1 answer:
Answer:
The type of function the equation represents is "directly proportional" ⇒ B
Step-by-step explanation:
- The equation of the directly proportional is y = kx, where k is the constant of proportionality, k is a real number that could be positive or negative
- The equation of the inversely proportional is xy = k or y =
, where k is the constant of proportionality, k is a real number that could be positive or negative
Let us solve the question using the rules above
∵ The equation of the function is y = -8x
→ Compare it with the two forms above
∵ The equation is in the form of y = kx, where k = -8
∴ The equation represents directly proportional
∴ The type of function the equation represents is "directly proportional"

Answer:
(C)72.4 in
Step-by-step explanation:
Given an acute triangle in which the longest side measures 30 inches; and the other two sides are congruent.
Consider the attached diagram
AB=BC=x
However to be able to solve for x, we form a right triangle with endpoints A and C.
Since the hypotenuse is always the longest side in a right triangle
Hypotenuse, AC=30 Inches
Using Pythagoras Theorem
Therefore, the smallest possible perimeter of the triangle
Perimeter=2x+30
=2(21.21)+30
=42.42+30
=72.4 Inches (rounded to the nearest tenth)
