The EASIEST way to do it, is actually start with the form a(x-b)(x-c) or intercept form since you have intercepts  

x ints at (0,0) and (4,0) so y=ax(x-4)  

sub in (2,-4) it doesn't really matter whether or not its a vertex  

-4=2a(2-4)  

a=1  

so y=x(x-4)  

expand to get y=x^2-4x which is y=ax^2+bx+c form where a=1, b=-4, c=0

A canadian goose and a Great blue heron took off in opposite directions. The goose flew at 20 mph, and the heron flew at 10 mph.
iris [78.8K]

The Canadian goose flew for 4 hours and the Great blue heron flew for 10 hours

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Let a represent the time flown by the goose and b represent the time flown by the heron. Hence:

a + b = 14    (1)

Also:

20a + 10b = 180   (2)

From equation 1 and 2:

a = 4, b = 10

The Canadian goose flew for 4 hours and the Great blue heron flew for 10 hours

Answer:

Late response, sorry. It is 750 meters.

Step-by-step explanation:

An easy method to save time is to just divide the distance by time to find what amount per second it can run. In this case, you have 120 and 4 to work with. Divide and you'll get 30 meters per second. Then, multiply 25(your seconds) by 30(the meters it runs per second) to get your answer.
