Use the left and right triangles. (the two smaller ones -- ACD and BCD)
By similar triangles ACD is similar to BCD
on the left AD/CD is one ratio
On the right CD/DB is the other. These two ratios are equal because they are corresponding parts.

AD / CD = CD / DB
AD = 3
DB = 12
CD = ??
Substitute.
3/CD = CD/12 Cross multiply
36 = CD^2
sqrt(36) = sqrt(CD^2)
CD = 6 <<<<==== Answer.
A <<<<====Answer.

What is the slope of the equation below?<br> 2y = 10x – 8<br> A.2<br> B.-8<br> C.10<br> D.5
blondinia [14]

Answer:

D) 5

Step-by-step explanation:

Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Divide 2 from all terms within the equation:

(2y)/2 = (10x - 8)/2

y = (10x)/2 - (8)/2

y = 5x - 4

Note the slope-intercept form:

y = mx + b

y = y

x = x

m = slope

b = y-intercept.

In this case, 5 is in place of m, or your slope.

D) 5 is your answer.
