Question 9 of 25 Does this graph show a function? Explain how you know.
O A. Yes, the graph passes the vertical line test.
B. Yes, there are no y-values that have more than one x-value.
O C. No, the graph fails the vertical line test.
D. No, there are y-values that have more than one x-value

Yes, there are no y-values that have more than one x-value.

don't know what that says sorry i can't you

step-by-step explanation:

idk what it says

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
