If there are no repeating x values and an x value only goes to one y value, then yes, it is a function.

Hello! Please help thanks

Answer:

A. $\frac{5}{13}$

Step-by-step explanation:

Hi there!

We are given right triangle PQR, with PR=5, RQ=12, and PQ=13

We want to find the value of sin(Q)

Let's first recall that sine is $\frac{opposite}{hypotenuse}$

In reference to angle Q, PR is the opposite side, RQ is the adjacent side, and PQ is the hypotenuse

So that means that sin(Q) would be $\frac{PR}{PQ}$

Substituting the values of PR and PQ gives sin(Q) as $\frac{5}{13}$ , which is A

Hope this helps!

4x+3y=20 2x+y=7 How do I solve this? I forgot how to do it :/ also no answer choice

Crank

So for this, I will be using the substitution method. Firstly, subtract both sides in the second equation by 2x: $4x+3y=20\\ y=7-2x$

Next, substitute y in the first equation with 7-2x, then solve for x from there:

$4x+3(7-2x)=20\\ 4x+21-6x=20\\ -2x+21=20\\ -2x=-1\\ x=\frac{1}{2}$

Now that we got x, substitute it into either equation to solve for y:

$4*\frac{1}{2}+3y=20\\ 2+3y=20\\ 3y=18\\ y=6\\ \\ 2*\frac{1}{2}+y=7\\ 1+y=7\\ y=6$

In short, x = 1/2 and y = 6.
