Answer:
2
Step-by-step explanation:
given the difference of twice a number and one is three to find "number" let the number be x
2x - 1 =3
2x = 4
x= 2
thus the number is 2
Answer:
F(x)=-x+2
Step-by-step explanation:
equation
mx+b
m= slope
x
b = y-intercept
Answer:
D
Step-by-step explanation:
Given y varies directly as x and z then the equation relating them is
y = kxz ← k is the constant of variation
To find k use the condition y = 
when x = 1 and z = 4 , then
= k × 1 × 4 = 4k ( divide both sides by 4 )
= k
y = xz ← equation of variation
When x = 6 and z = 3 , then
y = × 6 × 3 = × 18 = 2 × 6 = 12
