Answer:
y = 7.5
Step-by-step explanation:
given y is directly proportional to then the equation relating them is
y = k ← k is the constant of proportion
to find k use the condition y = 75 , x = 100 , then
75 = k
= 10k ( divide both sides by 10 )
7.5 = k
y = 7.5 ← equation of proportion
Answer:
0 true for all values
Step-by-step explanation:
<span>f(x<0)=-f(x>0)=-x^2+5x+12
When x>0, x^2-5x-12=12, x=8, y=12
Therefore, f(x)=12 goes through point (8,12).</span>
