg.

Step-by-step explanation:

We are given the following in the question:

Weight of newborn otter =

$\dfrac{7}{8}\text{ kg}$

Let x lg be the average weight of a newborn otter.

Thus, we are given the relation:

$\dfrac{7}{8} = x - \dfrac{9}{10}\\\\x = \dfrac{7}{8} + \dfrac{9}{10}\\\\x = \dfrac{35+36}{40} = \dfrac{71}{40}\\\\x = 1.775\text{ kg}$

Thus, the average weight of a newborn otter is 1.775 kg.
