Answer:
Step-by-step explanation:
If a given variable varies inversely with another variable, an increase in the value of the given variable would cause a corresponding decrease in the value of the other variable. Also, a decrease in the value of the given variable would cause a corresponding increase in the value of the other variable.
If y varies inversely with x, we would introduce a cost of variation, k so that the expression becomes
y = k/x
When y = 0.25, x = 8
Substituting into the expression above, it becomes
0.25 = k/8
k = 0.25 × 8
k = 2
The inverse variation function is
y = 2/x
Answer:
n=15 j=12
Step-by-step explanation:
The scale factor is 1.5
Match up the triangles, and you can see that 12/8=1.5
10*1.5=j, or 15
18/1.5=12
$122 because if you add 55 + 67 you get 122 then you just add the dollar sign
