From the graph, we see that two similar triangles are created by using the slope of the line.
• Because the two triangles appear to have congruent angles and proportional side lengths, we can conclude with the information we have that the two triangles are indeed similar. They are the same shape but proportional with congruent angles.
• Therefore, a/b = c/d because the scale factor remains the same of both ratios.
•We can also see that in larger triangle, the slope = 3/6 and the slope of the smaller one = 2/4. 3/6 = 2/4 because 3/6 = 1/2 and 2/4 = 1/2. Therefore, the slopes are proportional and equal.
• Because the slopes are proportional and the triangles are proportional, the a/b = c/d.
Answer:
= x − 4
Step-by-step explanation:
Let's simplify step-by-step.
3x−(2x+4)
Distribute the Negative Sign:
=3x+−1(2x+4)
=3x+−1(2x)+(−1)(4)
=3x+−2x+−4
Combine Like Terms:
=3x+−2x+−4
=(3x+−2x)+(−4)
= x - 4
