As the variation is direct we have:

We must find the value of k.
For this, we use the following data:
y = 200 when x = 5
Substituting values we have:

Clearing k:

Then, the function is:

We evaluate the function for x = -3
Answer:
the value of y when x = -3 is:
c.
72
equivalent ratio of 16:18 is 8:9
s1+s2>s3 where s1 and s2 are the 2 smaller sides
Choice C is the only 1 that fits
7+13 >18
C(F) is the degrees Celsius given the degrees Fahrenheit.<span />
