Look at the figure below: Triangle ABC is a right triangle with angle ABC equal to 90 degrees. The length of AC is 7 units and the length of AB is 4 unit What is the length, in units, of segment CD? A. 5.50 B. 12.25 C. 8 D. 14

B. 12.25

Step-by-step explanation:

AB║CD ⇒ ∠BAC= ∠ACD ⇒ AB≅AC and AC≅CD

⇒ AB/AC= AC/CD

4/7=7/CD

CD= 7*7/4= 12.25

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
