A biologist took a count of the number of migrating waterfowl at a particular lake, and recounted the lake's population of water
taurus [48]

Quadratic function ( in standard form ):

y = a x² + b x + c

x = 0:

635 = 0 + 0 + c

c = 635

x = 1:

644 = a + b + 635

a + b = 9

x = 2:

719 = 4 a + 2 b + 635

4 a + 2 b = 84

and now we have a system:

a + b = 9   /  * ( - 2 )

4 a + 2 b = 84

-------------------------

- 2 a + 2 b = - 18

+

 4 a + 2 b  = 84

-------------------------

  2 a = 66

 a = 33;   b = - 24;

 Function is:

 f ( x ) = 33 x² - 24 x + 635

f ( 8 ) = 33 * 64 - 24 * 8 + 635 = 2,112 - 192 + 635 = 2,555

 Answer: The number of waterfowl on week 8 would be 2,555.

A system of equations is shown below.
prisoha [69]

Given:

The system of equations is

y=1.5x-3

y=1.5x+4

To find:

The true statement about the given system of equations.

Solution:

The slope intercept form of a line is

y=mx+b

Where, m is the slope and b is the y-intercept.

We have,

y=1.5x-3

y=1.5x+4

On comparing these two lines with slope intercept form, we get

m_1=1.5,b_1=-3

m_2=1.5,b_2=4

Since the slopes of the lines are equal but the y-intercepts are different, therefore, the two lines are parallel and the system has no solution.

Therefore, the correct option is A.

Lemur [1.5K]

Answer:

-1/2

Step-by-step explanation:

y = mx + c is the standard form of the equation where m is slope. Comparing the question to the equation we get

m = -1/2
