The zero is 2, not -1
Therefore, the only correct answer is The graph of w passes through (8,-6)

What value of a will yield a solution of (2,8) for the system?
y = ax
ax + y = 16
Answers
Answer:
The value of a is 4 ⇒ D
Step-by-step explanation:
In the system of equations
∵ y = ax ⇒ (1)
∵ ax + y = 16 ⇒ (2)
∵ The solution of the system is (2, 8)
∴ x = 2 and y = 8
→ To find the value of a substitute x by 2 and y by 8 in equation (1) or (2)
∵ y = ax
∵ y = 8 and x = 2
∴ 8 = a(2)
∴ 8 = 2a
→ Divide both sides by 2
∵ [tex]\frac{8}{2}[/tex] = [tex]\frac{2a}{2}[/tex]
∴ 4 = a
∴ The value of a is 4

The Mariana Trench in the Pacific Ocean is about 36,201 feet deep. The Puerto Rico Trench in the Atlantic Ocean is about 27,493 feet deep. How many feet deeper is the Mariana Trench than the Puerto Rico Trench?
Answers
Answer:
8708 feet
Step-by-step explanation:
The Mariana Trench in the Pacific Ocean is about 36,201 feet deep. The Puerto Rico Trench in the Atlantic Ocean is about 27,493 feet deep.
We need to find how many feet deeper is the Mariana Trench than the Puerto Rico Trench.
As Mariana Trench and Puerto Rico Trench is deep.
h = -27,493-(-36,201)
h = 8708 feet
So, Mariana Trench is 8708 feet deeper than Puerto Rico Trench
