The next number would be 160
313.75 I believe that is the correct answer or som
<h3>Answer: Choice C</h3>
======================================================
Explanation:
The x coordinate of the preimage point Q is x = 6.
The x coordinate of the image point Q' is x = 21.
The ratio of image over preimage is 21/6 = (3*7)/(3*2) = 7/2
You'll get this same value if you do the same steps with the y coordinates.
Therefore, the scale factor is 7/2 and the dilation rule is 
Note: 7/2 = 3.5
Equation 1) 4x = 3y - 2
Equation 2) 18 = 3x + y
Turn both equations into ax + by = c form.
Subtract 3y from both sides on equation 1, as well as subtracting 3x from both sides on the 2nd equation. Then, subtract 18 from both sides, and then subtract y from both sides, on the 2nd equation.
1) 4x - 3y= -2
2) -3x - y = -18
Multiply ALL of equation 2 by 3.
2) 3(-3x - y = -18)
Simplify.
2) -9x - 3y = -54
1) 4x - 3y = -2
Subtract equations from one another.
-13x = -52
Divide both sides by -13/
x = 4
Plug in 4 for x in the first equation.
4x - 3y = -2
4(4) - 3y = -2
Simplify.
16 - 3y = -2
Subtract 16 from both sides.
-3y = -18
Divide both sides by -3.
y = 6
So, x = 4, y = 6
A : (4, 6)
~Hope I helped!~
The area is 8. All you have to do is multiply 3 1/2 by 8.
Good luck!
