PLEASE HELP!!!!!!!!!!!!
Ratling [72]

Answer:

see explanation

Step-by-step explanation:

PQRS is a cyclic quadrilateral.

the opposite angles in a cyclic quadrilateral sum to 180° then

∠ Q + ∠ S = 180 ( substitute values )

3x - 8 + 3x + 8 = 180

6x = 180 ( divide both sides by 6 )

x = 30

Then

∠ Q = 3x - 8 = 3(30) - 8 = 90 - 8 = 82°

∠ S = 3x + 8 = 3(30) + 8 = 90 + 8 = 98°

∠ P = x + 15 = 30 + 15 = 45°

∠ R = 180° - ∠ P = 180° - 45° = 135°

Decide whether the relation defines a function.
diamong [38]

Answer:

A

Step-by-step explanation:

Lets first solve the relation for "y". Shown below:

3x=9-4y\\4y=-3x+9\\y=-\frac{3}{4}x+\frac{9}{4}

This is clearly an equation of a line in the form  y=mx+c

It will be a negatively sloped line, when graphed.

We can use vertical line test to determine function or relation. If a vertical line passes through only 1 point in the graph, we say that it is a function.

Think of a negatively sloped line. No matter where you draw a vertical line, it will only cut the line at 1 point.

So, this is definitely an equation of a function

Correct answer is A

In a coordinate plane what is the difference between (-3 1/2, 4) and (2 1/2)?​
Gala2k [10]

Answer:

?

Step-by-step explanation:

By difference I think you mean how far away from? I don't really know what you mean by this but I will try to help.

1/2-4=-3 1/2

2-(-3 1/2)=5 1/2

<u>-3 1/2</u>

5 1/2

Above is a fraction.

I hope that I helped. Sorry if it wasn't the answer you were looking for.

X/-2 + 6 &lt; 9 Solve for x.
satela [25.4K]
Subtract -6 on both sides
Now you have x/-2 on the left and 3 on the right
Then multiply -2 on both sides, leaving you with x on the left and -6 on the right
So x< -6
