Which of the following is the value of a when the function f(x) = 3|x| is written in the standard form of an absolute value function?
-1
-3
1
3

Actually Welcome to the Concept of the Modulus functions.

Since here, the value of h and k are zero,hence

the value of the function f(x) = 3|x| is 3

====> answer is 3

b) well because you get well

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.
