Divide everything by 4 getting:
7y=3x+21
then get all of the variables on one side by subtracting 3x:
7y-3x=21
Answer:

Step-by-step explanation:
The formula of an area of a circle:

<em>r</em> - radius
We have the endpoints of a diameter of a circle.
The formula of a distance between two points:

Substitute the coordinates of the given points A(3, 4) and B(10, 4):

Therefore we have the length of the diameter: <em>d = 7</em>
We know: <em>d = 2r.</em> Therefore

Substitute to the formula of an area:

<em>There is no such answer in the answers to choose.</em>
<em>Apparently you have some error in the coordinates of the endpoints.</em>
Answer:
XAW = 3(23) = 69 degrees.
WAY = 23 + 88 = 111 degrees.
ZAY = 8(12) - 23 = 73 degrees.
XAZ = 6(12) + 35 = 107 degrees.

Step-by-step explanation:
Hello!
You can use the Pythagorean Theorem

c is the hypotenuse which is the side across the right angle
a and b are the other sides
Put in the values you know

Square the numbers

Subtract 25 from both sides

Take the square root of both sides
a = 10.9
The answer is D) 10.9 centimeters
Hope this helps!
