Resposta: f ^ (- 1) (x) = (1/2) x-1/2
first is proportional. y is 1 and 1/4 times x
second is not proportional.
reason? divided any y value by its corresponding x value and you'll keep getting 1.25, or 1 and 1/4. and the second one is not proportional because dividing the y values by their corresponding x value will give different answers.
maybe im wrong maybe im right you choose to trust me or not.
First you’ll multiply to get 3x2x2 + 4x3. Then add them together. 12+12=24
Answer:
The answer is six
Step-by-step explanation:
12 3/5 = 63/5
2 1/10 = 21/10
63/5 divided by 21/10 is equal to 63/5 multiplied by 10/21 which is equal to 630/105 = 6 <-- answer
Answer:
13
Step-by-step explanation:
Let the number be x.
ATQ x+22=455/x. x^2+22x=455. x=-35 or 13. Since x is positive, x=13
