direct proportion y=kx , k is constant and k does not equal to 0.
17.5=k(21)
k=5/6
when x =39
y=5/6 ×39
y=32.5
X=4 because you combine 2+4 and subtract -6 then divide
24 would be the answer if its wrong i am so sorry but it has to be right
Answer:
i think its a trick question
Step-by-step explanation:
theres no way theres a righr answer the 20$ on is always ahead
F(x) = 2x - 1
subtitute x = 0 to the equation:
f(0) = 2· 0 -1 = 0 - 1 = -1
f(0) = -1
