Compare the slopes of each line<span>. Remember, when two </span>lines are parallel<span> to each other, they will have the exact same slope. Using the equation y = mx + b where m is the slope of the </span>line<span>, you can </span>identify<span> and compare the slopes of two </span>lines<span>.</span>
Ok so first I am assuming you ment 2 sevenths so 12 divided by 2 sevenths is 42. so the father is currently 42. so when she was 10 he was 40. since 10 is 4 times 40 that is the age we need. so 42 minus 40 is 2. therefore the answer is 2.
Answer:
Given
Step-by-step explanation:
Given that: △RST ~ △VWX, TU is the altitude of △RST, and XY is the altitude of △VWX.
Comparing △RST and △VWX;
TU ~ XY (given altitudes of the triangles)
<TUS = <XYW (all right angles are congruent)
<UTS ≅ <YXW (angle property of similar triangles)
Thus;
ΔTUS ≅ ΔXYW (congruent property of similar triangles)
<UTS + <TUS + < UST = <YXW + <XTW + <XWY = 
(sum of angles in a triangle)
Therefore by Angle-Angle-Side (AAS), △RST ~ △VWX
So that:
= 
(corresponding side length proportion)
Answer:
Look below
Step-by-step explanation:
So you know a point and the slope, now you can substitute the values of the point for the equation.
It's the 2,7,3,2 one or the third one
