Answer:
339.5
Step-by-step explanation:
-67.9x+679= y
-67.9*5+679=
-339.5+679= 339.5
Answer: BD = 9 units
Step-by-step explanation:
ABQ and CDQ are congruent triangles. That means their angle measures are the same but their lengths may be proportional.
19.2 / 32 = 0.6
15 * 0.6 = 9
So the length of side BD is 9 units.
Answer:
Part 1) 
Part 2) 
Part 3) 
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form
or 
Part 1) y varies inversely with x. If y = 8 and k (the constant of variation) = 19, what is x?
we know that

substitute the given values and solve for x



Part 2) y varies inversely with x, and k (the constant of variation) = 23. What is the value of y when x = 7?
we know that

substitute the given values and solve for y



Part 3) y varies inversely with x. When y = 6.7, x = 1. What is the value of k, the constant of inverse variation?
we know that

substitute the given values and solve for k


Answer:
1/5
Step-by-step explanation:
Since it is starting with negatives, the pattern is actually increasing. They are adding 1/5 each time
