9 pounds
8oz x 18 = 144oz
144oz/16(oz per lb) = 9 lb
Answer:
- The function is injective but nor surjective
Step-by-step explanation:
<u>We see that:</u>
<u>For any x₁ and x₂ ∈ N, </u>
- f(x) = x₁³ = x₂³ ⇒ x₁ = x₂, both are natural numbers
It it confirmed one-to-one, hence it is injective
<u>Check the surjectivity:</u>
f(x) = y ∈ N
<u>Let y = 2, then:</u>
Since x is not natural, the function is not surjective

Answer:
Y = 50x
Step-by-step explanation:
Remember that slope intercept form is Y = mx + b indicating that m is the slope
To solve this equation use the formula
Y2 - y1 , x2 - x1:
50 - (- 50) = 100
25 - (-25) = 50
100/50 = 50/1
So the answer is y = 50x
