Correct option is C)
On putting x=2y+5 in second equation, we get
y=(4y+7)(2y+14)
⇒8y 2 +70y+98=y
⇒8y 2+69y+98=0
Discriminant D=69 2−4(8)(98)=1625>0
Hence, the equation has 2 real roots.
Therefore, there are 2 ordered pair.
Option C is correct.

Answer:
8n
Step-by-step explanation:
8n is the factor of both 8 and n. in the following question.
Factor ⇒ If a number, that use to divide another number and we get zero as a remainder, the number is called the factor of another number.
In this question, 8n is divided by both 8 and n and also we get zero as a remainder.
Therefore, 8n is the factor of both 8 and n .
Every x value should have only one value of y.
So the answer is the last choice.
Answer:
2,000 feet cubed
Step-by-step explanation:
To find volume, you use the formula Length x Width x Height. When you plug in the numbers from this equation into that formula you get 10 x 20 x 10. 10 x 20 x 10 = 2,000.
