Answer:

$x=\frac{27}{2}\:\text{or}\:13.5$

Step-by-step explanation:

Both triangles are shown are similar. Therefore, the ratio of their sides will be maintained. We can then set up the following proportion:

$\frac{2}{11}=\frac{3}{3+x},\\2(3+x)=33,\\(3+x)=16.5,\\x=\boxed{13.5\text{ or }\frac{27}{2}}$

Given the two points (2,4) and (-3,2), what is the slope of the line that goes through both of these points?

Andreyy89

With the formula: m=(y1-y2)/(x1-x2) you can sub in the values to get the slope (m).

m=(4-2)/(2-(-3))
= 2/5

Therefore the slope is 2/5.

slope = (y2-y1)/(x2-x1)

m =(-2-7)/(8-0)

m =(-9/8)

slope is -9/8

the y intercept is 7 (0,7)

y = mx +b

y = -9/8 x+7

Answer: y = -9/8x +7
