Answer:

y = x/3 - 2 or f(x) = x/3 - 2

Step-by-step explanation:

f(x) = y

y = 3x + 6

To solve for inverse change y to x and x to y and solve for y.

x = 3y + 6 //Subtract 6 on both side

x - 6 = 3y //Divide 3 on both side

x/3 - 6/3 = y //Simply

y = x/3 - 2

Write an expression that is equivalent to 3/5 (3y+15)<br> 3/5y +9, 3/5y+15, 9/5y+9, 9/5y + 15?

NISA [10]

Given the expression

$\frac{3}{5} (3y+15)$

The expression that is equivalent to the given expression is given by:

$\frac{3}{5} (3y+15)= \frac{9}{5} y+ \frac{3}{5} (15)= \frac{9}{5} y+9$

A ship leaves port at 1:00 P.M. and travels S35°E at the rate of 27 mi/hr. Another ship leaves the same port at 1:30 P.M. and tr

Len [333]

To solve this problem you must apply the proccedure shown below:

1. You must apply the Law of Cosines, as you can see in the figure attached. Then:

- The first ship travels at $27 mi/hr$ in for two hours. Therefore, the side $a$ is:

$a=(27 mi/hr)(2 hr)=54mi$

- The second ship travels at $18 mi/hr$ for $1.5 hours$ . Therefore, the side $b$ is:

$b=(18mi/hr)(1.5hr)=27mi$

- Now, you can calculate $c$ :

$c=\sqrt{54^{2}+27^{2}-2(54)(27)Cos(55)}=44 mi$

The answer is: $44 miles$

Dragon drop each expression two correctly classify it as having a positive or negative product

ioda

Step-by-step explanation:

We multiply it to find the product

positive times positive = positive

positive times negative = negative

negative times positive = negative

negative times negative = positive

$(-\frac{1}{3})(-\frac{1}{3})= \frac{1}{9}$

Negative and negative is positive , so product is positive

$(-\frac{1}{3})(\frac{1}{3})= -\frac{1}{9}$

Negative and positive is negative , so product is negative

$(\frac{1}{3})(-\frac{1}{3})= -\frac{1}{9}$

positive and negative is negative , so product is negative

$(\frac{1}{3})(\frac{1}{3})= \frac{1}{9}$

positive and positive is positive , so product is positive
