Admission to the zoo costs $15 per person.
The graph y = 15x correctly represents the total cost for a group to visit the zoo.
Given;
Admission to the zoo costs per person = $15
Let:
The total number of people visiting the zoo = x
The total cost for a group to visit the zoo = y
So, y ∝ x
y = 15x
Therefore, the graph y = 15x correctly represents the total cost for a group to visit the zoo.
Answer:
To solve a system of of linear inequalities, you could do the elimination method or substitution method.
Step-by-step explanation:
- For elimination method, you can add the same value to each side of an equation. So if you have a system: x – 6 = −6 and x + y = 8, you can add x + y to the left side of the first equation and add 8 to the right side of the equation.
For substitution method, you have to:
Step 1 : First, solve one linear equation for y in terms of x.
Step 2 : Then substitute that expression for y in the other linear equation.
Step 3 : Solve this, and you have the x -coordinate of the intersection.
Step 4 : Then plug in x to either equation to find the corresponding y -coordinate.

Step-by-step explanation:
If the span is 16-ft, then the half-span is 8-ft.
Pitch = (rise) / (half-span) = 6/8 = 3/4 or 0.75 or 75% .
That's a VERY steep roof !
