we know that
A quadratic equation is a polynomial with an order of two. Its general form is
case a) 
<u>The case a) is a quadratic equation</u>
case b) 
<u>The case b) is a grade 
polynomial</u>
case c) 
<u>The case c) is a grade 
polynomial</u>
case d) 
<u>The case d) is a grade 
polynomial</u>
therefore
the answer is
The solution is x=-3, y=1, z=-1
Answer:
3(x-25)
Step-by-step explanation:
Answer:
3/4 written as a percent would be 75%
1) with the formula V=X/T, where X is distance and T is time you can verify with speed is greater
the speed of Emma is V = 3/4÷6 , V = 3/4 × 1/6 = 3/24 ⇒V = 1/8 m/h
the distance of joanie is 1 + 1/2 = 3/2 now the speed of Joanie is V= (3/2) ÷11 , V = (3/2)÷11 , V = 3/22 m/h
as 1/8 = 0.125 and 3/22 = 0.136 then the speed of joannie is greater than Emma
