Answer:
x = -4
Step-by-step explanation:
Write and solve an equation in which the slope from the definition of slope is on the left side and the given slope, 4/7, is on the right side:
7 - 5 4
m = ---------- = --------
3 - x 7
Simplifying with the aim to find the value of x:
2(7) = 4(3 - x), or 7 = 3 - x. Then x = -4.
If it uses 4 pieces of tape for a package...and each piece is 2.375 inches long, then it uses (4 * 2.375) = 9.5 inches per package.
and if u have 1900 inches of tape, 1900/9.5 = 200 packages can be sealed

Step-by-step explanation:
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
