Answer:
Step-by-step explanation:
calculate x for this equation
f(x) = -5 : -4x +2 = - 5 so : -4x =-7 x = 7/4
f(x) = 2 : -4x +2 = 2 so : -4x =0 x = 0
f(x) =6 : -4x +2 = 6 so : -4x =4 x = -1
f(x) = 18 : -4x +2 = 18 so : -4x =16 x = - 4
the domain is : D = {7/4, 0, -1, -4}
Answer:
60
Step-by-step explanation:
5 ( 9 + d )
Let d=3 and substitute it in
5(9+3)
According to PEMDAS, we do what is in the parentheses first
5(12)
Now we multiply.
60
So given the values above, if 4 pounds costs $16, this would mean that per dollar or $1 is 0.25 pounds. And the equivalent of 0.25 pounds to ounces is 4. Therefore, the given rates above are equivalent. Hope this answers your question. Have a great day!
