2x - 1 = 9 - 14x
16x - 1= 9
16x = 10
x = 10/16
x= 5/8 is the answer
Answer: ratio a:b = 3:5 p(X, 2) = p(9, 2)
<u>Step-by-step explanation:</u>
Plot points a = (12, 5) and b = (4, -3) and draw a line segment from a to b.
Notice that when y = 2, X = 9 so point p = (9, 2) <em>see graph</em>
The distance from a to p = 3√2
The distance from b to p = 5√2
So the ratio of a:b = 3√2:5√2 = 3:5 <em>when simplified</em>
<em />
<em>To find the distance, use the distance formula OR pythagorean theorem.</em>
15 x 25 = 375
15 x 50 = 750
375 + 750 = 1,125

I pretty sure you would use x over 38.00 = 20 over 100 then cross multiply them
